The alarm mine is designed to protect gates, property, paths and areas of ground.

If the object or a trip-wire is moved, the mine will fire the 12 bore blank cartridge, giving a very loud alarm.

Can be used for airsoft or paintball ~ with permissions obtained first.

Designed to use 12 gauge short saluting blanks ~ so not to accept standard live cartridges.

Warning signs would be recommended.

Positioning of the alarm is important.

There is risk of tripping, eardrum damage, etc, if installed incorrectly.

One mine weighs 300 grams.

Option to add 10 x blank saluting 12g cartridges at the same time at a reduced price.

Three Small Red Blank Shotgun Shells

For the trip wire, a suitable strength clear fishing line is ideal.
