19mal71,
Furuno doesn't offer the "Q-ratings" for our transducers, it one of the "trade secrets" guidelines that tell me. I'm told that they do exist, and I've even tried to get that information to no avail.
However, I can tell you that Furuno "CA" Transducers are built to a very high quality, built to take punishment for use within world wide commercial fishing fleets.
Picking the right transducer for use with your fishery is the heart and soul of any fish finder system, including selecting the good location where to install it on the vessel. So it all comes to down to picking the right transducer based on the following criteria: Frequency, Power, Beam Width, and Construction.
Also, keep in mind that the FCV295/FCV1150 have the following frequencies "locked-out" 53-65kHz, 111-139kHz, 171-183kHz. So this can restrict use with certain CHIRP transducers, even if you plan on using them for single frequency use with the FCV295. So are you wanting to see fish just off the bottom, I'd select a single frequency transducer that is higher frequency and with a narrower beam angle...
