Thanks for the link.
The cost of one of these is attractive to myself cause I could do a three way split with my Son & Son-in-Law.
We have three homemade prototypes using Mp3 player, voice recorders (that accept mp3 sounds) and a cheap Johnny Steward caller. All three of these use the Radio Shack mini amp.
The sound is good enough but I think that those boy's would jump at the chance to own something a little more professional than my clap-trap items even though they are portable.
Those boy's have commandeered these calls to date and that is fine with me because of the enjoyment that they get out of it and the possibility that they will break-in their own children to this sport.
I mainly use the mouth calls and actually prefer to do so. I have nothing against those tronics and have mainly been coaching those boys more on the importance of using some stealth when getting to the call site
And the setup itself. They used to think that I was crazy because I would abort a hunt at a site where they would slam the vehicle door or talk in normal tones even though they knew that we would be walking
For a way's. I Think that they are catching on.
