gregg,
My bad, I just realized that you don't have the FCV295 yet, and I just checked again. That R-509 will not work with the FCV292. :noway However, it will work with the FCV295, so it's something you might now have to consider.
These Pocket Transducers are normally used on commercial vessels, and these transducers have a housing that are designed to be flush mounted in an external void directly above the Hull or in the Keel.
And its recommend are that these types of transducers are mounted towards the front of the Boat near or around the second Bow wave.
