Yes, just look on you tube etc,.. Plenty of info out there.
It needs mounted in a very specific location, AND YOU WANT TO DO IT ONCE..
Best bet is (on aluminum boats anyway) install a teflon puck pad on the rear of the boat ONE TIME, TWO HEAVILY CAULKED SCREWS,.. Any future outer hull "in water" accessories mount to this pad vs penetrating the hull 15 times over. (Wish i had a link, i dont)
The unit you are looking at is a basic unit, IT HAS TEMP, your golden.
(Be ready for others to say you need a $600 HD unit, thats fine,.. There's tons of opinions on these units. I'm done with unnecessarily expensive gear. I'm looking for, depth, temp, thermocline, if it marks fish (or should i say air pockets ) great.. Still doesn't tell you what kind of fish (air pockets) its marking)
Keep it simple, heads up,... Look forward and keep on casting.
