Good fish finder?

[Fish-Dog]

I've had a Raytheon 365 for 3 years, It has speed, temp, & distance, you can disable any of them if you want. I can pick up a swedish pimple and ratfinkee with a wax worm down to about 50' most of the time, however sometimes it won't pick them up. I think it has something to do with the clarity of the water. I take it off the boat in winter for ice fishing. The puck will not hang straight without some jury rigging. Last week it died on me, it still works however I have to reset to default every time I turn it on. Does anyone out there know where to get it fixed locally?
