The Convergent Hunting Bullet HP Bluetooth Game Call was designed to be very rugged, plenty loud, exceptionally clear, and easy to use in conjunction with the Convergent Hunting Solutions Mobile Applications. The Bullet HP has a working range of up to 300ft, 10 times the distance of standard Bluetooth. It uses an integrated internal lithium ion battery which will last all day and is rechargeable so there is no need to ever purchase batteries. It has a built-in decoy controllable via the app. The decoy features dual directional, erratic movement that has proven very effective in triggering responses from even the most suspicious predators. Simply pair the Bullet HP with any Android or IOS device and launch one of Convergent Hunting Solution's mobile apps, and you are ready to hunt. Because it is connected to your mobile device via Bluetooth, you can play your own sounds, even your favorite music!
