BisleyAlarm Myn

Arrived very quickly. Very well made.

I have everything from the hand grenade tops to the fith ops brand. in my opinion Bisley makes the best. I say this because I have used all the others and made my own. The triggering is a washer type with a notch cut out, it slips right into the shaft and it does not hang up, get bent, fail to go off. I don't like the couter pin triggers they tend to get stuck, when this happens it lets the knucklehead feel the line and stop moving. It also has a solid way to mount. I tend to use Kevlar fishing line black or camo in color. mono fishing line is to stretchy. wire is great but I don't want to find it. A cat set it off to n the video.

Oh hell yeah I use as an igniter for the big surprise

A very simple and effective design. It only has one movable part so reliability should not be an issue. The only problem i see long term might be corrosion but a little forethought (I'm thinking Froglube et. al.,) prior to installation should prevent that.I did polish the sear washer's contact surface with a stone and it helped sensitivity significantly.If you want/need such a device, i can highly recommend this one.

These are kind of Overkill unless you have to set them up at a great distance from you. They are well-made but big, bulky and heavy. Let's not forget they are pretty pricey.
