RE: What trail markers to get???
Glad to hear it Doug. I actually picked up a newer Motorola model, the T7200, this past season as it is supposed to have slightly better range because of its design/features. After extensively trying it I still prefer the T6400 for a variety of reasons...some of which you already are familiar with.
As for the problems talking from one unit to the next, are you referring to from a non-Motorola unit to a Motorola unit or from one Motorola unit to another Motorola unit?
Sorry for getting off-track.
