yes to all of the abovecaseybird:One might want to remain in contact with your buddy. One might also not want to blow out his eardrums while blasting past 50' at warp speed. One might not care about a last chance equipment check on the surface. However since you might tell me you always:
dive solo;
equalize perfectly;
check everything before you leave the boat;
This doesn't apply to your diving.
Good luck
My buddy's name is AL and he is never move than 3" from my side, has a zero air consumption rate, and is always ready to provide me with extra gas.
