The Heated Hunting Scents Dispenser can be hung on a tree branch or be placed right on the ground. The high performance threads ensure the scent will not leak and keep the batteries dry. The weather resistant switch can perform in nearly any environment with an LED that indicates on/off. Yet when the batteries are low on power and not able to generate heat in the required range the intelligent LED light turns off. In addition this is the indicator that to let the hunter know to recharge or replace the batteries on the next hunt. The heater will still produce low heat around 50F for two hours once the light goes outs. Operates on 4 AA batteries (not included).
