The Garmin Montana 650 is a premium handheld GPS system which is very versatile and adaptable for a variety of different uses outdoors, in the car and on a fishing/sailing trip.

At the centre of the Montana 650 is a large sunlight-readable 4-inch colour touchscreen display which features a QWERTY keyboard for taking notes and finding things quickly. The display is also dual-orientation and can be viewed in either portrait or landscape mode - useful when using the device in varying environments such as at the helm of boat, behind the wheel of a car and a walk in the countryside.

The 650 handheld unit locates satellites quickly and maintains satellite tracking even when in built-up areas or in woods, for example. The screen also changes to “night mode” automatically when it starts to get dark for continuous viewing throughout the day and is also waterproof to IPX7 standards.

The 650 is part of the Garmin Montana range and includes the following premium features:

‣Built-in 5 megapixel digital camera - the '5' in 650
‣Electronic compass and barometric altimeter
‣Internal 3.0GB memory

With its built-in 5 megapixel digital camera, the Montana 650 enables you to take photos and automatically geotags them with the GPS co-ordinates of where they were taken. This enables you to view and navigate back to exact the location too.

The Montana 650 also features a built-in 3-axis tilt-compensated electronic compass, a barometric altimeter and wireless connectivity with other compatible Garmin handheld devices. Enabling you to wirelessly share geocaches waypoints, tracks and routes with other device owners.

This is a sophisticated electronic device. It is important to read, understand, and follow the instructions provided in the user manual (usually available via the 'manual' link above). To ensure optimal performance, you will need internet access and should regularly download and install firmware and software updates as recommended by the manufacturer.

Under the Consumer Contract Regulations, you have 14 days from receipt of purchase to verify compatibility with your internet-connected device.
