I have a New in box Convergent Hunting Solutions bullet electronic call. It is an all in one electronic call and decoy in one compact unit. It has internal lithium batteries that are rechargeable so there is caring extra batteries around with you. It works with a free app that you down load to your phone. Hate to have to sell it but I have to pay some bills. If you have any questions you can call or text me at 785-534-3438. Thanks Darrin
