What it does

Everything in the field. Nothing you don't need.

🎯

Precision Ballistic Solver

Full G1/G7 drag models with spin drift, Coriolis effect, atmospheric density altitude, and incline correction. Real physics — not a lookup table.

FIRST PRINCIPLES

🗺️

Tactical Map Layers

USGS TOPO, 3DEP LiDAR relief, 3D composite satellite, and BLM land ownership overlay. Know exactly what's public and what's private before you walk in.

BLM OWNERSHIP

📍

Hunt Waypoints

Drop GPS-precise sightings, stand locations, glassing points, water sources, and migration corridors. Long-press the map — it's that fast.

8 WAYPOINT TYPES

🔭

DOPE Cards & Truing

Generate printable holdover tables for any load. True your data against real observed impacts with DSF, MV, and Tall Target wizards.

TRUING WIZARDS

💨

Wind Risk Advisor

Live wind data from Open-Meteo layered against your shot geometry. Know when conditions exceed your hold capability before you shoot.

LIVE WEATHER

☀️

Sun & Glass Advisor

Know when the sun will be behind you, in your scope, or lighting up your target. Plan your glassing windows and shot windows by time of day.

SOLAR PLANNING

Land Ownership

Know where you can hunt before you hike in.

Toggle the BLM Surface Management Agency overlay on any map style — the same federal data layer used by onX Hunt, rendered free directly from government tile servers. No subscription required.
