I purchased a new Humminbird GPS/Fishfinder Model 595C 2 years ago. When I recieved it and turned it on I had a black screen. I returned it to Humminbird, got a new indicator by serial number. Then the GPS didn't work. Returned it to Humminbird. Got a new GPS antenna by serial number. Then the indicator wouldn't accept the Navionics card. The GPS Screen would go blank. I returned it to Humminbird. Got a new indicator by serial number. Then the fish finder started to go from the current depth to 1010. Shut it off/Turn it on it was ok for awhile then back to 1010. Returned it and got a new indicator by serial number. Then my GPS went again. Returned it and got a new GPS antenna by serial number. Then It was fall of 2007 and time to put it to bed for the winter. WILL IT WORK THIS SPRING? Humminbird wouldn't refund my money because I bought it on line. It was too late to return it to the on line dealer. So for $500 I'm stuck with an iffy GPS/Fishfinder. If it works.

I hate to say it, But I have never met anyone that has had good luck with Hummingbird!
Throw it away and start over with a Garmin or something with a good name!

Good Luck!

I agree. I have had 2 Hummingbird GPS/Fishfinders. The fishfinder part is fine. The GPS always sucked. I finally got a Garmin GPS 172 Color in August 2006 and bingo no problems. I still use the Hummingbird but just as a fish/depth finder and temp gauge.

I figure I am better off not relying on one unit for everything anyway.

I had a gps/ff unit for three seasons with no problems, then last season the ff went. I sent it back to humminbird and they fixed it no charge. I still got a garmin combo unit though, I just don't trust the humminbird.

i had problems with my gps working after 1 season but they replaced it no problems.

Other than that I love it.

there, now you have met a happy humminbird customer :)
