BlueWolf Posted September 8, 2014 Report Share Posted September 8, 2014 I don't think phone speakers aren't really good with loud sounds, let alone sound at high frequency. Especially outdoors. Though I have to admit I haven't tried it myself. Which app are you referring to? Quote Link to comment Share on other sites More sharing options...
Maz51 Posted September 13, 2014 Report Share Posted September 13, 2014 I have a 'Thunder' whistle..(used on boats and at sea for finding people - attached to luff jackets). Take care - very loud and can hurt ears!! Chester hears it v well..but...recall even in enclosed areas doesn't always happen every time... However it certainly grabs his attention if I go hide and call! Use at home to start...and call until they associate both for same reason. ☺ Sent from my SM-G900F using Tapatalk Quote Link to comment Share on other sites More sharing options...
