The best outdoor GPS must have good reception and be adaptable to any kind of environment.
The perfect outdoor GPS has atleast 6-12 channels, to enable precision and an external antenna to enhance signal reception around skyscrapers and tree cover. Also critical is water resistance and the best outdoor GPS units feature an IPX7 waterproofing standard which can brook dousing up to a depth of one meter for half an hour.
GPS models built with transflective screen displays are readable in all light conditions and are ideal for all outdoor activities. A transflective display accommodates both backlit and reflective display technologies, by switching between these two modes depending on the environment, which results in great readability regardless of the lighting.
The best outdoor GPS also come with an external memory/storage card for extended map storage.
