- Fixed positioning / mapping (tracking where marks are relative to you). No Velocitek product can do this (yet), but it is only a matter of time before you have products like Deckman in better form factors then they are now. (FYI Deckman is what "the big boats use" to tell them distance to line, distance to layline, angles between marks, etc after they have inputed them into their nav comp).
Velocitk and Rock Box can both do distance (and time) to the start line. Rock Box can at least do distance and heading to marks maybe to laylines as well.
