Insect hatches and fish feeding habits are greatly affected by water flows and temperature. As a result, a thermometer can mean the difference between a productive day on the water or getting skunked.

Equipped with a rugged aluminum case to protect the thermometer and a retractor/lanyard attachment to keep the thermometer handy. This easy-to-read fishing tool reads water temperatures from 20° to 120° F. Assorted colors (sorry, no choice).
