The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
I am debating on what is best thermometer to get for measuring stream temperatures. I looked at a couple of older threads on other forums and there wasn't anything clear cut. Some are using cheap kitchen-type thermometers, some are using the mercury stick-type thermometers made specifically for use in streams and lakes and others are using more expensive digital thermometers. Any suggestions?
