Description
Please also check out my latest design, a Long Range Dog Whistle at 7,000 Hz. Please download here.  | I have also developed real Ultrasonic dog whistles at 20,000 Hz and above, which you can find here.  |
WARNING:
This is an emergency whistle and not a toy! It's extremely loud which can harm the ears, so please protect your ears and don't use it near other people or animals!
Summary:
This time I was looking for a new emergency whistle and again couldn't find anything that suited my needs. So I made my own, and these are the main benefits:
- it is exceptionally loud,
- it is very sturdy,
- it has an ergonomically shaped flat mouthpiece that ensures a proper lip closure,
- it can easily be used hands-free,
- it has a double tone that increases audibility,
- it can be operated softly or loudly depending on the strength of the blow,
- it has a large eyelet suitable for thick straps and even small carabiners,
- it is easy and relatively fast to print, only requires 7 grams of filament.
There are 2 versions with different lanyard eyelets, see the last picture above.
