You can call me a whimp, but that's more tanks than I would carry myself. I limit myself to two, unless I have a hand truck or cart.Yeah, my ex used to set up my gear, get it on me, take it off, put it in the water, etc but now that he's gone, I had to learn on my own, and Im carrying 2 tanks in each hand with another strapped into my BCD on my back.
