A Beginners Guide to Tech Diver Jargon

Tech Diver

Tech DiverSo, you have decided to be a tech diver. You have picked your instructor with great care and you feel confident about your future.  Now all you’ve got to do is pop down your local dive centre and get yourself some shiny new kit. How hard can that be?

Well you are faced with a few problems. If you are heading down the rebreather path, 90% of dive retail staff will spend an hour telling you what an idiot you are, can they have an invite to your funeral, “my Grandad wore a rebreather in the war putting bombs on Jerry boats”, etc, etc, blah, blah.

If you are going down the open circuit route those same staff will tell you what a pile of bollocks tech is quoting such memorable lines as “I went to 60 metres on a single ten in Sharm last year,” “All that planning and f**king about for a 60 minute dive, I went to Wraysbury last week and did 62 minutes on a single ten!”

And a lot of the time whether you are CCR or OC the shop geezer has no idea what the fook you are on about when you ask for specialised equipment anyway.

OK, so I’m exaggerating just a little bit. Or am I?

Tech DiverSeriously though, more and more dive shops are embracing tech and will have more than a basic knowledge of as technical divers requirements. They will also look after you and give you the guarantee that if the kit is not up to the job they will replace or fix it. A lot of stores will actually help you build your kit, and these are the primary reasons I buy most of my kit in stores rather than the Internet. I’m sure you’ll all agree that buying recreational gear is hard enough without some serious advice and help from the shop dude……so just imagine tech!

In this article, let’s have a serious laugh at all the technical equipment names and what they actually refer to so we can impress the person behind the counter (or know when he or she is pulling a fast one).

  • Twinset with manifold with wide bands – two tanks stuck together with really fat (and I mean ‘PH’ PHAT stainless steel bands) with a knob in the middle to turn one side off (kind of).
  • Back Gas – Normally this refers to the twinset or actually the gas carried in it.
  • Environmentally sealed, balanced adjustable regulators for back gas – high quality regulators for the twinset. Shiny new regs compliment the wing. Very techy! You will need two sets, one primary and one backup. It’s all about redundancy. You don’t need an octopus on each set though! And you only need one gauge.
  • Long hose – this is a 2 metre hose for the primary regulator. You’ll need a P-Clip attached to this hose so refer to P-Clips further down.
  • Short Hose – this is the backup regulator that is worn around the neck by means of a bungee tied around the mouthpiece.
  • O2 Regs – regulators that are Oxygen clean so they don’t blow the back of the boat off when you turn them on (Running O2 through a dirty regulator can have catastrophic results). Unfortunately, in Europe they will probably come with a nice new M26 thread instead of standard DIN attachment. This thread is F’ing useless as it presumes that all divers are idiots and can’t manage to put the O2 regulator on the O2 tank. Typical Brussels and all it’s bollocks. Get a standard DIN if you can and f**k Europe and its directives!!
  • Wing – a flying SMB? No, it’s a BCD that only inflates behind the diver, like a wing. Wild, eh? Wings have better buoyancy control, nice and flat and clean, less drag, and Jedi looks. BCD’s are soo betamax! They come in single or double bladder. This means that you have a primary inflator on a single and a primary and backup inflator on a double. Again it’s all about redundancy. The regulators on the twinset feed both inflators. You do not need a double bladder wing if you dive drysuit, as the drysuit is your buoyancy backup in the event of a wing failure.
  • Plate – A Stainless Steel, Aluminium, Polycarbonate or even Titanium plate to which the twinset is attached. The reason we use a plate is to provide rigidity for the diver.
  • Harness – This is webbing and D Rings attached to the plate. There are many different styles of harness available but they all do the same job, they just have different features. The beauty of having a wing, plate and harness is that there is no clutter around the diver making him or her very streamlined.
  • Umbilical lights – This is a canister light with an umbilical wire that leads to the light head. If you are serious about diving, this is the style of light for you. Available in HID or LED. LED is now the standard as the bulb has an incredibly long lifespan and is highly shock resistant unlike the HID light, which is quite fragile and immensely expensive to replace. The design allows a small light head to be worn on the hand and still allow the hand to be free to work (unlike a standard hand held torch). These are good for tech, good for rec.
  • Red Bag – Red SMB (Surface Marker Buoy). Using one of these properly will make you a better recreational diver as well.
  • Yellow Bag – You guessed it but this time it’s yellow.
  • Dry Bag – This is not a dry SMB, but a drysuit. Must be black otherwise you’re not going to be recognised as being serious. Will keep you warm, so you can dive year round, and you will be amazed at the buoyancy and trim you will achieve in a drysuit.
  • Gators – Nothing to do with big crocodile type animals found in the Everglades. Gators are much like climbing gators; they stop the material on the calves flapping about. For a diver, this means we are streamlined and also, you don’t have to wear ankle weights, as the air simply CAN’T get to your feet. I reckon that 90% of divers using ankle weights in drysuits can benefit using gators and heavier fins.
  • Jets – Lovely small bladed rubber fins that will allow you to frog kick, helicopter turn and reverse fin with ease. Perfect for tight overhead environments. I wear them, but I can do all of these fin kicks in Mares Quattros so don’t get too carried away. Split fins will NOT cut it I’m afraid. Get some duck tape out and put them back together how they were meant to be, instead of that manufacturing defect that they have convinced us is an enhancement.
  • Reel – A pile of string on a spool with a handle. Some are awesome; most are suicidal in the wrong hands.
  • Spool – A pile of string on a spool with NO handle.
  • Z-knife – This is a plastic frame that holds a razor blade in a preformed C- section. Z knives are used for cutting while pulling.
  • Depth Timer – A digital depth and dive timer.
  • Multi Gas Switchable Dive Computer – This is a computer that can handle the rigours of mixed gas diving. Suunto, Scubapro, Hollis etc all make multi gas computers. Most modern dive computers will allow you to select and switch two different gases while underwater; perhaps you are already wearing one? However, there are many machines available now that are able to store and switch many different gases. These computers can handle Air, Nitrox and Trimix and can even bounce between Open and Closed Circuit. A Multi gas computer is fast becoming standard equipment for tech divers.
  • P Clip – get that shit clipped away…. When the shit hits the fan, you know where it is. A P-clip is like the clip you would use to clip (a gated clip with a swivel) a leash to a dog collar but bigger and of higher quality. They come in many different styles and we use them primarily to secure the primary regulator when not in use and also the SPG. Stainless Steel is the choice for most tech divers as brass clips ‘gum up’ quite quickly. Plus – Brass rhymes with arse.
  • Double ended P Clip – Same as above but two gates and no swivels. Used on stage bottles, reels, spools and we generally have one attached to our kit for emergency use if another clip were to break.
  • Snorkel – I am still trying to work out how to breathe through this appendage underwater. If anyone has any clues, I am willing to try, but in my experience the only thing it’s good for is getting alcohol into your mouth really quickly, whilst being laughed at by all your friends. If you want to have a laugh, take one of these in a cave programme.

Tech DiverTech DiverNow you have a basic idea of some technical jargon. Hopefully you have got the idea that tech is really not that complicated. I believe that most divers are put off doing tech training as we make it out to be so complicated and dangerous. It isn’t! Maybe it was once but now things have moved on and most people can actually participate.

For those techies reading this, I have written it with a recreational diver in mind. I want divers to come over to the dark side and have a go. We all know that once you get to the dark side, we normally find it’s really sunny.

Veterans take part in Hadrian’s Wall trek to raise funds for their ‘Red Sea family’

Published

on

A group of veterans from Scuba Diving rehabilitation charity Deptherapy have pledged to take part in a 40 mile expedition-style trek along historic Hadrian’s Wall this July to raise funds for the staff at Egyptian dive centre and resort Roots Red Sea.

The dive centre in El Quseir has been closed since the start of the Covid-19 Pandemic last Spring and with Egypt now on the red list for UK travellers it is unlikely to be able to re-open in the near future. UK couple Steve and Clare Rattle, who own Roots Red Sea, have been supporting the 16 staff of the dive centre and their families but faced with an ever increasingly uncertain future, the Deptherapy beneficiaries wanted to add their support too.

Roots Red Sea is Deptherapy’s home from home in Egypt and the location where the charity’s majority of overseas training courses and expeditions are held. The facilities at the Egyptian dive centre and resort are a perfect fit for the charity offering an ideal combination of self-contained and fully adapted accommodation, as well as a team of highly trained staff.

Deptherapy normally runs 2-3 trips to Roots Red Sea each year but recent and planned trips continue to be a casualty of Covid. For the time being, training has shifted to UK waters, but their Egyptian family is never far from the minds of the Deptherapy Team.

“We’re hoping to raise £3,000 for the staff at Roots to support their families due to hardship caused by the pandemic,” explains Tom Oates, Deptherapy Divemaster, Ambassador and former Scots Guard.

“Deptherapy has been a lifeline for so many of us beneficiaries and an essential part of that journey has been our scuba diving adventures at Roots Red Sea. We view the staff at Roots as part of our extended families. They have become close friends. The welcome, service and care we are shown is unbelievable but now it is our turn to give something back. The staff at Roots have given us everything and have helped to save and change our lives. Now, they need our support.”

“This is an amazing endeavour from the guys at Deptherapy,” says Steve Rattle, who is organising the logistics of the trek which is planned to stretch over several days. “We have supported the charity for many years; it’s always been a delight to have them come to Roots and to see them really benefit from the experience. Now the tables are turned, and it is the families of Roots that are in need of help. It is really humbling to have Team Deptherapy now raising money for them. Awesome effort!”

The fundraiser is scheduled to take place from 12th -16th July 2021 starting from Heddon on the Wall in the east to Lenercost in the west. The route has been designed to take in a variety of features including many historical sites such as the Roman Army Museum at Greenhead.

Please give generously to sponsor Team Deptherapy in their quest to raise £3000 for the families of Roots Red Sea at the special JustGiving Page: www.justgiving.com/crowdfunding/rootsredseafundraiser
