I've had a Hummingbird portable fish finder for at least 20 years. It's been reliable in all seasons.
Last week, I went out in the -40 degree weather and when I tried it this week, my screen had no display.
The lantern batteries still tested well (I tried them in flashlights) and the machine would beep, but there was nothing on the screen.
Worth fixing (and where)? Or it owes me nothing after that long and time for a replacement?
Thoughts?
Thanks.
