I use an Aqualung wrist computer with wireless air integration. I love having all of the information in one place - dive time, depth, NDL, air pressure and estimated gas time remaining. I have also used a hose integrated computer console that has all of the same information, but I prefer having it on my wrist. I generally dive with my arms in front of me, so for me it’s easier to glance down at the wrist mounted computer versus locate and read the console computer.
