I've made and purchased ALOT of trip wire mines and pressure mines over the last 10 years.
Marker Setup:
BT-4 Combat, Archon hopper, remote line.
Strengths:
Small, lightweight, very fast set-up, incredible coverage, very sensitive, low profile.
Weaknesses:
I really can't think of any weaknesses.
Review:
I've had two of these mines for at least 3 years and I use them ALOT. They are by far the best mine made for paintball. I've been designing and building paintball mines for 10 years and still haven't seen anything that beats them. Any bad reviews you see on this mine are by people that didn't know how to use them properly. These mines blast out a wall of paint you just can't avoid.
For proper performance....
1. Aim the blast tubes up at a 45 degree angle and away from center at 10-15 degrees.
2. Do not leave the caps on the blast tubes.
3. The tripwire has to seperate from the mine instantly upon detonation.
4. The draw string has to be unobstructed when the mine is detonated.
The price on some sites is way too high. If you look you can find this mine for $35.00.
I figured out how to make this mine with parts from the hardware store for $10.00.
Conclusion:
If you're looking for a tripmine for paintball this mine can't be beat. I highly recommend it. I've never had one of these get set-off without eliminating the target.
