Review on Radiation Detector Counter Dosimeter Ecotest by Chuck Hernandez

This geiger counter has an impressive response time. Most other counters take a full minute to get a result, while Terra-p gives an initial result in 10 seconds and then gets more accurate over the next minute. This will let you know faster than most that you are in a dangerous environment. It also has a battery saver feature that turns off the faucet and display but continues to count your dose and wakes up with an alarm when the threshold is reached. Really great technology that everyone can use, from hobbyists to professionals.
