I have one and have only one complaint. It does loose signal sometimes Other than that... Sonar works great and GPS will put you within three ft if you have the area zoom to the max. The maps load fast... I wish I would have spent the hundred and got color. You may be just as happty with the X15MT. That used to be about a grand and now you can find them for half. Bigger screen and you wont miss the xtra watts. I don't fish to 1500 ft either.
