I picked up an ACME Tornado 2000 a couple of weeks ago. ACME claims it's the world's loudest whistle (122 decibels!?!) and I believe them. One short, split-second blast of air into this whistle and my ears ring for 30 minutes.
Mine arrived today from a strange Bee obsessed bloke http://www.edcsource.com/6x--Bright-Orange-Survival-Whistles--Flat-Vic-Style,name,103015,auction_id,auction_detailsThanks Neil (very nice man really!)
Tone wise they remind me of old police whistles, which is strange considering they look absolutely nothing like them
I had this titanium whistle custom made for me. It's 2-1/2" long with a ceramic glass breaker ball on the end. Enjoy!
Very nice mate. Is that Dave's handywork?
