There's also light signals for OOA that you can use which is just a wildly flashing light. In fact, given the viz and light conditions that we often run into a lot of the time it makes more sense to throw the light signal OOA on a buddy than the hand signal for OOA. If you're on a night dive at 100 fsw in the puget sound you usually won't be able to see a hand signal OOA from even 10 feet..GillyWeed wrote:That's assuming that they are actually looking at you to see the OOA which is the case with me when my buddy is 20' away it means he is NOT paying attention.. OR you have to take in to consideration that you can even see your buddy at all 20'.. We are diving in the Puget Sound right? I like the idea of throwing it on my sometimes less than attentive buddy..If your buddy is 20 feet away from you, throw an OOA on them...It might teach him a lesson... hmmm. Still need a pony bottle though just for the fact that I do dive sometimes with a guy that has mild ADD..
This then leads you to want good light discipline so that you're not constantly thinking that your buddy is OOA though..
