Just wondering what you all use for dive gear in the warm water. Full face mask? What do you find most affective in under water recovery why, how come and how many people do you use? This would be a great help for me and my crew when we train. We use 2 man groups and use the 1.5 viz patern it seams to be the most affective way to do it in the New England waters. Just looking for all your input.I also have a hard time training new members in fresh water lakes and ponds it takes me 3 times longer to train them why?. Any input would help me out.
