WHAT IS A ZAP CHECKER? 

©2002 Alan Broadband Co. 

The Zap Checker is an Ultra-Sensitive instrument that
detects and displays electromagnetic radiation over a broad spectrum of frequencies. 

I have tested my unit well beyond the listed range.  From 4.5-18 ghz! I was amazed at the sensitivity all the way up to 18 ghz. Even at 10' distance I could clearly see the needle movement and and indicator lights. 

 

      

 


Features of the Zap Checker
1. Easy to use. 

2. Convenient size: a small, lightweight hand-held instrument that fits into a pocket
or purse. 

3. Highly sensitive: Detecting radiated signals from cellular phones and phone bugs at more than 20 feet, transmissions from "sealed" microwave ovens at 40+ feet, from FRS walkie-talkies at 60+ feet, and from ham radio transceivers at 80+ feet. 

4. Wide Band: Spans a useable frequency range from 10 MHz to 4.5 GHz. 

5. Dual Mode:
LINEAR - for fully displaying weak signals at the highest sensitivity.
LOG - for displaying input signals ranging over 1000:1 input range. 

6. Sensitivity controller: to manually adjust the input signal level. 

7. Silent Vibrate Mode: Switchable vibrator function that allows detection of signals when direct viewing of the displays is unavailable or undesirable. 

8. Analog Meter and Light Emitting Diode (LED) displays: The LED display is
particularly suitable for viewing from a distance or in dimly lit surroundings - such as nighttime. 

9. Economical: Operating for approximately 80 hours on 2 AA alkaline batteries.
