Hey there, new to the sight and havent crow hunted in years! Now that duck seasons closing ive still got the itch to shoot some birds so I pulled out my crow calls and decoys. I lost my charger to my electronic call so I went and bought one from radioshack. After letting it charge for two hours my call woudnt turn on unless it was plugged in, So Im guessing I need a new battery... But im ready to get back into it!!
