Wanting to start trapping

[justwannano]

1 1/2 coil spring traps will catch all of your target animals.

I buy used equipment and have found that wire strechers are plentiful but you have to watch out for rust. One of the little things that can ruin fur.
I paint rusty strechers. Its hard to hurt a wire strecher.
Wood ,on the other hand, can crack and warp and I don't think you get the air circulation that I think is needed.
However I do use wood for mink.
Buy strechers designed for your target animal.
Best of luck.
