Mostly curious about transducer going to CHIRP in addition to my "P66". My understanding is the transducer for my 585 will work as the CW version in these two fish finders. I am interested in trying a CHIRP but wonder about the improvement I would get. Most use is salmon suspended in 25-200 ft of water of up to 400ft depth. I'd rather not spend $1K or more on a CHIRP transom mount. Will the TM150 work for me and will it be a noticeable improvement over what I saw with the P66 on my 585? BTW I did try search function and didnt find any posts recommending the TM150 as an inexpensive way to go CHIRP.
