BTD-300 Thunderstrom Detector

Advanced standalone lightning warning system

The BTD-300 Thunderstorm Detector is a standalone sensor that reliably detects the presence of all forms of lightning to a range of 83 km.

The unique quasi electrostatic operating principle gives the detector a very low false alarm rate and the ability to warn of the risk of overhead lightning.


The basic sensor detects and ranges both cloud-to-cloud and cloud-to-ground lightning. The ability to reliably detect and range cloud-to-cloud lightning, which is typically much more common than cloud-to-ground strikes, makes the BTD-300 much more sensitive to the presence of storms compared to devices that rely on radio detection. As cloud-to-cloud lightning often precedes cloud-to-ground the sensor can give the user earlier warnings of lightning risk.

Features:

  • Warns of overhead lightning risk even before the first lightning discharge
  • Highly immune to radio interference which is the major cause of false alarms in traditional standalone detectors
  • 83 km detection range
  • Detects cloud-to-ground and as well as weaker but more common cloud-to-cloud lightning
  • Detects charged precipitation
  • Meets FAA performance requirements for aerodrome use
  • Optional direction finder
  • Virtually maintenance free
  • 2 years warranty
