Just went through a problem with my GPS module for my Lowrance 525c. I knew it had been hooked up right (a bit of a pain in itself). Did all the trouble shooting and took it to a dealer, who hooked it up to a store model.

Fortunately kept the receipt and was just under a year for the warranty. Once I found the number to the service dept (had to get it from the dealer, not a user friendly website) they were pretty helpful. Just sent it back on the 18th and was told it will be 4-6 weeks for the turnaround.

I really like the graphics and screen size. It is very easy to use for non-technical types. Keep a back up GPS in the boat though.... just in case.

For fishing Seiku, it is a good idea mainly because of the nasty sea fog that rolls in all weather.

Good Luck!!!
