Frequently Asked Questions

Orders (11)
We accept most major credit cards (Visa, American Express, Discover, MasterCard) as well as PayPal. We use an external payment processing service and we do not save any credit card numbers in any way.
Our standard shipping method is USPS, and depending on the weight of your order, you will probably be able to choose from First-Class (less expensive, but takes longer) or Priority (costs more, but arrives sooner). We also offer UPS, which includes a tracking number, but this generally costs quite a bit more for international orders.


If you are looking for less expensive shipping options, there are a few that we suggest:

  • You can consider choosing USPS First Class Mail, which takes a bit longer but can cost significantly less for international orders.
  • You can get together with other GUE divers in your area and place an order together, then split the shipping when you work out the individual costs among yourselves. This can be a very cost-effective way to get merchandise if you want a number of items and/or you know multiple other people who also wish to order merchandise from GUE HQ.
  • You can time your order with a dive trip you or a friend plan to take to the U.S., then have your items shipped to your temporary address or, if you are visiting High Springs, pick them up from GUE HQ. In order to make sure your items are in stock and can be shipped at the appropriate time to arrive during your travel window, we recommend placing orders no later than one month before your/your friend's arrival in the U.S. This gives us time to order and receive any out-of-stock items, and to time the shipment of your order accurately so that it arrives during your specified window. If you plan to use this method, as always, we suggest contacting GUE HQ's shipping representative at orders@gue.com as soon as possible to get the best possible results.
  • A final option is to see if there is a GUE Affiliate in your country or in a country closer to yours than the United States who sells the item you want to purchase. You can get contact information for these centers by clicking on their logos on the GUE Affiliates page, and then call or send an email asking if they have your desired item in stock. Please note that stock at GUE Affiliate dive centers and IDCs can be VERY limited and is chosen entirely at the discretion of the Affiliate itself. They are under no obligation to fill orders they are not prepared for, and this is listed only as a resource for the convenience of our customers and the promotion of our Affiliates.


If you have any further shipping or merchandise questions, please email orders@gue.com.

Please contact orders@gue.com if you would like to have you order shipped with any method not available on our site automatically, such as UPS with Saturday Delivery, USPS Express Mail (domestic or international), etc. You will be provided with an estimate of the cost of your preferred method as soon as possible, and GUE HQ will help you complete your order as soon as payment information is provided.
Any merchandise ordered online is shipped from our HQ in High Springs, Florida, USA. If you live outside of the United States we have to use international shipping, and aside from the $2.00 handling fee added to each merchandise order, there is absolutely no "padding" in the shipping fee you are charged.


The web site estimates all shipping costs based on up-to-date prices and the combined weight of your merchandise. If the web site overestimates your shipping costs, you will be refunded the difference in cost to the payment method used on your order, and you will receive an email explaining the refund. GUE HQ never seeks to profit in any way from shipping charges.


If you are looking for less expensive shipping options, there are a few that we suggest:

  • You can consider choosing USPS First Class Mail, which takes a bit longer but can cost significantly less (often $20-$30 less) for international orders. USPS First Class International shipping is now available as a selection in checkout if it qualifies, meaning your order weighs 4 pounds or less.
  • You can get together with other GUE divers in your area and place an order together, then split the shipping when you work out the individual costs among yourselves. This can be a very cost-effective way to get merchandise if you want a number of items and/or you know multiple other people who also wish to order merchandise from GUE HQ.
  • You can time your order with a dive trip you or a friend plan to take to the U.S., then have your items shipped to your temporary address or, if you are visiting High Springs, pick them up from GUE HQ. In order to make sure your items are in stock and can be shipped at the appropriate time to arrive during your travel window, we recommend placing orders no later than one month before your/your friend's arrival in the U.S. This gives us time to order and receive any out-of-stock items, and to time the shipment of your order accurately so that it arrives during your specified window. If you plan to use this method, as always, we suggest contacting GUE HQ's shipping representative at orders@gue.com as soon as possible to get the best possible results.
  • A final option is to see if there is a GUE Partner Facility in your country or in a country closer to yours than the United States who sells the item you want to purchase. You can see the GUE Partner Facilities in the banner at the bottom of the page. You can get contact information for these centers by clicking on their logos, and then call or send an email asking if they have your desired item in stock. Please note that stock at GUE Partner Facility dive centers and IDCs can be VERY limited and is chosen entirely at the discretion of the Partner Facility itself. They are under no obligation to fill orders they are not prepared for, and this is listed only as a resource for the convenience of our customers and the promotion of our Partner Facilities. Partner Facilities may choose to honor GUE Membership discounts, but are not obligated to do so.


If you have any further shipping or merchandise questions, please email orders@gue.com.

If your merchandise order includes a tracking number, you will receive an email with that information when your package is shipped. It can take 24-48 hours for the tracking information to begin to be updated.


For international shipments via USPS Priority or USPS First Class, the USPS cannot update your tracking information after the package is transferred to your home country's postal service. Whether your tracking information will continue to be updated at all is entirely at the discretion of the postal service of your country. If you do not receive your package within 4 weeks of it leaving the U.S., please contact orders@gue.com.


These gear stickers are made by a 3rd party vendor local to GUE HQ, and thus take time to order, receive, and ship. Stickers are ordered on or around the 1st and 15th of each month, depending on business hours, and should be ready to ship within two weeks. Unless otherwise noted in your order comments, your billing address will be used for shipment.


For orders containing gear stickers, no shipping costs will be estimated automatically. You will be asked to choose between domestic and international shipping only, or to say that you are purchasing other merchandise with which your stickers can be shipped. "Other merchandise" does not include course registrations, electronic materials, software, or certification cards of any kind, since these are not merchandise and are not processed or shipped in the same way. If you choose "I'm ordering other GUE merchandise" when you did not actually purchase any eligible merchandise, your gear stickers will not be shipped until appropriate shipping costs are covered. You will receive an email from someone at GUE HQ explaining the situation and requesting either the $3 domestic or $5 international shipping charge.


GUE and its partner vendor will do the best we can with any special non-English characters. We are generally able to accommodate any requested characters, but if you are worried about the spelling of non-English-alphabet names or words, please leave an order comment and we will be sure to ask our vendor to lend some extra attention to the accuracy of your stickers.

Please contact info@gue.com with a full description of the sizes you might need and the specific items you are interested in ordering.
If you placed an order for an item that you no longer want or wish to change (such as a size L to a size M), the first step is to contact HQ immediately at orders@gue.com to let us know your situation. If the incorrect item that you ordered has already arrived, then you will need to ship it back to GUE. As soon as we receive the item you wish to exchange, we will ship (at your expense) the replacement item. If the order has been shipped, but hasn’t yet arrived, you will need to wait until it does, and then follow the above step.


If you have placed your order within the last 48 hours, there is a chance it has not yet been shipped. In this case we can easily adjust the order to reflect your request. If you are unsure of the status of your order, please email orders@gue.com or call 1-800-762-DIVE (3483).

If, when you received your order, there were incorrect items included (example: you ordered a large t-shirt but received a medium), we will cover the shipping cost back to us, and the cost to send the correct item to you. If you find yourself in this situation, please email orders@gue.com.
Please contact info@gue.com with as many details as possible about what you are looking for.


If you don't know, we probably don't know either.


If your package was shipped via USPS, you should have received an email with the subject "GUE has sent you a package!" that contains a tracking number. US customers should see their tracking updated through delivery. International customers will see that their tracking information is updated until your package leaves the United States, at which time, it is up to the discretion of your national postal service whether to update it further. GUE does not have any more information than you do, and recommends calling your local post office if it has been more than 4 weeks since your order was shipped.


UPS provides updated tracking through delivery for US and International shipments.


Some postal services take longer than others to process items through customs. If there is anything we can do to make this process go more smoothly, please leave an order comment and we will be happy to oblige as best we can.


GUE has no control over what happens to an order once it leaves our office, and cannot take responsibility for lost merchandise orders that are the result of incorrect or incomplete addresses, mistranslation, inability to deliver, change of address, or postal service mishandling or loss. GUE is happy to provide any information about your package should you need to submit a claim to USPS, but we cannot undertake this process for you and cannot be responsible for following up on any claims made with USPS.


If you still have a question about your package, please email orders@gue.com.

Classes (7)

GUE offers a wide variety of high-quality, comprehensive SCUBA classes ranging from recreational open-water training to advanced technical and cave diving. GUE courses include:

  • GUE Fundamentals, our most popular course
  • Recreational open-water courses, divided into Recreational Diver 1, 2, and 3
  • Cave diving courses, divided into Cave Diver 1, 2, and 3, plus Underwater Cave Survey
  • Technical diving courses, divided into Technical Diver 1, 2, and 3

The structure of GUE training can be found on the Explore GUE Courses page, which includes links to more extensive course descriptions.


For the most up-to-date and complete descriptions including prerequisites, topics, required skills, and equipment, you should always check the GUE Standards.

Because of GUE’s continuous growth, our Instructors can be found all over the world. To find an Instructor in your area, visit our Instructor page. Can’t find one close to you? Don’t worry! Many of our instructors are flexible and willing to travel. For more details, visit the instructor’s resume page by clicking on their name.
The cost of a GUE class can vary, as GUE HQ does not set guidelines as to what instructors are required to charge. The only fee that we require to be paid directly to HQ is the registration fee, which gives you access to your class materials and allows you to apply for a class. This fee covers the cost of those materials, processing, and certification. This fee varies from $45 for non-certification classes (GUE Primer, Doubles, or Drysuit Diver) to $95 for foundational training (including GUE Fundamentals and the Recreational Diver track) to $125 for advanced training (including the Cave Diver and Technical Diver tracks).
The registration fee charged by GUE HQ is separate from any course fees charged by your instructor and covers the cost of those materials, processing, and certification. This fee varies based on the class you are taking:
  • $45 for Doubles or Drysuit Primer (no certifications) and Gas Blender.
  • $40 for GUE Fundamentals Part 1.
  • $55 for GUE Fundamentals Part 2.
  • $95 for GUE Fundamentals, Recreational Diver 1, 2, and 3, Documentation Diver, DPV 1 and DPV Cave.
  • $125 for Underwater Cave Survey, CCR, and Rebreather Diver.
  • $150 for Cave 1 and 2, Tech 1, 60, and 2.
The first step towards registering for a GUE class is to verify with your instructor that there is a spot reserved for you. GUE HQ (and thus our web site) does not substitute for direct communication with the instructor concerning class availability.


The next step is to create a free account on the GUE website and complete your Student Profile, located on the right-side user menu. Once you have done this, you can find the class you want to take by clicking on "Diver Training" in the top menu, then on "View Course Schedule." Once you find the class you wish to sign up for, you will be prompted to pay the registration fee. Paying the registration fee means that you apply for the class directly, and your instructor will be notified.

GUE Fundamentals training is an immensely popular course, affecting the way many individuals think about Scuba diving. Initially GUE Fundamentals was structured to prepare divers for the rigors of technical diving and was established as a pre-requisite for this training. However, most difficulty in diving relates to poorly developed fundamental skills; therefore, GUE began to promote this course to a broader community. Divers around the world have embraced this training as a way to greatly improve the safety and fun within their diving.


GUE Fundamentals may be conducted in single tanks for recreational divers; technical divers interested in advanced GUE training will use twin tanks. To enter GUE Fundamentals individuals must hold an Open Water rating from a recognized agency (most major agencies are acceptable). GUE training focuses upon the fundamental skills including theory and practical application of buoyancy, trim, teamwork, rescue skills, Nitrox, breathing gases, gas consumption, dive planning, equipment configuration, decompression theory and more. GUE Fundamental dives are video-recorded and used as a teaching tool to help improve diving skills.


You can learn more about GUE Fundamentals on its course page or in the GUE Standards.

Check to make sure that you have entered something in every field. If you have left anything blank, your form will not be processed. Once you have made sure that there are no blank fields and it still shows as incomplete, please contact info@gue.com.
If you have filled out your QC form via your “My Courses” page, and verified that your contact information on your GUE student profile is current (My Student Profile --> Student Information), then your certification will usually be processed and mailed within 1-2 weeks. However, this is dependent on your instructor having completed your evaluation. If you haven’t received your card 4-6 weeks after your class is over (international mail can take 2-4 weeks for delivery) and have filled out your QC form and updated your contact information, then please contact certifications@gue.com.
Please email HQ at certifications@gue.com or call 1-800-762-DIVE (3483) with any questions or concerns about your certification.
GUE divers are required to perform twenty-five dives at their highest level of certification over the three-year period to re-qualify for an additional three-year period. To renew, simply visit your “My Courses” page where you will find a link to access the renewal form. Once the renewal form is complete, you will be prompted to pay the $30.00 renewal fee. Once submitted, HQ will receive notification of the renewal, and upon review will process it accordingly.


If you choose to pay to renew your certification at the same time as placing a merchandise order, please note that for quality assurance purposes, these orders are handled separately, and your certification card will not be included in the same package as your merchandise order, unless you leave an order comment specifically requesting that one be held until the other is ready to ship.

To request a replacement card, please go to your “My Courses” page and there you will find a Certification Card Replacement link. Once you complete the form and submit the $30.00 replacement fee, we will receive your request and process it as quickly as possible.
Students wishing to upgrade from a Recreational Fundamentals pass to a Technical pass are not required to pay the registration fee again. If your original fee has expired, simply contact HQ (info@gue.com) with your name and the date of the class you are trying to register for. Once we confirm with the instructor that you are approved for this class, we will register you.


There is a $30.00 fee to receive your updated Fundamentals Tech Pass card.

A provisional rating means that you didn’t fail a course, but you still have skills to work on before you are evaluated as “Pass,” and are eligible for official GUE certification. Divers should be aware that the original instructor is solely responsible for updating this rating. An instructor may make specific arrangements with another GUE instructor but the original instructor is ultimately responsible for upgrading their student’s provisional rating through the GUE website. The time and fees associated with provisional upgrades are entirely at the discretion of the instructor, however HQ requires you to pay for course registration again if the time since the original course has exceeded 6 months.
If you do not have your certification card, either because you haven’t received it, have lost it, realized it needs to be renewed, or forgot it when traveling, please contact info@gue.com or 1-800-762-DIVE (3483) and provide all of your pertinent information. We will do everything we can to help resolve your issue based on the circumstances surrounding your request.


If you haven’t received your card yet, please be sure you have filled out your QC form. Please note that if a card is requested to be sent any other method than USPS First Class, you will be required to cover the shipping cost.

Becoming a GUE Member is quick and easy, and can be done entirely online.


GUE offers a range of membership levels to suit any budget. To view the various levels and their benefits, please visit our membership page here.

Users with an active membership have the option to move to a higher level membership for a special upgrade price. Upgrading works just like purchasing a new membership—it is active for one year from the purchase date and includes all listed benefits during that time.
The first step to upgrading your membership is to first verify that you currently have an active membership. If your membership has already expired, you are no longer eligible for an upgrade and will need to purchase a new one. If you do have an active membership, you can click here to view your available options.
No, GUE certification and membership are entirely separate designations. GUE is a 501(c)(3) educational not-for-profit organization that is entirely supported by memberships, sales, and donations. GUE is also a vibrant international community, and we highly encourage all of our divers to explore our membership options and choose the level that best suits them.


GUE Membership offers a number of benefits, depending on the level, all of which are listed and up-to-date on our membership page.

No, GUE certification and membership are entirely separate designations. Anyone who fulfills the course prerequisites is eligible to take a GUE class.
If you are attempting to redeem your free course registration fee that is part of a Gold level or higher membership, please contact HQ at info@gue.com or 1-800-762-DIVE (3483) and we will activate that for you.


This membership benefit MUST be used during the one-year period of the membership with which it is associated. No membership benefits may be rolled over, banked, or in any way valid more than one year after purchase of a membership, even if it is renewed without interruption. For example, you cannot redeem two free course registrations after renewing the Gold membership you have had for one year already. Additionally, free course registration benefits cannot be applied to registrations purchased before the period of membership. These rules apply to all levels of membership that grant free registrations (Gold, Scholar, and Platinum). If this conflicts with your diver training plans, remember that course registrations are valid for nine months from the date of purchase. If you have any questions about this policy, please contact GUE HQ as soon as possible.

There are many possible reasons why you are not receiving Quest list emails. First, is your membership still active? If not, then you can renew here. If your membership is active, is your email’s spam filter blocking the incoming messages? If it is, check your filter’s settings. If neither of these are the problem, please contact info@gue.com, and we will verify your subscription.
Annual auto-renewal is an optional selection you can make at the time you purchase a GUE Membership. If you select annual auto-renewal, your GUE Membership charges and benefits will recur each year on the same date as your original order. Additionally, you can receive a 10% discount on your first year if you sign up for annual auto-renewal.
PDF books are downloadable files, accessible from your 'My account' section when logged into the website (the menu on the right-hand side of the page). On your account page, navigate to the 'Files' tab.
Most of the books can be opened using Mac Preview, but all can be opened using Adobe Reader, a free download available here: Get Adobe Reader Software files are also available in here.
If you purchased the electronic file by itself, the link should be active within one hour from purchase, once the system auto completes your order. If the electronic item was purchased in the same transaction as tangible objects that require shipping, the link will be active as soon as those items are shipped. If for some reason you need the file right away, please contact info@gue.com or 1-800-762-DIVE (3483).
Yes. Once you have installed the DecoPlanner, please see the Help menu in the program. The Help section explains how to use the program.
Contact HQ with your HotSync ID and we’ll be able to resend you the registration key. Don’t know your HotSync ID? On your device, go to the DPlan tab at the top of the screen, then select options and then select register. Your HotSync ID will be listed on the screen.
The link to download purchased software remains active for 90 days. If something happens to your computer during this time period, simply access your “My account” page and re-download the program from the 'Files' tab. If you need replacement software more than 90 days after purchase, you are entitled to obtain a 50% discount from the current purchase price of the product in question; please contact info@gue.com with proof of purchase to obtain your discount. This replacement offer is not valid when a new version of software has replaced the software in question. In this case, the customer is able to purchase the new product at the discounted upgrade price.

Please note: When you buy a software program from GUE you will download it as a ZIP archive. This ZIP archive contains the program installer, and it is very important that you keep this file in a safe place. We highly recommend that you save the file to an external memory device such as a USB drive, CD/DVD, or external hard drive, so that in the event of a computer crash or theft, you will not need to re-purchase your software.

To run DPlan on anything but Palm OS you need a third-party environment that enables this. Although GUE HQ does not have any experience with it, we have had reports about StyleTap being a functional option to run DPlan on other devices. You can download/purchase StyleTap here: www.styletap.com
While we recognize that there is a growing demand for iPhone, Android, Blackberry, and other Smartphone versions of DPlan, and a Mac version of DecoPlanner, we do not currently posses the resources to devote to such a project. It is, however, something we would like to pursue in the future.
Please read these instructions on how to run DecoPlanner on Mac!
About GUE (2)
Global Underwater Explorers (GUE) www.globalunderwaterexplorers.org is a non-profit organization formed by leading explorers, researchers, and educators; these individuals are dedicated to the training of divers as well as the study and protection of the aquatic realm. GUE and its associated projects are responsible for conducting some of the world’s most remarkable dives, setting numerous world records in the process. The success of this group encouraged great interest in their diving and procedures. Of particular interest is the promotion of solid fundamental skills for all divers (recreational and technical) as well as their adherence to a common diving standard. This general standard requires the following:
  • Divers use the same equipment configuration; this enhances safety and efficiency.
  • Divers use the same well-defined set of breathing gases, including Nitrox, Helium and Oxygen; standard mixes eliminate complexity and greatly enhance safety.
  • Divers use a team approach during all dives, facilitating fun and safety.
  • Divers must have a solid grasp of fundamental diving skills, including refined buoyancy, trim and teamwork; these skills must be developed in concert with the type of dive pursued. Difficult dives require very high levels of skill development.

Over time it became obvious that divers experiencing difficulty in advanced dives and during technical training were suffering from poorly developed fundamental skills. Among other deficiencies basic skills were lacking, including good buoyancy control, efficient propulsion techniques and effective air sharing techniques; this was true despite the fact that applicants were often experienced divers. Consequently, the founders of GUE attempted to shift the industry away from quantity and toward a focus that insisted upon greater capacity from motivated individuals. Over time it became apparent that too many factors were discouraging migration to longer more demanding instruction. Profit driven forces coupled with general inertia encouraged the persistent reduction of diver training requirements. As a non-profit education, research, conservation and exploration agency Global Underwater Explorers appeared better situated to encourage robust training; ultimately this emphasis led to the expansion of GUE’s diver training division.
We are thrilled you're interested in supporting GUE. This support can take many forms, including membership, direct donations, or support of one of GUE's many projects and conservation initiatives. You can learn more by visiting our page on supporting GUE!
The full outline of GUE instructor development can be found in section 3.5 of the GUE Standards. A more detailed explanation can be found in Quest 16.2, in Dr. Panos Alexakos's article Becoming an Entry Level GUE Instructor: the Two Signature Process. Of course, if you have any questions don't hesitate to contact info@gue.com or a GUE Instructor Trainer or Evaluator.
GUE does not do any crossover instructor training. All GUE instructors must follow the GUE certification and instructor training process. GUE's curriculum can differ significantly from that used by other agencies and thus does not allow for effective "crossover" instruction. This policy does not differ based on the type or level of instructor you are or wish to become.
