Coghlan's Function Whistle

Whistle: Very loud. At first I was blowing on it too lightly and thought it was defective. I gave it a nice blow and wowza, yes it works great! Short bursts work well too. Compass: I'm completely new at using a compass but I do know west has to stay west and so forth. I've tried it many times in my house, I shook it hard many times and checked if the directions still pointed in the appropriate direction. It did for the most part, although it seems to be off by about a dash sometimes, but that could be me I guess. Thermometer: The print is small but my eyes for close-up objects is perfect so I have no problem reading this. For those of you who are far sighted, it may be a bit harder. I have no other thermometer to compare accuracy perfectly, but using my own bodies thermometer, it seems on point. When I turn off the AC in the house the temperature on this baby slowly increases and vice versa. The numbers that shown are by 10 values and the marked dashes in between are by 5 point values, plus an extra red dash for the 32 degree Fahrenheit. Magnifier: Its takes a tiny bit of effort to pull it out, but you can definitely do it no problem. Push it in from one end and use your nails to grasp it and swing it open from the other side. Or use a thin tool like a knife or small tool to push it all the way through. Usefulness: it's a little magnifier, it magnifies things a little. Other: The clasp itself is all plastic, no hinges. To open it wide enough to hang, you give it a push and it bends in somewhat. On it's own the clasp sits slightly ajar (1mm). It can attach to anything thicker than a millimeter and not fall out. I was going to give this four stars because the compass MAY be off by a dash, BUT that may be my lack of skill so in all fairness I won't take off a star. Also even if it IS off by a dash, I am backpacking trails so I don't need anything heavy duty, and if I did I would buy a compass on it's own. This little item is amazing! I bought it primarily for the whistle and thermometer and it meets my expectations. The compass is a plus and I don't care squat for the magnifier either way. The clasp is a simple plastic thing, it's thick, sturdy and will do it's job, I don't see that breaking anytime soon, It can also be replace by a tiny carabiner if you prefer. All in all 100% worth the money.

This clips on nicely to my backpack for when I travel. I like knowing the temperature when I am hiking and it is convenient for the direction as well. I haven't had to use the whistle yet.

I purchased this about 4 years ago and have been meaning to get more of them for my other backpacks. They are good quality and I don't think you will be sorry your bought one. Each family member should have one if you hunt or hike or like to walk in the woods. I just purchased 2 more just recently. I always have one on me when I go hunting or walking in the woods. The whistle is very loud and would think it will carry a good distance. The compass works extremely well, having used it a few time when I got turned around in the woods while hunting and always made it back to my Jeep. I find the Thermometer has come in handy while hunting many times. It appears to be quite accurate. I tested once with another thermometer and they both had the same reading. Haven't used the magnifier so can't comment on it. The clip is sturdy and hasn't broken even with heavy use. I am constantly moving if from my hunting vest to other things. That is why I bought additional ones so I don't have to remove it. These are great for the price and are nice gifts for your friends if they share your outdoor activities.

I've had two of these whistles since 2015 and both have held up spectacularly. The use has been moderate, tagging along for hikes and getting thrown about in a backpack for emergencies. It's rather rugged. The whistle is pretty loud, but you need to put effort into it. A light blow won't make any noise. A storm whistle is far more effective and won't get clogged with water. The compass is pretty accurate, I have compared it to a Suunto compass I use for maps and it's dead on, it's simply smaller so it can be harder to read and lacks any bearings. The thermometer works, and goes from 120F to -20F, but is quite small so detailed readings can be difficult. But works for general use. Finally the little magnifier is alright, I don't find it too useful. Tried to use it as a magnifying lens to start a fire but haven't had much luck with it. Maybe my review doesn't sound too reassuring, but like I said the cost and compactness and ruggedness make it very useful and easy to have everywhere or to have multiple. I've certainly used it on many occasions.

Bought this to attach to my life vest while kayak fishing. Lightweight and easy to read dial on the compass. It's accurate too. Haven't had to use the whistle, but it is loud enough to hear a long way if that day ever comes.

Really is a cool item in a small package. I magnifier actually works for starting a fire. The whistle is great for getting someones attention when at the back of a pack of ATV riders. The thermometer is just kind of cool but I dont think i need it to tell me its cold or hot out. The compass could be handy if a person knows how to use it or knows which way they need to go. Most aren't good with either and should go outside and practice with this kind of stuff so if NEEDED, a person knows how to use it. Learning to use these kind of tools when your in a bind is a bad bad bad idea. A person should learn how to use a compass and learn what can throw it off giving you a false reading, getting a person more lost than they were to begin with. I thought it would be a good idea to give one to my girlfriend when we went on a hike and after 30 minutes or so, I ask her to try to build a fire with it. After a bit of confusion and looking for fire starting material, then partnered with some patience and persistence, we had a small fire and she had alot of pride in her small accomplishment. But even more important, she knew she could start a fire if she needed to with this handy little tool, and proved it! I bought one and liked it well enough that I bought 4 more for my EDC kits I put together.

This whistle is a great addition to your hiking backpack, I strongly recommend for a safety feature. It’s very loud and effective and I love that it has a compass and thermometer included. I recently used it on a hiking trip and it was so loud that the Pika on the rocks were calling back at me, I think they didn’t appreciate how loud it was. Great price for a tool that can end up being lifesaving.

It's Ok for what it is , IT would work in a pinch I think it would work great for a younger person or even Boy Scouts be a good learning tool , everything works as advertised. The compus is a hair off, the magnifier will worth to start a fire,the thermometer works ok , it's an ok product. ...
