USAGE: If you simply wish to play a call one time for testing purposes or if you wish to only play a call once, just press the big play button for each call (Simple Mode is also available). Otherwise, to get started with a time looped call press the text field and input your desired time, then press “Start Loop”. For example, if you input 50 into the text field and press “Start Loop”, the call will loop every 50 seconds unless you press “Stop Loop”. It is recommended to not mix more than 2-3 calls at a time. If you overly mix calls, it might scare away your target! It is recommended that you do a bit of research on the web about using Coyote, Predator, and Squirrel calls if you have no experience using calling techniques. CALL GROUPS: -Coyote and Fox Calls (16 Calls) -Rodent Calls (16 Calls) -Big Game Calls (16 Calls) -Bird Calls (16 Calls) -Squirrel Calls (8 Calls) It is recommended to use an external Bluetooth speaker(s) when using Predator and Squirrel Calls. Be sure you have your Bluetooth turned on and speaker connected if you use this app with Bluetooth speakers.
