Sun Company ChillChek - Waterproof Thermometer with Breakaway Lanyard | Water Proof Temperature Gauge for Swimming, Diving, Snorkeling, Fishing, or Camping | Small Portable Outdoor Thermometer

Very accurate tool. It's compact size with no dependence on a battery system. Is a trusted temperature monitor for travel medication carry.

The good news is that it’s small. The bad news is that it is too small. You can only read temperatures with an accuracy of 5 degrees. That’s practically useless.

Temperature measurement marks are set at increments of 5. If you’re trying to measure something more specific this is not the thermometer for you. (I ended up needing to know temperature to the exact degree or two. I learned that certain fish will bite at 52°, but virtually disappear when the water temp measures 53°.) Good thermometer if you do not need specific temp (for example if the water is in the upper 50’s vs lower 60’s). Thermometer was waterproof and compact.

I bought this to attach to my float for cold water swimming. It works as advertised! As it is very small, and my eyes are over 50 years old, it's a little hard to read when you're bobbing out in the water, and because it is small the gradient is very chunky, so it's hard to tell if the water is 50, 51, 52, etc... but when the water is that cold, it doesn't matter that much! It's cold!

Since my initial review, the seller offered a refund. I believe this shows the seller is honest and stands behind their products. Will order from this seller again Way too small to use while in the water, or after I hold it.

It didn’t work from the start-always read 80-never changed and was very hard to read. Non returnable item.

Easy to use, definitely water proof, compact and light for active people. 5 degree +- accuracy

Should've sent this back. It's really too tiny to see without very strong glasses or a magnifying glass!!

プレゼント用として購入 商品は自分で7年間 使っている。

Biggest waste of money I’ve ever spent. Suppose the cord is decent

デジタルは極低温では機能しない物ばかり アナログの物も購入したが極低温の山に持って行ったら針の動きが安定しなくなり正確性に欠けるので、水銀温度計がやはり安定してて良い 水銀なので破損した時の事を考えると持ち歩くのは？といっても気温の確認には正確性と安定性からこれがコンパクト、シンプルで良い

正確性はどうなのか有ったら便利だと思います
