Other brands are an option. So is filling your tag.

A single button does the math. Just squeeze the trigger and remember your knife. Amazingly compact and simple to use, the Scout 1000 ARC figures distance based on terrain angle to give you an accurate "shoots-like" distance to 1,000 yards. Rifle Mode even tells you where to hold. With selectable Bow and Rifle Modes, it has the same capability some competitors need to split into two separate units. All with the tap of a button - in a vertical unit small enough to fit in your shirt pocket. In capability and ease of use, no one comes close to Bushnell.

Angle Range Compensation - ARC

Extreme up and downhill angles alter true horizontal distance to your target. ARC accounts for the terrain angle when calculating distance, so you know precisely how to shoot the range.
No guesswork. Just backstraps.
