Has anyone got a suggestion on a portable GPS that will show the lake contour while getting to your spot? I would like one that I can mount on my snow machine or four wheeler. I bought a Garmin Colorado 400i last year and it'll show the islands, shoreline, roads around the lake but won't show the depths until you stop and mark it like a waypoint. I called Garmin support and they told me that there is no way to see the contours as you go, which to me makes this nearly useless as we search for the particular area we are targeting off hotmaps, etc... I am thinking of rigging my softwater Humminbird 595C combo with just a GPS receiver and mounting it to the snow machine but would like an easier out. I could also use use my chips if I go that route. Any input is appreciated.
