Yet another broken depth sounder

[MrsRobinson]

We are on our 3rd boat. I replaced the depth sounder in the first 2.

We've had our current boat since November. The Depth Sounder it came with worked inconsistently at first. 80+ degrees this weekend so a bunch of us went out and anchored overnight. The depth sounder is now blinking with what looks like a bunch of 8's.

I assume she is dead. It's a Lowrance 3500.

1 - Why do these things break so often?

2 - Should I replace the guage with another Lowrance 3500 guage? Or should I pull her out of the water and replace the thru hull transducer first?

3 - Is the Lowrance 3500 and good and reliable unit? The boat is 11 years old now and this looks to be the original.

Thanks,

Give Lowrance a call to see if the newer 3800

will accept your existing transducer.

BoatFix has the QT206 for about $25 less than Consumers. I don't know what you mean by the Navman Power series but here's a list of all the Navman depth gages:
