SPECIALIST SAT NAVS

Many of us rely on our smartphones for day-to-day satellite navigation, but if you are towing a caravan, direct routes that can be taken by cars are not always suitable.

Narrow, single lanes can see your bodywork scratched, and the stress of some tricky reversing if there is oncoming traffic. There are weight limits on bridges to think about, as well as headroom if you are going under that bridge. Can you navigate those sharp bends and steep hills? And where will you be able to park or stop overnight?

You need a sat nav that allows you to key in your outfit’s vital statistics and find a route that avoids such hazards. Our round-up of specialist sat navs can do that and more, offering a range of extras including Bluetooth, compatibility with reversing cameras, traffic alerts and campsite locations.
