OK, I bought a Cuda 242 Fish Finder, (I bought what  I could afford).  However, the temp is always at 72 degrees.  It never changes, is there something I can do before I call the factory to possibly reset it??  Or is this a factory default?  I have not abused it or banged it around and the my boat is trailered, so there is no issue of it getting drug on the boat ramp or anything.  It has done this since day one, that I have used it.

Any ideas??????

Fishbear not to be smart $ or anything but is the unit in demo mode?

I know mine in demo reads 72 degrees also. :

ummmmmmmmmmmmmmm I am not sure,, but am going to check now... man am I gonna feel reaaaaaaaalllllllll stupid if it is........... :-[ :-[
