How R U on basic hand signals?

[Jax]

Let's all go to DAN at Alert Diver Online

Let your opinion of the Loser hand signal be known!

DON'T forget to applaud the basic test, though! It's kind of cool! :cool3:

The article in Alert Diver magazine mentioned the problem of hand signal dialects. For example, a clenched fist to a commercial or military diver means stop or hold — following the conventions for directing crane operators. Apparently some cave divers use it for OK while DAN thinks holding a fist to the chest means “Low on Air”. I see it all the time combined with slapping the bicep with the other hand that indicates something entirely different.

In the real world, two handed signals are useless. Holding tools, cameras, or downlines in a current make them impractical. Alert Diver’s warning to make sure you are all on the same page is the best part of the article.

Does anyone know where the cave divers use "hold" clenched fist as an "okay"?

As for the fist on the chest - NAUI and PADI say it's low on air.

both my daughter and I scored 14/15, thought the "L" sign was a silly trick question.

How do you test your blood sugar underwater?

With a sea urchin.

I have never seen "OK" with a clenched fist while cave diving. It usually means "stop/ halt" or "danger". In cave "OK" is most often done by making a circular pattern with your light beam around someone's light beam, or an "OK" with the fingers in normal fashion, in front of the light (just don't blind your team member, it pisses them off).

I have also never seen the "Low blood sugar" signal & missed that one.

Well not that I have many dives under my belt I did get the 14/15 as well. The "loser" hand signal was new to me and by reading these posts even our more seasoned divers agree. I'm still calling a "loser" a "loser" with the "L" on the forhead (between friends).

YMCA taught that meaning too back in the day...
