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.

Greetings Tekkies,

This December marks the second full year of publishing InDepth, and what a crazy year it’s been. With the pandemic still raging throughout most of the world, it has been a most challenging year for the diving industry, as I’m sure you’re aware. I would like to take this opportunity to thank you, our readers for your continuing interest and support, and also thank our thoughtful contributors who make the blog possible.

Over the last year, we published nearly 100 InDepth stories covering the latest developments in exploration, technology, training, conservation, diving science & medicine, image making and technical diving culture. We also added select translations into Chinese, Italian, and Spanish . In doing so, I believe that we have grown our coverage in terms of breadth, depth and sophistication. Call it, a geeky labor of love!

In addition, we’ve added some depth-full sponsors to the mix, that have made it possible to grow and sustain InDepth. Our special thanks to DAN Europe, Dive Rite, Divesoft, Fourth Element, Halcyon, The Human Diver, and Shearwater Research. May your brands continue to flourish! 

Similar to 2019, we celebrate the coming new year with our Most Read Stories from 2020/2019. If you like what you read, please SUBSCRIBE, it’s free! That will ensure you’ll get our latest stories and content delivered to your inbox. Here’s to a hopefully wet and most excellent 2021!

9. Situational Awareness and Decision Making In Diving

Situational awareness is critical to diving safety, right? But how much of your mental capacity should be devoted to situational monitoring, e.g., How deep am I? How much gas do I have? Where is my buddy? Where is my boat? More importantly, how does one develop that capacity? Here GUE Instructor Trainer Guy Shockey, who is also a human factors or non-technical skills instructor, explores the nature and importance of situational awareness, and what you can do to up your game.

10. Examining Early Technical Diving Deaths

The early days of technical diving were marred by an alarming number of fatalities that threatened the viability of this emerging form of diving. Here InDepth editor-in-chief Michael Menduno presents the original accident analyses of 44 incidents that resulted in 39 fatalities and 12 injuries, as reported in aquaCORPS Journal and technicalDIVER in the early to mid 1990s.

11. A Voice In The Wilderness

Just when you thought you’ve seen it all, along comes underground picture-maker SJ Alice Bennett, who is shedding new light on the dark, moody, twisting karst passageways that form what explorer Jill Heinerth calls “the veins of Mother Earth.” If you’re ready for a new perspective on the ‘doing of cave diving,’ switch on your primary and dive right in.
