I have a WT caller with the horn, the black box, walkie-talkie to communicate with the remote. Sounds are awesome, crisp, and clear. I also have a foxpro fx3. After my WT died last year, I took it apart to try and fix it. Once I fixed it, I recorded the sounds from it (they are on an sd card in the black box) over to my fx3. Occassionally I bring both callers and like them both. The WT sounds are definately a step above - and it still is my goto caller for coyote and rabbit sounds! Everytime I hit the pigmy cottontail distress I feel bad for that guy....lol
