I have a Maxi 84 with Raymarine depth sounder.This instrument has worked fine for the last 2 years.Boat has been in the water all winter and it worked ok from Whitehills to Inverness over Easter.However it is now not bleeping when first powered up and gives a flashing reading of around 60 meteres instead of the correct depth.The word 'depth' at the top of the screen is no longer there and the increase/decrease in depth arrows are missing.
Anyone had a similar problem or does anyone know how to solve it.
