We are proud to announce that we are an authorized distributor of Boltek Lightning Detection Systems.

StormTracker does not have self-test or fault detection circuitry and is not intended or recommended as a primary means of detecting threatening lightning. There will be some degree of error with any single antenna lightning detection system.

There are pros and cons to using a Boltek Lighting Detection System that we want you to be aware of before you make your purchase:

• No Recurring Subscription Fees. The national networks that are out there have very expensive recurring fees for their data.
• With any single antenna system, there will be some degree of error. Accuracy becomes better with optional 3rd party software and as storms get closer to your location.
• Lightning strikes are instantly received.
• All products have a 1 year warranty and 30 day return policy.
• Some installation is required:
  • Mount the antenna. Typically mounted 10-20 feet above the ground, away from large metal objects and sources of electrical noise such as televisions or computer monitors. (LD-250 and StormTracker models only)
  • Open your PC and insert the PCI StormTracker card. (StormTracker model only)
  • Install the software
