It can be dispensed in bursts which allows you to control how much scent is released at one time. Or, it can be dispensed all at one time, filling the entire hunting area with the best competition scent available! The nozzle atomizes the bomb as it is released into the hunting area. Atomizing allows the bombs to stick to vegetation in the environment so you can leave an active scent trail. Use the Rutting Bomb as a high testosterone whitetail scent. Use the EverCalm Bomb as a calming scent for herding in deer.
