Loud, clear, crisp, omnidirectional, & penetrating are descriptors for the high pitch 109dB pea-less 'Mini' whistle, from Fox40. The choice of must-be-heard 'whistleblowers’ worldwide for both safety & sports.
The authentic 'Mini' whistle is one of two original 3-chamber ‘Pea-less’ whistles developed by Fortron Inc. (Fort, for Joe Forte - Ron, for Ronald Foxcroft) under the Fox40 brand name (Fox, for Foxcroft - 40, for Forte.) The patent was filed in 1987.
The 'Mini' was designed for use by professional sports officials (referees) to be heard above the din of ambient noises. The 'Classic' is the other. The lower tone 2-chamber 'Pearl' arrived to market in 1995.
**The very same no-moving parts whistle design for pro-sports has since proven superior,with outdoor/waterborne survival specialists and recreational enthusiasts as a premier safety whistle. This is where Ascent came in to help develop the safety market with Fortron. Since 1989, Ascent has marketed and sold the 'Classic,' the 'Mini,' and the 'Pearl' (1995) pea-less whistles.
Self-clearing multi-chamber flow-through signalling device designed to be heard, located, and not fail. Canadian made in ABS plastic.
