GPS menu (MRX G Only)
The MRXG Marker locator can be paired to an external GPS device or use its internal GPS module when fitted to detect and store its latitude, longitude and accurate UTC time alongside its locating data or the automatic logging system (MRXG model only).
The presence of GNSS data allows for the data to be mapped easily and to export and save the information directly into GIS systems.

Internal GNSS ‘GPS’
The MRXG Marker locator has an internal GNSS module. When internal GPS is enabled, it will automatically try to “lock” onto a number of satellites as soon as the MRXG Marker unit is turned on.
The time required for the GNSS module to lock onto the GNSS system varies depending on the length of time that has passed since the last time the locator was used, and on the presence of obstacles (like high buildings, trees, etc.) that obstruct sight to the sky.
If the unit has not been used for several days the time to first fix may take up to several minutes.
The MRXG Marker locator display provides a number of icons indicating the presence of an internal and active GNSS and when this has locked to the GNSS system, the quality of the signal received or numbers of satellites received.
The accuracy of the GNSS module is affected by the number of satellites received and best accuracy is only reached when the signal quality is at its maximum.

The LCD GNSS operation icons provide visual information about the status of the internal GPS module:
