World War II–Era Code Machine Recovered from Baltic Sea - Archaeology Magazine SCHLESWIG-HOLSTEIN, GERMANY—According to a report in The Guardian, a team of World Wildlife Fund divers looking for abandoned fishing nets in the Bay of Gelting found a N**i Enigma encryption machine resting on the sea floor. Naval historian Jann Witt of the German Naval Association thinks the ma...

Gareth does a nice job of describing the "Four Stages of Psychological Safety". Stage 4 or challenger safety, is where the statement "anyone can thumb a dive at anytime" fits.

Here at DRDS we have been discussing ways to make diving better and more safe as we stay home through the pandemic. One of the thoughts we had was changing that statement. Yes, we can all thumb a dive but how many of us actually do? It is an inactive statement meaning that we can thumb it but we are not active in finding reasons to thumb it.

I personally (Turk speaking) have been on two dives I should have thumbed. One I did not thumb due to feeling I was unable to "challenge the status quo without retribution, reprisal or the risk of damaging their own personal reputation or credibility." I did choose to challenge that post-dive and was talked down to and made to feel as if I was inferior and incapable of tech diving. This is not how anyone should be made to feel from an instructor or dive buddy.

This brings up a good question we would like to pose to you. Rather than stating we can all thumb a dive, should we make it more of an active statement? As we gear up, plan and throughout the dive, should we ask "Is there a reason to thumb this dive?" This changes things a bit and makes each team member actively look for reasons to thumb the dive. Only when we can't find a reason do we continue with the dive.

If you have a team of three and each team member is looking for reasons to call the dive does this make us safer and help to eliminate the "challenger safety" ? You tell us?

How Safe is Your Diving? There is a need to manage safety in diving - this normally consists of managing active or physical risks like DCS, out of gas and entanglement, but what about something potentially more important?

Nice piece on why we need to standardize our cylinder markings. The only part I disagree with is that all extra money should be sent to the "Turk wants to go to Bikini" fund but all in all, a great piece.

What are your thoughts and how do you prefer to mark your cylinders?

Don’t MOD your Percentages - SDI | TDI | ERDI | PFI This is a topic where not all parties agree, but all could benefit from a unified stance. Marking your cylinders for the type of dive you’re doing. This not only helps you do your final predive checks, but it also helps you stay safe and keep your buddies safe as well.

Situational Awareness

Cristina Zenato and Kewin Lorenzo are based in the Bahamas. The islands have been in total lockdown again for five consecutive weeks.. This means no work can take place for these guys, no diving ..not even a trip to the beach. Tough times .. So lets show them some support..

Check out the People of the Water site….People of the Water is a non profit organization dedicated to change people's relationship with our aquatic world through exploration, education and conservation. This includes cave exploration and collecting information about sharks. Please consider making a small donation so the great work can continue as lockdown eases.

Very well thought out article by Mark Powell on dive planning.

We use TTS when we plan CCR dives and are now looking into it for OC dives as well. What are your thoughts on TTS and min gas rather than a set bottom time?

Evolution of Dive Planning - Shearwater Research Plan the dive and dive the plan has long been the mantra employed in all areas of diving. Technical divers, in particular, spend more time planning their dives than many recreational divers. This is due […]
