I found this in a rubbish bin and bought it home it was too good to leave there. I have some spare domes to build another one. It is for sale at the right price. It would be good for underwater inspections as it could be set up to take video of the dive, cheaper than a diver and stay there longer. The previous owner told me it cost in the region of $100,000 to build as it was built for depths of 90 feet. It needs control systems to work the motors that are twelve volts. The metal parts are aluminum. The domes are about 300mm diameter.It has four motors.. cheers Stewart
