It should work okay for HF Chirp, if you can wire it up properly to a 10 pin connection for the GP1971F. Because sometimes the temp sensor is different from other OEMs, I recommend you speak with Gemeco (Tech support for Airmar) to see if the temp sensor in the model you have will work for you. Although it is better to purchase transducers on the compatibility list, if you are adapting from something existing, this should work fine once wired up as long as it has good hull placement. If you are getting turbulence, there isn't a fix for that unless you relocate it.
