Airmar P79 Transducer (thu hull) installation

pvantienen

Hey gang, another newbie question here. I have a 97 Rinker Captiva 232 CC and I am installing a Garmin GPS unit. It has a thu hull transducer (not a whole, but through the fiberglass). I am thinking the best location for the transducer is below the front of the engine. (the factory one is there). Because this is shooting through the hull the install manual says the following:

The fiberglass hull below the transducer must be solid. Since the

hull absorbs acoustic energy, transmitting through the hull

reduces the transducer’s performance. Fiberglass hulls are often

reinforced in places for added strength or to reduce weight. These

cored areas contain balsa wood or structural foam which are poor

sound conductors. Do not locate the transducer over coring

Is this true below the engine on my boat?

Hi, looking at the complete instruction of the P79 it has really nice tips about deciding where to install it and even how to test the area of the installation. I don't know if you already had a look at his link but it is worth it. http://www.airmartechnology.com/uploads/InstallGuide/17-217-01.pdf Good luck Paul

I would be tempted to put the boat in the water and hold the transducer at various spots inside the hull and see what the imagine looks like.  Just a thought.

Good advice...thanks. Guess I will have to wait until I can get the boat in the water.
