I bought a dozen pigtail snare supports and I'll be darned if I know how to use them. there must be something else that goes with them. would it be posible for someone to draw me a sketch of how to set it up ? thanks for any help.

A rebar stake (1/2") slide thru the coils. Slip that same stake thru the snare end swivel too and drive into ground at snare location.

I buy annealed "black" #9 wire and wrap my own, then it'll be welded to the stake where the vice grips are in my picture above. It's the very best snare support for supporting snares off the ground. Works great on killpoles too.

Here’s a vid, they’re pretty slick but I haven’t used em much yet.
On a side note, this is an older vid. After a lot more testing in the field, this Lightsout system is more effective with a short snare. You don’t want them running 10’ after the snare drops down. Entanglement is not something you want with them……..if you’re using these kill systems.
