This thermometer has been my go-to for checking water temps on the river. The screen is clear even in bright sunlight, and the aluminum probe doesn’t corrode after months of use. I’ve used it during cold and warm seasons, and it’s always accurate. The button to turn it on/off is easy to press and the device stays reliable in wet conditions.

Great tool for fly fishing. I appreciate the IPX7 rating — it survived a few drops in rain and a full submersion in a river. The screen is bright and easy to read. Battery lasts a few weeks, and I can replace it when needed. A little bulky for pocket carry, but worth it for accuracy.

I bought this after reading reviews and it’s exactly what I needed. It’s durable, accurate, and works perfectly in the field. The probe stays clean and doesn’t scratch the water surface. I use it every time I go fishing, and it helps me decide when to fish based on temperature.
