The Lowrance XOG is a great value. Hands down the best bang for the buck for Sledding, Boating(not fishing), & Auto, IMO.
My comment was mainly directed a Mr. Ubee's inquiry about lake use. The XOG does not have track smoothing, like the larger Lowrance units, that allows it to bread crumb at low speeds when using the trolling motor.
I stand corrected, Polarisrider1, about the trail overlays. Your Lowrance download changed the base map so the overlay works. I had thought of doing that too, but having the Topo and Lakemaster lake contours (below water topo) displayed simultaneously would be way too much information to view. Switching between the gpssledmaps full version and Lakemaster chips, depending upon what I'm doing, keeps things uncluttered.
Garmins sunlight viewable screen is a plus too. The XOG washes out when in direct sunlight. Not a problem on the sled. Either hold your hand over the screen or turn a little so the sun isn't shining directly on it. This can be a problem when working a feature on the lake during open water.
For Sledding, General boating, and Auto use, the XOG has the rest beat, dollar for dollar. Except for a couple minor "hair spitting" issues outlined above and in previous post.
The XOG is water resistant. Many Garmins can be totally dunked and still be fine. Don't dunk an XOG. Especially with the power cord plugged in.
We all have to come to a balance of "what we can live with" and how much to spend for things "we can't live without". Cheers
