Bowhunting physics simulator

The Archer’s Toxograph

Model what happens between release and impact: sound arrival, aerodynamic speed loss, compensated trajectory, and the animal’s available movement window.

Wind along shot mph

Positive wind travels from hunter toward target; negative wind is a headwind. The same component affects sound and arrow-relative airspeed.

Use measured launch speed instead of estimating

Model presets use manufacturer-published IBO/ATA speed and brace height, with a 70 lb / 30 in starting setup when supported. IBO/ATA is not hunting-arrow speed; confirm your module, actual draw weight, and chronographed speed whenever possible.

Preset shaft GPI and outside diameter follow published specifications. Included hardware is used where its weight is published; vane weights remain practical estimates. Measure your actual cut length, components, finished mass, and chronographed speed whenever possible.

This is a transparent movement proxy—not a biological prediction. Real deer lower their center of mass by joint flexion and loading, not by becoming a freely falling object.

Compatibility check

Screening only. Confirm the exact shaft in its manufacturer spine selector and verify broadhead, rest, nock, and full-draw clearance with a qualified bow technician.

Sound and arrow leave together; response begins only after sound arrival plus latency.

Tree-stand shot geometry

The tree height and ground range form the legs of a right triangle; the sloped line of sight is its hypotenuse.

Use this as a comparison and education tool, not an ethical-shot guarantee. Drag coefficient and animal response are the largest modeled uncertainties. Verify launch speed with a chronograph, use your actual finished arrow, and choose distances based on field accuracy and local hunting rules.
