Automatic & Manual Environment Adaption

After powered on, the device will auto run an environment adaption to get better results due to each location's unique situation. This helps detect actual GPS bugs, and less false-positives or failed detection. The sensitivity will adjust and adapt on its own so both novice and advanced users can spend more time locating bugs and less time fiddling with unnecessary controls.

For best case scenarios its suggested to disable items that could be within the Active Range of the GPS detector such as strong Radio Frequency Signals, Examples as base station, TV station, construction machine or welding processing where emits high electronic waves. Power OFF all known Active Wireless Signals – TV, Mobile Phone, WiFi Router, Bluetooth etc etc..

Standby / Idle Cellular Registration Detection

All active GPS trackers use cellular signal to transmit the coordinates of the GPS tracker's location. As the signal strength of a cellular signal weakens, the cell phone will re-scan the cell site to do a new registration automatically.Or the cell site will initiate registration on its own by sending a signal to the cell phone, causing the phone to transmit and identify itself. This will detect these standby and idle phone signals when it does the registration with the cell site. It's important to note that each interval time and number of times of registration is different between each network and cell phone.

Does exactly what it says it does, finds all transmitting devices that use cellular signals from active GPS tracking devices which in my line of work I come across fairly often. I highly recommend this to other PI's out there. Nothing complicated.
