I am known by many names; Titch, Tiny, Pip-squeak, Shorty, Little One. At a petite 5’2″ I am not quite your average tech diver, although I am by no means alone. Diving is not the easiest sport out there, (who doesn’t enjoy rough seas, heavy gear and questionable entry points!) so here are a few tips and tricks I’ve learned along the way. 

Ask For Help

We are team divers right? Which means we always have a team to help us out. Don’t ever struggle alone, because you do not need to. Whether it’s needing help standing your twinset up, a helping hand scrambling down to the entry point, or help getting the top bolt snap of that stage up to your shoulder to clip it off on a bouncing boat, GUE divers are a helpful bunch. So if someone isn’t helping you, it might be because they haven’t realized you needed a hand – just ask!


The age old “no such word as can’t” debate. On a serious note, don’t let anyone (including your own brain) tell you that you can’t do something if that is what you want to do. If your kit is just too heavy for you, can you build up your strength with some gym sessions? If you’re struggling with your valve drills, can you spend five minutes each night working on your shoulder mobility? You just can’t understand those gas calculations, but you have access to a wealth of instructors who will run over them with you or write you a few questions to practice. Essentially, what work can you put in to get yourself closer to your goals?

Seek Advice

Two heads are better than one. I’d suggest picking someone whose opinion you value and trust. They don’t need to have the answer straight away, but maybe between you it can be worked out. You would be surprised what conundrums some of our GUE instructors will have the answer to, owing to how many divers they’ve witnessed over the years. Alternatively, find someone whom you think might have experienced the same difficulty and ask them how they approached it. Look for a solution, not excuses.

Work Smarter Not Harder

Ah my favourite phrase. You may also have heard “hit the easy button.” GUE already covers this well with the ease of things like ratio deco and universal kit configuration. First thing: this is not about being lazy and getting someone else to do the work for you; it’s a similar concept to point 2, how can you help yourself? If it’s a bit of a walk to the entry point and you’re worried about the kit being heavy, could you carry your kit there, put it down, and then go back to put your suit on and pick up all your extras? If you’re knackered when you finish the dive and aren’t sure you can carry your constructed twinset back to the car, can you take off your regs, torch canister, and your weights, and come back for just the twinset, backplate, and wing? Maybe there’s nowhere at the dive site to easily set up your kit, and there’s no way you can hold up a twinset for your buddy to heft on their back; could you buy a small collapsible bench and take that with you?

I am sure everyone has their own tips and tricks; maybe you could share yours with us.

How a Small Backplate Can Make your Diving Better

Alana Dempsey is a forensic lab tech living in Glasgow and an English interloper into GUE Scotland. I started diving in 2011 with BSAC and am a BSAC instructor. I continue to teach new divers with the Sheffield University Sub-Aqua Club and believe getting the basics right from the start is a must. Wreck diving is my passion, especially wrecks with history, (e.g. WW1 wrecks at Scapa Flow) but I can also often be found nudibranch hunting in our local dive spots at Loch Long. Tech 1 diving range is probably my favorite, but I’m starting to look for my next challenge. I’ll be a support diver on the Kalliopi project in May 2021 and look forward to developing my project skills.

The Risk and Management of Record Chasing

The pursuit of deep diving records is an unsettling but accepted facet of tech diving culture. On the one hand, we are driven as a species by our genetic predisposition to “Go Where No One Has Gone Before.” Blame it on our DRD4-7R explorer gene! On the other, many question the value and legitimacy of conducting a high risk, touch-and-go line dive for recognition and bragging rights alone. Where and how do we reconcile the two? Here diving physiologist Neal Pollock seeks to answer those questions in a compelling, principled exposition that may help you to sharpen your beliefs.

Humans have probably been chasing records as long as we have existed. Og was almost certainly proud of discovering that two stones could be rubbed together to make fire, and it likely resulted in a solid community standing for at least a while. Tempting though it may be, we cannot blame our interest in records on the advent of the Internet or social media. The Guinness Book of World Records, a small example of documenting novelty, was first published in Great Britain in 1955. The Internet and social media, however, have made the striving for and tracking of new records more intense. 

Record making is well established in diving as well as in most other communities. There are interminable lists of the first makers of equipment, the first to implement or explore, and the most extreme doers of deeds. History shows them to be pivotal, meaningful, or trivial as it unfolds. Keeping the record straight is important, but the decision as to why and whether to pursue records is worth debating. 

I am a fan of documenting meaningful events, but I have concerns over an excessive focus on arbitrary milestones. When a community puts more weight on records than actual achievements, the drive can become pointless or problematic. The pointless includes many Guinness records, such as the most number of people brushing their teeth simultaneously and the largest rubber band ball.

While some in the diving community have pursued fairly pointless but low risk records, it is the problematic ones that are a much greater concern. Underwater activities involve greater risk than many other endeavors, relying on equipment, training, technique, and practice to produce an envelope in which reasonable levels of safety can be maintained. Pursuing records is generally about pushing boundaries, and when the boundaries are set by the interaction of physics and physiology, the erosion of safety buffers can produce serious risk. The pursuit of targets can overwhelm well-founded safety concerns and common sense. 

“Record chasing can produce good outcomes, and some meaningful achievements, but when going forward is reliant on misplaced beliefs that personal motivation and superiority can overcome unforgiving limits, the outcome can be bad for both individual and community, even if considered successful.”

One of the chief challenges in diving is that the interaction of physics and physiology creates difficult-to-define limits. There are differences in tolerance between individuals and often between exposures. Different breathing gas mixtures can alter narcotic potential, respiratory gas density, decompression stress, and susceptibility to oxygen toxicity and high pressure nervous syndrome, among other concerns. Differences in workload, stress, physical fitness, and physical skill can also alter the response to other more fixed stressors. Practically, the interactions between the host of factors is complex and can make the element of chance more important than people would like to admit. A scary reality of many boundary-pushing events is the fact that getting away with something once, or even multiple times, does not necessarily make it safe, and almost certainly not safe for all.

Records achieved with a large helping of good luck still count, but they can be extremely troubling if others are encouraged to try to surpass them. Not only can tolerance and good fortune differ, the lessons learned in building to “record” performance may not be appreciated by those who follow, potentially magnifying the risks. 

Care is warranted to decide on what “records” are truly worth pursuing and what should be left alone. A simple practical test is whether an activity serves any purpose beyond the record attempt. If there is no other benefit or purpose, the value in it may not be sufficient to continue, especially when the associated risks may be high.

Record attempts are sometimes pursued by relative newcomers to a field. It is unclear how much of this is due to simple enthusiasm or a desire to stand out, but all such efforts are best met with counsel before encouragement. The field needs leaders, and the next generation of leaders, but this requires keeping those with potential both healthy and engaged. This may come down to mindset—finding what is most important and appropriate to pursue as part of personal growth. 

Leaders who want to establish themselves are best served by ensuring that they have the best understanding, skill, and experience within the realm of what they will need to do rather than pushing the envelope for increased fame. Chasing records by sacrificing safety margins and/or ignoring compromised states of affairs is not compatible with accepted best practice. Those looking up to leaders for inspiration may not fully appreciate the issues and concerns, but the best leaders will be conscious of the total impact their efforts can have on others.

Bragging about exceptional or record exploits is problematic in that it can encourage others who may be inadequately prepared to follow suit. It may be a hard reality for the keen, hungry, and superbly confident instructor to accept, but they can provide a much better service to their students by encouraging them to stay within the accepted realm of operational safety. This is often most effectively demonstrated through example. The goal should be to promote a long and healthy diving life, effectively achieved by solid training and an instilled appreciation for the value of robust safety buffers and a constant revisiting of “what if” preparation. 

We should recognize the meaningful efforts in the community, but without losing sight of the implications of such endeavors. Promotion of a positive safety culture requires questioning whether things should be done, and how things that should be done can be done with appropriate safety margins. If meaningful efforts result in record achievements they should be applauded, but always with an appropriate framing of any associated value, limitations, hazards, and implications.

Reporting the exceptional is important, but a high priority should also be put on recognizing activities and efforts that are unexceptional in outcome due to appropriate preparation and execution within safe boundaries. Efforts to improve training, awareness, and operational safety must always be promoted. Safety programming is challenging since, when it is effective…, nothing happens. Ongoing commitment is required to ensure that it continues to be effective.

I would posit that the best record attempts are those pursued without fanfare, moving quietly from concept through to safe workup stages and then safe completion. The reporting of record efforts should always consider the value and relevance of the activity. Achievements that violate the criteria for safe performance should be neither encouraged nor glorified. 

We live in a time when the pursuit and promotion of records can be expected to continue, but appropriate framing can help to ensure that the community benefits from a sustained focus on safety and thoughtfulness.
