From the Jetboots site:

"Jetboots are designed to withstand anything you throw at them, whether it
is deep cave penetration or a large scale search and rescue operation. A
comfortable detachable battery pack can be used for dives anywhere between
the surface and 130 foot depth. For deeper operations a hard battery pack
straps on to the tank. This hard pack and a small modification to the
cabling allows operation to depths in excess of 300 feet."

I know we have many experts on the list.  Could the person or people who
performed "deep cave penetration or a large scale search and rescue
operation" please post their glowing testimonial(s) for all of us to see?
Or perhaps the manufacturer could do this.

Could someone tell me where to buy the dual calf mount adapters for my
scooters?  For what this thing costs i could buy two Gavins or three Makos
and just strap them to my legs.

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.
