Treestand / Angle-Shot Horizontal Distance
The horizontal distance to aim for on a steep elevated or depressed shot.
How this works
From an elevated treestand, a rangefinder measures the straight-line distance to the target, but an arrow's actual drop only depends on the horizontal distance it travels — the cosine rule converts one into the other. This is the same principle as the rifle Uphill/Downhill calculator, just scaled for typical treestand ranges and angles.
Why steep stands need this most
At a shallow angle the correction is small, but a steep treestand can put the true horizontal distance meaningfully shorter than the slant range shown on a rangefinder — aiming as if the target were at the slant distance is a common cause of high misses from elevated stands. Many rangefinders have an "angle intelligence" mode that does this correction automatically; this calculator is useful for checking that feature or working the math by hand.
Frequently asked questions
Why do I need the horizontal distance instead of the slant distance my rangefinder shows?
Gravity only acts on the true horizontal distance the arrow travels, not the slant distance — from a steep stand, the horizontal distance is meaningfully shorter, and aiming as if it were the slant distance is a common cause of high misses.
At what treestand height does this correction really start to matter?
The steeper the angle, the bigger the correction — a low stand with a shallow angle needs only a small adjustment, while a very high stand shooting nearly straight down can shrink the effective aiming distance substantially.
Does my rangefinder's "angle intelligence" mode already do this?
Many modern rangefinders include an automatic angle-compensation mode — check your specific model's manual, and use this calculator to verify the result if you're ever unsure whether that feature is active.
