I glued the transducer in hull and all I get is "---" readings on my display. Follow

Here is what you need to do:

1. Remove the transducer from inside the hull by placing a piece of wood against the hull and tapping the wood with a hammer until the transducer is broken free.  Click Here
2. Remove any adhesive from the transducer underside with sandpaper; don’t worry if you scratch it. The plastic is 1/8th of an inch thick and can be roughed up, just don’t gouge it.
3. With the craft in the water in depths over 15 feet deep and the unit turned on, hang the transducer over the side directly in the water with the transducer pointing towards the bottom.
4. If you have readings proceed to step 6.
5. If you do not get readings, place the transducer up to your ear, and listen for ticking from the transducer. If you don’t hear ticking check the connection to the depth sounder and also verify that the unit is turned on.  Still, no ticking, contact NMP customer service.
