Steel tank as pony bottle for Self Reliant Diver.

[happy-diver]

Yeah, we were slinging across our stomachs from 5l Fabers to Al 80s-90s 25 yrs ago what a mess
even with less stomach

Here the model is wearing a 3l steel auxilliary bottle, strapped to the right side, of a 15l steel main tank

View attachment 819762

see the model being dragged sideways by his auxilliary almost plummeting to the bottom of the ocean

Im concerned about failure points -im mean the shirt button has already come undone and is an entanglement hazard -are those cookie on the left shoulder strap? are you even cave trained?
