If you like the Rino 520HCx and the Rino 530HCx, but don't see any need for a color display screen, rechargeable capability, or 5 Watt transmit power, you may want to look toward the Rino 130. This unit has a feature list as advanced as the Rino 530HCx with a much smaller price tag. It can tell you where you are, what direction you're going, the altitude you're at, and even if bad weather is approaching. No need to worry about getting lost in the woods, or getting separated from you're group. You've got a Garmin.
