Sun CompanyOutsider - 4-in-1 Survival Multi-Tool | Compass, Thermometer, Whistle, and Fire Starter in a Compact Zipper Pull | Outdoor Gadget for Backpacking, Camping, or Survival Situations

The absolute best thermometer i have, and i have several. Usually the thermometers are about 5 degrees off when they are cheap. Not this one, it's absolutely spot on to a single degree.

Very well constructed except for the whistle which lost the block - shaped part with sun logo on first use and wasn't effective to begin with. I wanted a zipper pull with thermometer and compass so the Firestarter was a bonus. I will be buying a couple more for my snow jackets and I will bring a different whistle and still be satisfied.If not for the whistle I would have had to give it 5 stars.

The thermometer was tested in two separate freezers and two separate refrigerators to assess operating temperatures. I'm satisfied it gave me reliable readings, after which it conformed to room temperature readings inside my home taken from another unit. It is quite sensitive to the heat of your hand. Compass is very small and will get hung up if not level. The ferro rod and the striker are quite small for my large hands. One could easily fumble and lose the striker in the field. The whistle operates with gentle blowing only, not strong or hard. It's a nice little backup for the glove box of the car or attached to a jacket zipper on a hike. It's not meant to be a primary.

... but there are tiny caveats. I'm thinking 3.5 stars, btw. Note the size in the pic. It actually IS the size they claim, but if you don't think about it, it shows up smaller than expected; at least to me. I bought this because when I'm sitting in a parking lot and GPS says go East, I don't know which way that is till I start driving and it detects what direction I'm going. Everyone deals with this and it's obviously no big deal. The fact that it also includes a thermometer, whistle, and firestarter sold me. The flint & steel make sparks easily, cool. My car tells me the external temperature, so now I can compare to internal, cool. The compass was the main reason to buy this, and the steel stored inside throws off the compass, so you have to take it apart and pull out the striker every time you need the compass to be accurate. Not a dealbreaker, but c'mon, seriously poor design, as much as I'm a damn fanboy for multi-use gadgets. I'll just keep that out and somewhere handy, since it's only for in my car, but this is definitely NOT a survival tool. Still worth the money though, at least for my odd use for it.

compass does not work. barely a spark with the fire rod. whistle not very load. waste on money

Keep it on backpack since it has so many possible useful tools.Can start a fire with rod easily and the build quality is good for something this small.Good for gift for kids as wellWOuld buy again

My bad for buying this silly thing. The whistle doesn’t work unless you are trying to signal someone 2 feet away. And the firestarter? NO ONE is going to use that thing even if they forgot a lighter. Getting a fire going with flint and steel requires skills that virtually no one has.

It’s a handy tool if you need a fire! My husband started one for us with it! I like to know the temperature outside too. I like the whistle feature and compass too if I were to need them.
