While Garmin Oregon 650 GPS Receiver retains most of its features from Oregon 600, one major difference between the two is the addition of Garmin’s rechargeable batteries and a built-in camera in Oregon 650. The camera can also work as a flashlight or SOS beacon. The Garmin batteries are standard AA size which are connected via a USB cable and can be charged through a computer or mains with an A/C plug adapter that comes in the box with Oregon 650 only. Oregon 600 also uses Garmin rechargeable batteries but the extra and high cost of these batteries encourages customers to purchase Oregon 650 instead which delivers more value at its price. Users are able to ‘geo-tag’ the photos, taken from their Oregon 650, which also function as waypoints. This attractive feature enables Oregon 650 users to operate the device’s waterproof camera as a GPS unit, a function which is absent in Oregon 600. There is also a vast difference between the two devices’ built-in memory capacity. While Garmin Oregon 600 GPS Receiver only offers a nominal 1.7GB, Oregon 650, in view of comparison, has 4GB built-in memory. However, both devices offer a slot for a microSD card, in case the built-in memory capacity does not fulfill the user’s needs. Apart from these features, Oregon 650 presents buyers with the option of purchasing Oregon 650 Garmin GB Discoverer 1:50K Bundle, which comes with a microSD card providing coverage of GB Discoverer 1:50k full Great Britain. In view of the extra features, the $78 price difference between Oregon 650 and Oregon 600 is nominal. The waterproof, integrated camera doubling as a flashlight or SOS beacon along with the rechargeable batteries, more built-in memory and the option of GB Discoverer 1:50k bundle, are reasons enough to lean more towards the Oregon 650 model by Garmin.
