Has anyone tried this or similar 12 ga trip alarm?
I do the same, although the model of alarm I have must be different as it has a 1/4 mile range and the base unit uses AA's and will run for about a week of battery power alone.The deer around here would set them off on a regular basis. Useless to use if you have larger animals in the area.
Instead we use infrared driveway alarms with rechargeable batteries with the furthest one about 160 yds from the house. And instead of having to use two secure points of attachment you only need a single attachment point.
I think a big difference would be not having any shot at all, possibly not even a plastic wad.what legally distinguishes (generally speaking, i am sure laws vary by locale) a perimeter alarm from a booby trap?
is it purely intent? or do some elements of design matter? it looks like for instance the designs shared do not have a chamber, meaning the shot inside (even if there were shot inside) would not be accelerated to a lethal velocity i would think. is that the big difference?
just as well, it would be cheaper to hand-load something that was just primer, shell, and powder.I think a big difference would be not having any shot at all, possibly not even a plastic wad.
If you hurt someone with one of these I would imagine it take a good lawyer($$$$) on your side to have a chance of it mattering that it was intended to be an alarm rather than a trap.
