Diver skips predive check and finds his tank is empty.
My wife and I were on a two-tank twilight/night dive. On the night dive, my wife, who is a new diver, entered the water first. I geared up quickly, checked my regulator and BCD inflator but failed to check my submersible pressure gauge (SPG). I entered the water, and the group (led by a divemaster) quickly descended. The divemaster swam off toward the spot where the group would watch the manta rays. I brought up the rear of the pack, since I descended more slowly. My wife was about 30 feet ahead of me.
