If the standard cord microphone is not currently working due to excessive ambient noise, high winds, or extremely low belt span frequencies, then the optional Inductive Sensor would be the attachment you would want to use. As opposed to the Microphone on both the Cord and Flexible Sensors which work on sound waves, the Inductive Sensor utilizes magnets attached to the belt to measure the span frequency wand therefore is not affected by wind or noise.
The part numbers for these additional attachements are:
- Flat Flexible Sensor: 7420-0205
- Inductive Sensor: 7420-0212
