Fishfinder? I don't fish.
You might call it a fishfinder. THe Garmin GPS 126 sounder does have little 'fish' icons and even a 'fish alarm' but I just use it to find the bottom and submerged debris. Mine's in a H23.5 but the ballast tank should be about the same. I could not find a way to get the sensor in front of the tank where it really should be and finally mounted it under the aft bunk. Get it pretty close to center. You can move the sensor around and try it by using KY Jelly to fill the voids. Pretty easy to clean up. Mine is permanently mounted with RTV and it can be removed with a razor blade if necessary. It works great down to 75' (deepest I've been in) and it finds fish, termoclines and tells a lot about the bottom quality. Actually, this Garmin is a fishermans delight, because you simply push the 'mark' button and can always return to that favorite fishing spot. Ken S/V Wouff Hong
