I think they are the same... However, it is a dated compass, I think I bought it when it was actually called a "GPS compass" because it has the little round circles to tell you how close you are given that SA was turned on. Based on the scale and GPS coordinates, you would mark your position and use the circles to give you a rough estimate of your worst case scenario. It's kind of moot now though. I can only guess the "AR" that REI uses is for Adventure Racing, cause it includes a UTM grid. All Adv. races I've done used UTM for the orienteering. However, there are better UTM grids than one stuck on the compass, it's better to have a dedicated UTM grid that is much easier to use to mark orienteering or topo maps with.
