I'm eyeing that FishHawk with envy, John.
My boat came with a Garmin 93SV (the older non UHD version) and a Lowrance Elite 7 Chirp. I seem to prefer the Garmin stuff but its hard for me not to wonder about the Humminbird gear. I figure these Big 3 all pretty much do the same things.
Congrats, UBDSLO1 on the new electronics. Hope it does the job for you.
Before you switch your Garmin's go to west marine and push buttons on units of interest I have a garmin 64cv the lake charts are awesome downfall no inland lakes
I mostly fish with the chart shows structure well
