I am curious if anyone has tried one the various Chinese digital callers that have shown up on Ebay and Amazon in the last year or two. The prices on them have fell quickly to the point of almost being disposable after one season. Since they come with a USB cord I assume you can upload sounds and it appears they connect to a 12v seal lead acid battery for power.
I have never tried it, but I suppose that the issue of prices is due to the demand, the truth would call my attention to buy them and try them to see if they work for my purposes, the grademiners.com will look for them and buy very soon to see how they are, I hope that they are good.
