Every one has a different idea which is nice to read as we can take, leave or try different ideas from others and form our own procedures. Heres my take
The marten in this area will climb I get refusals everyonce in a while from a few that do not.
When I 1st recieved a trail camera it put it to use right away taking pictures of how the marten worked a set- vertical vs horizontal.Since then its not very often I set vertical.
I make all my horizontal sets very easy for them to access,leaning poles.horizontal stick past the face of the boz etc.The other thing I do is large boxes to hold large amounts of bait,10 lbs or more is the norm.To a marten this represents a huge windfall. The walkers will climb then!Keeps them around and working that set.Sooner or later they get caught.Lots of times I do not use any other scent.
Larger baits also will have a marten working the bait while another is hanging in that 120.
If a storm blows in with a big dump of snow and you cant run the traps that hanging marten is good for a long time before anything gets around to eating it.
Only draw back is you have to haul large amounts until your boxes are full.The wolverine also like that bait too and can and will make a mess.These pictures have been posted before. Some anyway
