I picked up a camera off of ebay. It is waterproof to 150' and had 60' of cable. Paid less than $80 and that included shipping. The camera is about 3" long and about 1 1/2" in diameter. Hooked it up to a 12v battery and bought a b&w 12v tv of $20. You have to build a couple of stabilizers which is no big deal. I attach a couple of cannon ball sinkers to it (wt. dependent on water speed).

works great. Only problem, you spend your time watching underwater tv instead of fishing... smile
