Comparison Garmin GPSMAP 67 vs Garmin GPSMAP 66SR

Galileo is a European satellite navigation system designed as an alternative to American GPS. Note that it is under the control of civilian departments, not the military. With a full fleet of 24 active satellites, the system gives an accuracy of up to 1 m in public mode and up to 20 cm with the GHA service. Working in conjunction with GPS, the Galileo system provides a more accurate position measurement, especially in densely populated areas.

The operating time of the navigator on one battery charge or a set of batteries depends on the power source (see above).

This parameter is more visual and closer to reality than technical information about the type of batteries, battery capacity, etc. However note that the operating time is usually indicated for a conditional perfect situation: a good signal level without the need to reconnect, low screen brightness ( or completely turned off the backlight), minimal use of wireless modules (Wi-Fi, Bluetooth), etc. Practical conditions inevitably differ from perfect — accordingly, the operating time may differ noticeably from the claimed one (usually in the direction of reduction, but sometimes vice versa) . Nevertheless, the operating time stated in the characteristics is quite reliable information, and it is quite possible to evaluate the capabilities of the selected device, as well as compare it with other models.
