When fur was worth skinning, late 70's into the early 90's, except for the time away due to my job for a bit over 4 years, I had anywhere from 200 to 400 sets out during the entire trapping season. Was on a 24 hour check for everything back then. Averaged over 150 miles per day from the first of November to the end of February. Limit of 20 on raccoons back then, too....usually had that on the first half of the first check.
200-400 sets- thats' some serious trap line checking!!
Just depends on sign . If there is alot of sign. I may put in a flat set a deep dirt hole. And a type of pipe set. A blind set on the trail. And i like using snares too. The 2 bobcats was taken on public land. That is a duke 1 3/4 offset 4 coil. The coyote was on the hunting club. Duke 550 4 coil offset. All 3 deep pad catchs. Work your pan over. Short pan fall on 3 pds pan tension.
We run about 2-3 dozen at a time, including a few snares. Mostly for bobcats but some coyotes and beaver. Bridger #3, MB 550s, NBS K-9 extremes and a few Montana coil springs. The Wind River pan covers are great too.
