I’ve used it on several river trips and it consistently gives accurate readings. The dual scale is helpful when I’m in a region that uses Celsius. It’s compact and doesn’t interfere with my gear.

Great tool for monitoring water conditions. I noticed trout were more active when the temperature was around 55°F, and this helped me time my casts better. Durable and reliable.
