Guitar strings. The ones that are just wire. Never did it. Just a thought

About 20 years ago I was given a rat snare and cedar stake for an ole timer Tom Brown. He was using rat snares back in the 30s. I asked him why he used them back then? He replied I use them on the feed beds where the water is too shallow to use a drowning set and conis was not around yet. As Newt stated they are the best dryland tool. I use them on my muskrat control jobs on retention ponds in complexes, where the den holes are deep. and the rats are grazing on the green grass. People walking by do not see the little snare set there and I give them enough cable to swim with a duck decoy weight on it if the water is deep enough to take them down. Also can be used on floats instead of a foot trap.

But wouldn't a 110 BG be more efficient? Especially a 110 sized RBG

Not necessarily if you have to catch rats on dry land. I get a lot of avoidance on rats with exposed traps if I have to set dry.

That's true to a point. But what happens when the rat doesn't go to water? And I can see them wrapping up around the support. I'm a fur trapper and I don't see for rats being trapper or rat friendly.
In a tight grassy trail I have caught a good share of rats In 160s.

I cannot remember, I would have to dig through things, but seems Newt had a pretty good DVD on snaring muskrats and mink.

Snood system of snaring by Raymond Thompson is about snaring rats

I still use snares for rats in suburban areas one because there cheap two because there almost invisible unless you know where they are located

It’s been my experience that rats go down pretty fast in a snare because there is seldom much evidence of struggle
