AcmeThunderer Whistle 60.5, Small, High, Loud

Much louder than those backpack buckle whistles.Both the backpack whistle and this one were audible at 1/4 mile. This whistle was imo 70dB while the backpack whistle was around 55dB at that range. Just my opinion from experience with dB. Still want to test this at ranges of up to 1 mile & possible 1.5 miles.Pros:-First time you blow this thing hard (tongue blocking air hole - then quickly remove) - you will likely hurt your ears. I learned the hard way. Just a warning.... it can be loud with assertive blows.-blowing takes minimal lung capacity (I have Asthma)Cons:-I have extremely sensitive ears (yes I hear most electronics & nearly all tvs and chargers)----> Meaning I had to cut the metal keyfob ring out and replace it with rope to avoid excess noise----> hole was too small for 5040H paracord - likely could be drilled out----> used neon yellow mason line instead-Was whistling in a PA state forest this past weekend around people & it did not seem to immediately grab their attention or piss them off. I want a whistle where people instinctively are like: "OMG WHAT IS GOING ON?! SOMEONE COULD BE LOST - LET'S FIND THEM!!" Having said that I was approx. 100ft from said individuals & my hiking partners were laughing. It could've been the vibe.I encourage you to test every part of your survival equipment. I will likely fail to post back after further testing unless the whistle spontaneously combusts. Apologies in advance.

I loved the whistles. Worked great as expected. Used for Drum Major tryouts and performances. The Ultimate of Drum Major whistles.

This was a big hit with the beach lifeguards in my household.

A great tool. I immediately realized that it is at a much higher level than conventional whistles. It is very loud and robust. I'm sure it will last me for many years.

I have fond memories of using an Acme Thunderer as a lifeguard in the late 60's. It was effective then and is just as effective now except that I use it in my backcountry emergency pack, not the local swimming pool.

Works great. It's loud and distinctive. My only complaint is that the chrome started flaking off relatively quickly. This doesn't affect the function, but mine doesn't look nice and shiny anymore.

I had this same whistle from the 1980’s and gave it to my sone when he was the drum major for the University of Wisconsin… I got the urge to buy another and they are still the same quality and loud… yes, I would recommend this whistle.

My mother had one of these when she was a school teacher calling her class in from recess. She always had one at home for use with annoying solicitation callers and obscene phone calls. I have a particular company that my deceased fiance' did business with and they would not leave me alone no matter how many times I told them he was deceased and that I want interested in buying anything. They bothered me multiple times a week for over 4 years. Because they were not in the U.S they were not subject to no call list laws. It only took 2 times blowing this into my phone to get them to stop calling.
