A Garmin Etrex adapter cable is highly useful, as this cable allows you to power your device without batteries. This is important, as there are some situations where your batteries may not function like they should.
Particularly, in the situation where your GPS unit is mounted to a motorcycle or ATV. As the engine vibrations can cause battery failure issues, making use of the adapter cable and other Garmin GPS accessories can help prevent damage to your unit.
The Garmin Etrex adapter cable, when used with Garmin GPS mounts, allow you to use your unit where ever you go. This is very important, as your device needs to be functioning when you are on long trips. If the device does not function when you are lost or traveling, you will not be able to access features such as travel directions and location positioning.
To be able to fully appreciate how important this is, you need to know how the GPS system works. The transmitter, or the device attached to your motorcycle or ATV, communicates with satellites that are in orbit. These satellites then relay information back to the unit, which translates into your current position. Other people can locate you, in case of an accident or you have become lost, by simply tracing your GPS unit to its current location.
This is highly useful if your motorcycle or ATV breaks down while you are exploring or traveling. If you are uncertain of how to install or use your adapter cable,try contacting an on line dealer for more information.
