Merry Christmas and Welcome,
The Vista's have the electronic compass.
If you have the Legend HCx, you don't have a compass per se. It is only a direction/bearing indicator. AND you have to be MOVING, (at least a little) other wise it'll wander around aimlessly.
Walk north 20 to 30 ft and it should point that direction, turn right 90 degrees and within 5 or so ft. it should show you headed east.
If you do the 'bee dance' don't try to keep up the spinning arrow - you'll get seriously dizzy!!!
The "direction/bearing indicator" is acting like it's frozen. And so is the map. And when I walk 40+ feet it still doesn't work. With a very good satellite connection.
