I am planning on buying a FCV-295 fish finder and want to equip it with a CHIRP transducer. I have run across the B265LH and B275LH as candidates for this combination. Are there other Furuno transducers I should be looking at and is there a particular model that is high functioning with this fish finder. I have a 44ft wooden commercial fishing vessel. Running speed is between 7 and 8 knots, fishing speed between 2 and 3 knots, fishing depth between 10 and 70 fathoms.
