Some questions to ask when buying a GPS
- Does the brand have a good reputation?
- Does it have a backlit screen which is easy to read and contains all the information required without having to scroll through several screens?
- Can it switch between portrait and landscape (vertical and horizontal) display on the screen?
- Is it simple to operate (even with gloves on)?
- Is the unit water and dust proof?
- What temperature range can it operate within?
- Does it have a battery indicator which accurately indicates the charge remaining in the batteries?
- How long do batteries last under normal usage?
- Will the unit accept disposable batteries as well as rechargeable ones?
- Is there a simple ‘on’ button or a ‘switch on’ sequence which avoids accidental start ups while in the pack?
- Does it switch off or shutdown automatically?
- Will the weight of the GPS be the ‘straw that breaks the camel’s back’?
- Is the model designed to work well under tree cover?
- Will the screen indicate if I have 2D or 3D resolution?
- Will the unit allow manual addition of variables such as altitude?
- Is there a visual representation of the number of satellites in use?
- Does it have a lithium backup battery so any stored data is not lost when changing batteries?
