heh heh heh, heheheh HAHAHAHA AAAAHHAHAHHAHAHAHA!!!!

sniff sniff... Christ, coffee all over the laptop.

Ben, you have absolutely no idea what we do around wrecks, do you? I won't
even comment on using this rig in a cave.

Seriously, a scooter has to be ditchable, you cannot strap batteries and
shit all over yourself like this and be in a technical environment. You will
wind up Muffatonied.

Good luck in recreational market, that should be no problem, those pinheads
on rec.scuba will buy anything.
