Hello, the only thing that has deterred me from considering tech is the weight. I am kind of petite (5'4", 120 lbs) and have enough of a hard time with a normal tank (I am in Miami so I most often time warm weather), and can't imagine the weight of a double tank, especially trying to climb back up on a boat after a dive (or two). Is this a normal concern and how do other women get around it? Of course, more squats in the gym, but I have spoke to several about smaller tank configuration, etc. but wondering what you all do.... with kind regards
Remember that it is all weightless under water.
I have done tech dives with women smaller than you. That includes women putting double tanks on their backs. Some of them, however, use side mounted doubles. The woman with whom I do my cave diving in Mexico is significantly smaller than you, and she is a side mounted diver. The first time I dived with her, though, she was back mounted. When I had some health issues prior to a trip, she offered to carry my doubles down to the dive site for me if I was having trouble. My pride was not going to let that happen!
See if a shop near you offers anything like an introduction to doubles pool session. Give it a try!
