Our high-precision temperature sensor has been redesigned with a 26 mm (1″) bronze button on the front, providing a fast thermal time constant of 15 seconds, and now offers an accu racy of ±0.3 °C. Precision temperature data is transmitted to a probe, chart plotter, digital display, or computer. The unit is ideal for both recreational and commercial fishing, as it can detect thermal boundaries such as the edges of Gulf Stream currents. Show more
