.22 Caliber Mini-Sentry Trip Wire Alarm

Effective 24/7 Security for Preppers and Survivalists

Mini Sentry

The Mini-Sentry trip wire alarm can be used to protect large areas or individual items. It can be used on pastures, fences, roads, gates, vehicles, equipment, tools, supplies and more. A distinct advantage to a trip wire alarm with the loud crack of a gun shot is the trespasser or thief knows that you are aware of their presence and location, and that you are serious about security.

The Mini-Sentry is tiny, easily concealed, uses a loud, readily available, inexpensive .22 caliber blank, is constructed of machined brass, galvanized and stainless steel and is coated in a flat black finish.

The Mini Sentry can be installed temporarily with a zip tie, string, tape or wire, and more permanently with screws For additional information on protecting your loved ones and property, go to this website.
