Fish finder help for float tube

Hey guys came across this fish finder on sale at bass pro. Humminbird PiranhaMax 175 Fishfinder Was curious if anyone has any reviews on it. I'm just getting started in tubing been out once and thought this would be cool. All help and info appreciated.

My fishing partner has this ff on his tube and after helping him set it up he really digs it
Works great and does everything a tube finder needs to do
I have a garmin Echo 150 on my odc 420 and love it but if I had to buy a replacement the p max 175 would for sure be on my list
It will work great considering the transducer is mounted in the correct position on the tube
Other than that buy one and go for it
