A fly fishing shop gave me about 100m of dacron backing for free. It's smoother than sewing thread. It needs to be able to slide along objects with minimal resistance.
I think sewing thread will catch.

There is Spiderwire for that price but i thats the sea fishing version
I bought this while back, price has gone up to R159 for 100m 10 or 15lb. Its fresh water braid and works nice for rigs.

I would think that cotton would stretch too much for this purpose and might not pop the pin. I dont have this device but am definitely looking :)
Have them set up. The fly reel backing didn't work, so just put it up at the main pressure points.
Feels VERY specops, though. Especially seeing the device at night :g:
Most cords that have some stretch will give ample warning before being triggered. Especially at extended distances. I had a 30m perimeter that I wanted to cover and installed 2 units for this. Most of the cords that I tried had to much stretch and I was able to get about 10-15cm of movement on a straight string, straight not taught. I would recommend something like electric fence cable or something a little thinner. even the thin wire (bind draad) would probably work better than cord. Fishing trace should do a great job but would be expensive.
I'll never forget the look on the guys face that unknowingly set one of these off right next to himself at our workshop after I had to go straight to a job in the morning and I forgot to remind my right hand man to disarm them :) I made it back just in time to hear alot of swearing and something mentioned about unions and the ccma right after the sharp bang , I suppose me just about passing out from laughter didn't help the cause but I can definitely vouch for the effectiveness of this device once triggered .
