Smartphones have revolutionised the way we navigate and use GPS systems. Their map functions are perfect for everyday use and navigation, however when you’re out in the wild, you may want to consider something that uses a slightly higher-level of satellite navigation, ensuring you are able to keep track of your movements and crucially notify others if you happen to need assistance. We’ve come a long way from maps and compasses, and even handheld GPS devices themselves now make use of new, updated technology to ensure maximum practicality when in remote areas. Battery life is another key factor and this is an area in which we’ve seen huge progress in recent years. Size and portability are of course an issue, and think about the kind of maps that’ll be most useful – we like to have the option of OS maps, for instance, on our handheld GPS devices which not all providers accommodate. We like also to look at weatherproof ability – and ensure the device we’re investing is IP rated and waterproof. Out hiking?
