Why these select sounds? They have worked for Douglas in Alaska, Idaho, Montana, Wyoming and Washington. We are pretty confident they will work for you too! When upgraded through an in-app purchase, you will have access to all 25+ minutes of high quality audio recordings, with the ability to loop any individual Set indefinitely. Pick your favorite background image to customize the App from 5 pre-selected images taken in the field. The App supports the use of a bluetooth speaker (if you have one) to play the Sets at a distance from your location in addition to using the speakers on your phone directly. Supports a 'dark mode' that will reduce the brightness of the screen, reducing any light pollution that might otherwise be a problem in a low light situation.
