Suggested Upgrade: | Towed Fish Transducer |
Explanation: | Since there are a lot of people who want to build their own towed fish, it would be great to have SI transducers with extended connection cables. 50 meters would be perfect for a start! |

Hi there,
I built my own transducer and the trick is a very good shielded cable - CAT7 is perfect. My solution for the winching problem: Cannon Downrigger MAG20 ;) - I use two transducers with a y-cable - the one mounted on the boat hull gives me the "real" depth and feeds the downrigger - the one in the towfish gives me the sidescandata. In the beginning of the survey I just throw as much cable in the water as I will need for the depth - the downrigger goes up and down automatically and everything is fine.
The Towfish is just an aluminiumbody with the normal transducer attached to it.
Aquatically yours
