There are a couple tricks to setting this guy up

By DannyBoy

from St. Louis, MO


  • Don't have to pull the boat to install
  • So far, works like a charm, through the FG Hull


  • Does not adapt to the 43dv easily
  • Have to buy an additional adapter
  • Pretty sure cable is not 39 feet
  • Somewhat complex to install

Best Uses

  • In my houseboat's fiberglass hull

Comments about Garmin Airmar P79 Adjustable 200/50kHz Plastic In-hull Transducer 8-pin:

If you want to install a transducer inside the hull without pulling the boat you need this guy. It is a pain to get mounted level, ends up being a compromise. The directions tell you to make it level, and you can not have it level both side-to-side and fore and aft. Downloaded a really handy app on my cell phone which allowed me to tell how many degrees off level it was in both directions. Interesting that the final step before locking it in place is to pour propylene glycol antifreeze into the little pot you glue down in the bilge. (that is the pink stuff you winterize with) Unfortunately, I had the gadget installed and then discovered I needed an extra 10 feet of cable, and then discovered the cable is an 8 pin, and the Garmin 43dv wants a 4 pin plug... The adapter, West Marine part # 16361743 is available (that number is hard to find). Unfortunately, when I fired it up, it said the p79 in-hull transducer was shorted and to shut it down. Even more unfortunately, I first took the system at its word, figured it really was shorted, and ordered another transducer, because I needed it that week. Then I decided to call Garmin. The service guy said he had just found out from Garmin Engineering that you have to use the override option that was available when that message pops up. When you hit the override button, the 43dv warns you that you should only do the override with the p79 transducer. Once you do it, all is well. Used the unit this weekend, and it worked great... pretty sure that the chirp feature is not available with that particular transducer. Now I have to return the extra transducer.

Service and delivery comments:

I wish the guys in the store had known that I needed the adapter. And, I wish the adapter or the p79 instructions would have had a note that I would need to hit the override button... Would have saved a headache.

    Works well, if you have 4 pin input you will need adaptor as it has 8 pins
