While we have many sailboats that have successful glue-in installations, we definitely see the most customers' having difficulty with their installations due to:
- hull thickness, especially around the keel.
- limited installation space due to the keel
- fiberglass voids and/or unsaturated
When we have customers ask what type of transducer we recommend for a sailboat, we always tell them a thru-hull is by far the best application for most sailboats. You can exchange your transducer by clicking here.
If the unit reads hanging over the side you can be assured that the depth finder is functioning properly.
Things to look out for while testing your installation location(s) are:
- Any air pockets or voids will cause the sonar signal to fail.
- Make sure you are using enough petroleum jelly to make a good solid binding agent between the transducer face and the hull.
- We sell an upgraded glue-in transducer, but if you are not having success obtaining any readings, it probably won't solve your problem. Generally, it will only fix erratic readings and will not correct no reading situations.

- If you do get the depth finder to shoot thru the hull you must use a 2 part epoxy like this Or if you need it sooner most big box stores sell something like this.
