Compact Lightning Detector
The SFD-300-HG is a dual-purpose compact lightning detector with 3 modes: Lightning Detection Mode, Stadium Mode, and OFF. When in Lightning Detection Mode, the detector provides visual alerts to approaching or departing storm fronts and lightning by sensing the distance of lightning strikes that are in the area, making you aware of potentially life-threatening situations.
Features:
- Portable compact design (lanyard & strap included for portability)
- Detects lightning up to 25 miles
- Compact design
- The same technology as used in expensive weather stations
- 3 different colors indicate the distance (approaching or departing) of the storm front:
- Green = 25 miles
- Blue = 16 miles
- Red = 6 miles
- High accuracy
- Sealing IP40 rating
- Dust proof enclosure
How It Works:
- When the detector is first powered on, the first three blinks of the center green LED indicate the unit is calibrating. Calibration takes a few seconds to complete.
- Calibration is complete when the second three blinks of the center LED flash green.
- The center LED flashes green once every 10 seconds to indicate the unit is listening for lightning.
- When lightning is first detected (up to 25 miles), the detector flashes all 5 LEDs for 1 minute.
- To save battery life, after 1 minute of lightning detection, the detector switches to blinking only 2 LEDs for two more minutes. After two minutes, the detector turns off.
- If a closer lightning strike is detected while the display is flashing, the color will change to indicate the distance of the strike.
- When the next strike is detected, the unit turns back on, remembers, and displays the correct lightning distance range (red, blue, or green depending on lightning distance).
- If another closer lightning strike is detected while the display is flashing, the LED color will change, but the 2-minute timer does not reset. The detector will turn off after two minutes. The 1-minute and 2-minute cycles then repeat.
