Dave,I actually started using this set on fall beaver.It will work any time of year.All you need is open water and beaver.In fall I like to be more on sign,as beaver arent traveling as much.In spring I will set them even when sign is not present.
I expect you to be in the front row at the FTA/Michigan convention in june.
LOL--that is the beauty part of this set,you dictate to the beaver--where you are going to catch them--not the other way around.If you have any open water now ,you should be slamming them with this set.
