Triplespool and Hiawatha.

You guys have come to the right place to look for info, but there is a reason you aren't getting the responses you are looking for. Help with calling is a little vague first off. What exactly are you having problems with? Howling, distress calls, electronic calls.. if you ask a more spcific question about calling we'll all do our best to help.

As far as my advice, pay careful attention to setting up quietly and use good camo and some sort of cover to break up your out line. Wait a few minutes before you start calling, and only call for 1 to 2 mnutes at a time, trying hard to really sound like a wounded critter, putting some emotion into the call. Then wait, perfectly motionless for a few minutes, then try again. Give it 20 minutes or so, then pack up and try a new spot.

2 pieces of advice I have heard that helped me become more successful. You can expect only 1 out of every 5 set ups to call something in .. so knowing that, regardless of whether you saw an animal .. just KNOW that something comes in and checks you out 1 out of every 5 times, so be alert and hopefully not get busted. This year with the snow here in the Northeast I have been circling my calling location after I have unsuccessfuly called and looked for fresh tracks in the snow, and I would say I am only seeing about 1/2 the animals that are approaching the call.
Second is have LOTS of land! If you keep trying in the same spots with the same results.. you've got to try new areas.

Hope that helps.
