Even tho i dont have a boat right now i bought a small Eagle 110?( i think thats the brand& model) a few mths ago( back in casper)..
It was only $15 marked down ( normaly$75) atwalmat -so i had to get it
Came with a free water temp guage to...but i havent tryed it out yet either.
My boat i no longer have

had a depth guage/ fish finder i putt on it( eagle brand to i think)( i did drill holes in my boat)- but that was 17 or so yrs ago& they have prob changed some since then?
