The Inductosense ECHO is an extension cable designed to work with WAND sensors.
One end of the ECHO is applied over a pre-installed sensor (over the sensor coating), and the other end becomes the new data collection location. The ECHO is ideal for difficult-access locations such as underneath insulation, confined access, or at height.
The ECHO comes in a variety of set lengths, including 45cm, 100cm, 200cm and 400cm.
