Waterproof

Indicates the extent to which the GPS device is resistant to water and weather conditions. This is important because the device is exposed to rain and water spray while riding.
The “X” in IPX indicates that no specific rating for dust protection is provided (the first value in the IP code normally refers to dust protection).

• IPX5: Resistant to light rain and water spray.
• IPX6: Resistant to heavy rain and powerful water jets.
• IPX7: Fully waterproof and resistant to temporary immersion (up to 1 meter for 30 minutes).
