For those who want flexibility from their Bear Sentry.
One expansion pack can increase the area protected by a Backcountry fence from 25 square meters to roughly 65 m2 (in a hexagonal layout).
Add more to outfit a group or camp with friends.
With two expansion packs you can set up a food or game cache away from your tent, which you can secure with the same energizer.
Because the Bear Sentry system is modular, you can use expansion packs to convert a Base Camp model into a Backcountry, and vice versa.
For extremely dry conditions, you can use at least one expansion pack to set up a positive-negative (ground-return) system.
