I've forgotten the brand name, but I have a wooden mouth rabbit distress call as well, and a hand held electronic that has several calls in it; don't think much of it though. About a week ago I went out with my friend for a couple of hours that picked up an electronic call with a remote control by Primus that sounded pretty good to me. We got verbal responses to a crying coyote puppy sound it has, but nothing came close to shoot in the limited time we tried, plus we got a late start. I think it has possibilities if we gave it a more serious go next time.
The best luck I have had though is just curling both hands/fingers together in a tube shape, and making long and loud as I can "kissing" sounds, LOL.
Winter is tough on whitetails, that is an accepted fact.
You can help the quality of your herd by providing winter plots - that are not necessarily designed as kill plots.
Having what I call green plots - that the deer can browse in when most of the other food is gone, can greatly benefit the deer herd when they need it most.
Come December - at least in our area of the south - most of the mast is gone, all of the crops were long harvested and this green browse can really make the difference for...
