Following events at Stoney Cove and Vobster last year, and Capernwray just last week, the next Try Tech will be expanded to four days over the Bank Holiday on 25-28 May at the National Diving and Activity Centre at Chepstow.

The weekend is for divers from all agencies to find out more about rebreather diving – from the units themselves and how they work, to the costs and training required, and giving it a go themselves with one of the BSAC Tech Team. Plus, already-trained CCR divers can have a go on other units. Rebreather units available for the sessions include AP, Poseidon, Liberty and Red Bare.

The event is an opportunity for like-minded divers to get together and discuss all things technical, enjoy BBQs and evening tech talks. You can also take part in four-day technical training courses with BSAC. Divers can sign up for anything between half-day taster sessions up to four days for the technical training courses.
For more on Try Tech NDAC’s weekend programme and to book a session or SDC online, go to: www.bsac.com/trytechndac. The event is open to BSAC members and non-members who are Sports Diver (or equivalent) or above.

Is This The Best Dive Center Ever? W\@wakatobidiveresort

@sennacher
#askmark Hi there, regarding DSMBs. I’m no expert whatsoever and normally I deploy it correctly. This weekend we dove on very strong current and I almost lose my breath while deploying it (mouth inflate) as it tangled a bit on my reg. It scared the sh&t out of me so. Is there any “little cylinder” kind of thing in order to keep my reg in my mouth to deploy it safer? I haven’t tried to do it with my LPI… but asume it would tangle also.
Thanks

How Twinset Valves Work In Scuba Diving | Shutdown Drills And Isolator Tips Explained #scubadiving #askmark #twinset

Confused about how to use twinset valves or perform a proper valve shutdown drill? You’re not alone.

In this AskMark episode, Mark explains how valves work on twin cylinders, including how to safely open and close them, how isolator valves function, and why valve drills (also known as shutdown drills or V-Drills) are critical for diagnosing leaks during technical and recreational dives. Please visit our website for more Scuba news, underwater photography, hints & advice, and travel reports: https://divernet.com/

Mark also shares tips on muscle memory for reaching your left and right posts, isolator-first vs isolator-last logic, and how to prevent over-tightening or unsafe valve positioning. This guide is perfect for divers transitioning to twinsets, sidemount divers curious about manifold setups, or anyone wanting to improve their gas management skills.

Let us know in the comments how your instructor taught valve drills and don’t forget to leave your questions using #AskMark to get featured in a future video.

How Do Valves Work on Twin Cylinders? #askmark
@mostafametwally1
#askmark hi Mark. Could you do a video on how to deal with the valves and manifold on twin cylinders. It’s confusing to remember which way to open the valves and it’s easy to get wrong particularly in emergencies. Thanks

The photos are from the Capernwray event though… So maybe the first line ought to read “Following events at Stoney Cove and Vobster last year and Capernwray just last week”
