I bought their original preditor call, two years ago. I took it on a float trip into the Brooks Range. My partner would not let me use it till the last day of the trip. The Fawn Bleat was the only thing I could get a response on. There is no Cayotes up there, only wolves. They did respond and come to the fawn bleat. The squelling rabbits, had no a affect on them. The Cayote howl also had no affect. After I got home back I did call in a Red Fox with the squelling jack rabbit.
When I returned I asked Cass Creek about making one for Moose Hunters. They did and I took it last year on a Moose hunt in the Alaska range. It worked good for calling Moose. I called in a bunch of young bulls, and several Cows, but was unable to bring in a Big Bull. Again my partner would not let me try the preditor call, he was afraid that it would scare off the Moose in the area. After our hunt I took the Preditor call out by myself. The Fawn Bleat did work for Bears, problem was all I got was sows with cubs.
I like the fact that they can be carried in your pocket. Or in the glove box on a snowmachine or 4 wheeler. I got the extra speaker, but have not tried it in the field yet. I intend to use them this spring for Preditors and Bears. My partner is so afraid I will bring in a Grizzly, he does not want to be around when I use the Preditor call.
