I have used several models of the W.T.in the last ten or so years, dont believe everything you read , they will call critters as all e callers will , but they dont do a thing another brand wont do . there are several things i do not like about a w.t caller ,
1. no sound list or digital display of sounds on caller ( you have to make your own)
2.some models require two hands to operate the remote
3.some models are heavy and bulky
4.you cannot load or change the sound library on a w.t. they must be sent back to have it done and you will be charged for the service.
5. sounds are expensive.
6. short warranty .you never hear great storys on the internet about the outstanding customer service from W.T.
7. i wont post

as Carl said get on the predator calling sites and read up on the company and its owner.
