First ,check to see if you have a jawspread limitation in your state.That will dictate what traps you can use on land.
I agree with worm on the old square jawed victors,better for boat anchors than for canines--also a very bad trap on coon.
Brkshires will hold a moose,attach by using a j hook and swivel to the end of your trap chain.If you have a lot of rust on your traps,wire brush the heavy stuff off,then dye.
Waxing sppedup and protects your trap from more rusting.The wax also locks the dye onto your trap.
You want the shortest drop possible before your trap fires,squaring of the dog and dog notch helps a lot .
There are a lot of good traps out there,here again it depends on jaw size,Dukes and Montanas are just a couple more,especially for more budget minded trappers.
More questions--fire away.
