• easy-to-read LCD display measures spurious hazards from background to extreme levels
• oversized numeric meter easily switchable from microsieverts to millirem or count per minute scales
• realistic digital counter from 0.10 μSv/h to 100 μSv/h (0.01 mrem/h to 10 mrem/h)
• authentic audio click rate, easily mutable for library or classroom use
• versatile alpha, beta, and gamma modes
• dual tilt-sensitive and touch-sensitive controls
• audio synchronized iPhone camera flash adds to the tension


1. Hold Digital Geiger Counter flat and face up.

2. Smoothly tilt Digital Geiger Counter's face to the left or right on the x-axis to increase levels.

3. Surreptitiously touch and hold the yellowish radiation symbol on the bottom left of the screen with your thumb to boost levels if necessary. The outside circle edge gives minimal boost, slowly increasing to maximum boost in the bottom left hand corner of the screen.

4. For best results with Digital Geiger Counter, practice subtly combining both tilt and touch control methods. Also try twisting Digital Geiger Counter as you move it towards your target. Be slow and smooth.


Digital Geiger Counter is meant for entertainment purposes only and is entirely ineffective at detecting actual ionizing radiation. Digital Geiger Counter is factory-calibrated to the x-axis and contains no user-serviceable parts.
