Years back, folks used light weight 'Coon drags' and light weight 'Coyote drags' with short chain with poor results. I had bad experiences of Coon climbing trees and never finding a Coyote while using light weight drags and short chain.
This left a bad feeling for most folks and many swore never to use drags again. But I 'needed drags' in some areas and experimented and talked with some pro trappers. What the problem was with the older style drag was they were too light with too short a chain.
A heavy drag and longer chain sloved alot of problems for me. I use a 2 lb.-3lb. drag with at least 6' of kinkless chain. I use 'em for Coon, Fox, Bobcat and Coyote. Catch is within sight.
Here's a few styles of drags I use....
L. to R. JC Conners drag, JC Conners swivel drag, homemade drag
at least 6' of kinkless chain..
Here's a large Coon, last season, on a drag hung up on cut Corn stalks.
Springhole set is between Corn and railroad in deep depression. Water runs slowly under railroad to other side where other traps are set in puddle. 4 to 5 traps (with drags attached) are set at this springhole location (both sides of railroad), plus 2 foothold traps in cornfield near Groundhog hole.
I have caught Reds, Greys, Coon and Coyotes in this springhole and holding them with drags...
