Guideline Stream Thermometer

A compact and durable Stream Thermometer designed to help anglers make informed decisions on the water. Featuring a protective metal casing and attachment ring for a lanyard, it offers a simple and reliable way to monitor water temperatures and fish responsibly.

Monitoring water temperature is a key factor in responsible fly fishing, especially during warmer periods when fish are under increased stress. The Guideline Stream Thermometer gives you instant insight into water conditions, helping you avoid unnecessary strain on fish and make better decisions about when and where to fish. For trout, water temperatures above approximately 18–20°C (64–68°F) can become critical. In such conditions, minimizing handling or choosing not to fish at all is often the most responsible approach. With this thermometer, you always have the information needed to act accordingly.

The thermometer is housed in a durable metal casing to protect it from impacts and rough use on the water. A small ring at the top allows secure attachment to a lanyard or gear, keeping it easily accessible while wading or moving between spots. With a clear and easy-to-read scale ranging from 0 to 40°C, it delivers quick and reliable readings in Celsius. Its compact size makes it a natural addition to any vest, pack or accessory setup.
