Rugged Stream Thermometer

Fly Fishing Thermometer


During the season, a stream thermometer can tell you when salmon will run. Salmon start to run at 30°F, at 40°F they will negotiate obstacles, but between 50/60°F they will be most active. Our indispensable fly fishing thermometer has a flat black metal housing for non-glare protection, a clip for attaching to your pocket, and a split ring for attaching to a lanyard or pin-on reel. Fly fishing thermometer measures both Fahrenheit and Centigrade.

    temperatures at all levels - 10/7/2014

    This thermometer can give accurate surface temperatures and you can attach it to your line for readings at different levels which is the best attribute. It is rugged but definitely not indestructible.

    Acceptable but not great - 10/7/2014

    I am very pro Orvis so I was a little surprised that the shell surrounding the thermometer was not quite up to the high standards that I have come to expect from Orvis products. Specifically there were some visible machining inconsistencies and finish blemishes. In addition the celcius side of the thermometer was more readable in the site window than the fahrenheit scale. Overall functional but not an exceptional Orvis product.

    Not Up to Orvis Standard - 8/25/2014
    By: from LaCrosse WI

    I was disappointed --- metal sheath that protects the thermometer has a screw top that unscrews on its own when attached to a the tether. I got lucky as a client saw it drop off the first time but the second time I wasn't as fortunate. Based on other reviews with similar issues I should have skipped Orvis this time but I didn't even bother reading them as it's such a simple item. My fault... But this is a product that I don't believe lives up to the Orvis standard.

    So far, so good. Tested it out in my fridge and glass of ice water. Seems to work fine.

    This little thermometer is both stylish and functional. Lightweiht, rugged and easy to read. I have an older thermometer but wanted to update it. This thing is dead on accurate. A must for matching the stream conditions to your fly.

    In a sturdy case, easy to read, accurate and fast. Great buy for the money. Don't fish for trout without it.

    Excellent Value - 4/9/2014

    This thermometer seems pretty well constructed. The price point really sweetened the deal and I think it is an excellent value. I put a tiny dab of blue loctite on the threads and that should help prevent any unwanted loosening of the aluminum housing of the thermometer.

    Works Great - 3/31/2014

    It doesn't weigh much, but it's rugged enough that I don't have to worry about it breaking in my vest.
