chickdiver:Heh- I once had one try to tell me I could not dive without a "console". It was amusing as I was using an analog SPG and a wrist mounted bottom time and compass.......
It's always good to have a consol. If you get a leg cramp, they can be effectively used as a paddle...especially those great big ones!
Thay can be used as a drag anchor.
When put on the ehd of a hose that is 40 inches or longer in length they even make a fair weapon.
