David- I see we have come to the sme conclusions over the years.
I usually blind set where the mink climbs out to eat its catch and sometimes get a double if there is more than one landing and feeding spot there.
Agreed.
Its a friendly arguemnt I have with my friend BK, who nowadays uses mostly BE sets.
Our debate is he will catch them underwater hunting...and I'll catch them AFTER te catch. Actually had one this year where a 10 inch or so brown was laying at the trap bed, and pulled up the wire to find a nice mink. Closer examination of the trout showed tooth marks behind the gills. Without a doubt- it was that mink's trout (well, 99.9% sure LOL).
I do do better with resting (landing) sets above deep water rather than below.
Another very good spot for both rats and mink- is at a bend, at the spot where something naturally drifts.
In other words- as an experiment- stand on a small creek where there is a curve and a drop a stick into te water. Watch where it goes. Where does it touch the bank, perhaps even "resting" briefly.
Mink and rats are bouyant, and will come through current to about the same area as that stick....
