Subject: Airmar in hull transducer
In reply to: Dan M32 #36 Independence 's message, "thru hulls" on - Saturday - 02/ 7/09 - 2:47pm

I just installed an Airmar in-hull transducer. It was under $100, glued to the hull with a silcone sealant, and works great with my Garmin sounder and chartplotter. Here's the airmar link: http://www.airmartechnology.com/airmar2005/ex20/RMProducts/ElectCat.asp?ProdID=52&Man=All&PageNo=99

That being said, you may be able to use your old transducer with a new sounder. ...it depends on how old the transducer is. Most of them are dual frequency these days.

I don't see anywhere a spec for the thickness of hull it can pass through and worry when it says "good for racing sailboats up to 25'". Thin hulled little bastards! But you're using it, so all must be good, no? Where did you position it?

My issue is more w/the readouts. Either they have gotten smaller or my eyes are less strong, but at night I can barely make out what they're telling me. So it's time for an upgrade...at least in font size!

Anyone use the "new wireless" units?

Hi Randall. I mounted my transducer under the aft-most drawer in the port settee. It turned out that was the only place I could find a 22 degree or less deadrise angle (this model of transducer can mount on a surface with 0 - 22 degrees). From my understanding, hull thickness shouldn't really matter. Sonar signals have problems crossing boundaries between different types of material but shouldn't attenuate much based on the thickness of the fiberglass. So a thick solid fiberglass hull works fine but a thin cored hull wouldn't work.

My transducer is hooked into a garmin sounder box (gsd 22: https://buy.garmin.com/shop/shop.do?pID=288) and the sounder is hooked to a garmin 4208 chartplotter (https://buy.garmin.com/shop/shop.do?pID=8113). The 4208 also works as my radar display. You can display the depth soundings in a whole slew of different ways. The whole mess is also hooked up with my autopilot.

...I went a little nuts with the electronics. I like that stuff.
