I've learned that in no-stop open water diving, the thumb means "this dive is over". There may be many reasons for terminating a dive, and many of them don't preclude a safety stop. So, if I or my buddy thumbs the dive, we'll ascend to safety stop depth where there will be a short discussion (diver 1: flat palm downwards, three upright fingers below. Alternativey, "level off" followed by "3". If the other diver gives the thumb again, it's surface time. If the other buddy confirms the suggestion for a safety stop, then safety stop it is).
That's my impression, too. But I haven't had any "real" technical training, and the post I replied to was about a type of technical diving that I've only read and been told about.Is this not true for non no-stop diving too? Or, to avoid the double (triple?) negative, this is true for all diving.
If we - hypothetically - were to dive together, we'd need a pretty thorough pre-dive chat, because otherwise we'd have some serious communication issues.What I bolded above in your quote is the usual meaning accepted by all buddies (not my regular buddy) I've dove with. If we are below the safety stop depth the flat palm on top of three upright fingers means "I want to ascend and do a 3 minute safety stop". The thumbs up sign if it's below safety stop depth means "let's go up to a shallower depth". After the SS it means let's surface now. I've reinterpreted the two signs based on the NACD book and my regular buddies preferences. I haven't been very successful in getting my inst-buddies to accept these variations so I just go with the "standard" meanings for these signs.
Sorry somehow missed this.So if you went to do a half depth stop for a 25m dive, would you stay 3mins at 12m in addition to a stop at 6m ?
Are you feeling better because you just did a longer stop or because you did a deeper stop ?
I.e. would you feel even better if you doubled the time you stopped at 6m and didn’t stop at 12m ?
If you are still here after all the cave diving chest bashing...How do you make a deep stop hand signal?
For example, telling your dive buddy that you're going to a do a deep stop at certain depth for a certain duration.
question: in the recent study Mark did that’s referenced here, what was the depth of their first stop for the shallower stops?
Both the links a provided in reply to this post are about deep stops in dives with considerable deco stops, not ones with only safety stops. It is already difficult to draw conclusions between the NEDU study dives and ‘technical’ (ie recreational deco) dives.@DiveTucson Thank you. Would you please explain why you don't think it's appropriate? Or is there any theory to support not doing so?
