If you would like to make the Barker Horn your Ringtone (crazy) here are the files.
I have never added a ringtone, you will have to find what works for your device on the internet.
Warning-this may get peoples attention, but, not everyone is a boat nerd and may react differently!
Save this Barker Horn File m4r file to your phone.
Save the Barker Horn File mp3 to your device and create Ringtone
