I am selling my Trek Wing for $125. It has been used on less than 10 dives. I dive steel 80s and its a bit too much wing for my single tank. Would be a great wing for single larger tanks or light-weight doubles. It has 45# of lift and comes with the gusset control system. This is a 2008 closeout model from Dive Rite. I bought a Travel EXP wing which best suits my single tank diving and would like to sell the Trek.
