Rated 1 out of 5 by sonny am taking this unit back.
not at all satified with this fish finder. will return it after trying every thing to get a good
picture. Way too much clutter and when reducing gain, can hardly see structure,
would not show fish, no matter what setting. Tried setting it to default mode and
still not good.

picked this baby up 2 weeks ago and I love it. had it installed in about an hour. more than happy with it. so many features that it takes some getting used too but outside of that its worth every penny. buy it you wont regret it

Rated 5 out of 5 by Garland Great Fishfinder/GPS Combo
I purchased a 581i HD DI Fish Finder/GPS fron Dick's in May and it is a great unit at a great price. Down imaging is a useful feature as are the many other options on this black and white unit. And Humminbird hits a home run when it comes to customer service and satisfaction. One word of caution - the black and white unit does not load Navionics gold cards in spite of Navionics assurances that the Gold is compatible because this unit lacks the memory of other 500 series color units and will hang up. No big deal, just check with Humminbird customer service before you buy a card - the Navionics premium product works fine I'm told, but pick your product and run it by Humminbird. If you want to go for the Gold, upgrade to the 597 color unit - more bucks but also a killer unit.
