I came across this older Impulse fishfinder (circa 1990) and wanted to come up with a canoe mount for it. The battery set up is 10 D-cells wired in series. They produced 16 volts out of the package, and the manual says the locator can run on 11 - 16 volts. After about 3 hours of constant use this weekend, they still read 15.57 volts, so I should be able to get a few days of a few hours each day use without changing batteries. I debated between something like this or using a 7 ah 12v lead acid battery that fits in a small ammo box. I like that all of this mounts to the thwart and will be smaller to pack.

I still need to clean it up a little by shortening the transducer cables and the pole on the transducer mount, but was happy with how it worked.

nice. How heavy is the set up?
What size PVC did you use?

Thanks. It's 1 1/4" PVC. The D cells fit almost perfectly without rattling. I haven't weighed it but the brackets are all aluminum. The batteries are obviously the heaviest part. (I would weigh it but don't have a small scale handy, lol).
