Thread: Garmin handheld GPS units - need help

Have been looking at getting a decent unit for myself and had narrowed it down to the garmin 66st, until I started reading about the rino 750. Which seems to be much the same in terms of mapping, and setting tracks and waypoints on the unit and computer, the Birdseye satellite stuff but also has the uhf radio capability. Which when I hunt with my old man we use radios anyway so would save having another thing to carry. I guess what I'm really asking is have I overlooked anything in terms of the mapping side of things?
Cheers for your time and input 👍
