Garmin Intelliducer - Transom Mount-gctid811786

[vwmusky1963]

I recently purchased a used Garmin GPS chartplotter from a friend of friend and found out that it's a NMEA 2000 unit. As such, it looks like I need to purchase a transducer that is NMEA compliant in order for it to communicate. I checked into what was available, and of course, experienced sticker shock! The in hull (not thru-hull) NMEA transducer is $400+ (2x as much as I paid for the Garmin unit)! After some surfing, I found a transom mount "Intelliducer" that should work for $100. In the past, with my older Garmin unit, I have taken a transom mount transducer and mounted (silicone) in the bottom of my bilge and everything worked great! Now question is this: Not knowing much about the NMEA compliant Intelliducer, can I do the same thing with it - Silicone it to the bottom of my bilge and run it to the "backbone, then to the back of the Garmin? Hopefully someone has experience with this and can help!

Welcome to the BOC. Have you called Garmin? My experience with their tech line has been very positive. They didn't ask how or where I bought the unit, just the model number, from there it was all about making me a happy customer. When we bought our 3818 with 1988 electronics, I called to get non sales information about what products I should be looking at for the lower helm with repeaters on the flying bridge. The techie explained how the NEMA 2000 works and that I can use my iPad as the repeater.

What model is your Garmin chartplotter. It may have a separate input for a transducer and a drop-cable connector for NMEA 2K. Check the back of the chartplotter and also its installation guide.

I have a new 12" Garmin and almost any Garmin transducer will work, mine has a 12 pin and an 8 pin transducer connection.

I am mounting my transom mounted transducer in the hull in a box with liquid until I can haul out and do a thru the hull mount.

The NEMA has to do with the NEMA port, I also have DVI and Ethernet (2) as well as video ports.
