Looking forward using while doing HAM radio

Took this with me to a local fair that had predicted showers in the area but there was no lighting in the area. I will carry this with me when ever we are out and the weather is prdeicted to have storms looming. Will be a great tool to have when doing HAM radio in the field.

AccuRite Portable Lightning Detector

Just had the opportunity to check the lightning detector in an office environment, as a thunderstorm rolled through. As long as the unit was near a window, it quickly registered strikes. I had to restart it a few times as it surpassed the 199 strikes level that the display has for an upper limit. Will see how it performs in a home setting next. So far, it's doing its job!

Excellent sensor!

The only check I have is the local weather forecast and observations, but this thing appears to be dead on.
