Boltek Lightning Detection Systems

Whether you need long range lightning detection or high accuracy short range detection, we have the products and accessories to get you started. All of our products are designed for easy installation, along with free software updates that are always available from our website.

Short Range Systems

Our short range lightning detector systems have a very high accuracy up to 24 miles away and constantly monitors the electrical field of the atmosphere for preemptive notification of nearby lightning strikes.

With the optional ERL-10 programmable
Relay Output Module for the EFM-100
(and optionally the LD-250) you can
connect signal lighting or audible devices
to alert of incoming lightning activity.

Long Range Systems

Our line up of long range lightning detectors provide detection up to 300 miles away with directionality for tracking far off and close by storm movement. They can be used on their own, or make a perfect compliment to our short range detector.

Lightning archive files are created automatically
and may be played back at a later date.

Lightning strikes displayed within milliseconds
of detection.

Advanced storm tracking to determine path
of storm.

Customizable visual and audio alerts of heavy
storm activity or nearby lightning strikes.
