Current State & Issues Bow and arrow hunting is a popular

outdoor activity. An animal fatally shot with an arrow may not drop in place

Injured animals can travel substantial distances, may be difficult to track

Game which has been shot and cannot be found leads to more animal deaths and inefficient hunting

Desired State Wildlife tracking device will be deployed

with shot arrow and detach upon impact Allows a bow hunter to track fleeing target

using handheld device Does not negatively impact the accuracy of

the hunter’s shot Durable and reusable, with long lasting

power source Leads to less wasteful animal deaths in

bow hunting

Project Deliverables Re-attachable tracking device that

connects onto an arrow Handheld device that monitors the location

of the tracking device

Use Scenarios Attaches to wildlife and tracks the location

of it Misses wildlife and tracks location of arrow
