A fish-finder for the cockpit.


My previous boat had an open wheelhouse so it was easy to see the fish-finder when drifting. Rebel Runner has a bulkhead, so the fish-finder screen is out of sight. Having looked at the cost of a secondhand slave screen, I opted for an entry-level Garmin Striker 4 - less than £130 all in. One of the options was a foam transducer mount for inside the hull. At over £20 for a bit of foam, I thought I could do as well for less. I cut the bottom out of an electrical junction box and Sikaflexed it to the inside of the hull.


I cut some upholstery foam to the size of the box, then cut out a transducer shape in the foam. I filled the space with antifreeze liquid and pressed the transducer into place. This allows for adjustment to keep it vertical on a sloping hull, and there is no damage if I need to remove it. The wire is fed through a standard electrical grommet. Now I can see the fish on the drift!
