Probably not a bad location
A good transducer location should satisfy the following criteria:1) it should remain submerged regardless of heel or pitch of the boat2) it should have good acoustic coupling with the water, i.e., hull laminate should be solid in that area, with no core or hull liner3) it should be accessibleThat being said, the area under the V-berth sounds good because it's low down and ahead of the keel. It's only out of the water when the boat charges off the top of a wave, but even then that's only momentary.You can check acoustic coupling quickly and easily with a Ziploc bag partially filled with water. Set the transducer on it, power up, then move it around on the inside of the hull until you have a return signal on the display that matches what you get when you hang the transducer over the side. This is important if you're in an area with a very soft mud bottom, otherwise you may spend the whole day racking your brain trying to get a good signal when in fact there is no way to get one. Don't ask me how I know this....For the record, I installed mine under the starboard settee next to the leading edge of the keel, but that's only because I didn't feel like wedging my massive bulk upside down in the V-berth. Good luck with the installation.PeterH23 "Raven"
