The armory

Your whole kit, and the numbers behind it.

Log your rifles, bows, optics, stands and gear once. Antlr turns your zero and load into a ballistics card, warns you when a harness is due, and keeps track of who borrowed what.

Questions hunters ask

Straight answers, from your own numbers.

What’s my rifle’s drop at 300 yards?

It depends on your load, your zero and your sight height. Add them once and Antlr works out drop and wind at every distance, and whether to dial or hold.

Which pin do I use at 29 yards?

Add your bow’s pin gaps and arrow, and the card tells you which pin to use and what it really shoots like.

When should I replace my treestand harness?

Go by the maker’s replace-by date. The armory keeps each harness and lifeline’s date and reminds you before a sit. [Cite the industry guidance, with the date checked]

What make is my headlamp?

Take a photo. Antlr proposes the make and model from a catalog of thousands of hunting products, and you confirm it.
