MGRS
READY

Made for the field

Maps, land, and dope — close at hand.

Where am I? What kind of land is this? How far is that? TerraTac keeps map, grid, and ballistic planning in one place.

MGRS/UTM military grid
Live BLM/public-land status
G1/G7 ballistics with range rings
GPS track-back and night vision

Know the limits: Phone GNSS is typically ~5–30 m; compass readings can be affected by metal; ballistics are model estimates — confirm zero with live fire; land data is approximate — verify regulations.
