Anybody using gps Depth Finder Combo? If so how do you like it, cost, etc.? :-/

I don't have a combo but I really do like my Lowrance 3000MT GPS.  The variety of electronic maps I can make is awesome and the HotMaps from Navionics work like a charm.

I recently saw the new LCX-104 combo on a pros boat.  EXPENSIVE, but what an incredible display.

Make sure that you get a unit that will allow the usage of a contour chip to be place in it. The Lowrance model that has a 480x480 pixel count locator along with the GPS is great buy for the money. They are black and white, but they do a good job both mapping and charting the bottom. Go the extra mile to get the Navionics chip and you are really set up to fish unfamiliar and large bodies of water without wasting lots of time.

I have the Lowrance X-15 MT with MapCreate mounted on the consol of my Ranger.  My only complaint:  I didn't order one for the front!

This unit is absolutely awesome.  The depthfinder has excellent detail, and the GPS is very accurate (used it to mark underwater stickups last year during practice and was able pinpoint my casting right on target during the tournament).  In addition, being the techie I am, I use the MMC cards for creating custom maps, waypoints, routes, etc. before ever launching the boat.  Sure saves a lot of fishing time!
