Both northern and southern hemisphere models can be used over a wider area of the globe thanks to an upgraded magnet. You can also add a re-tractor to the wrist version so you can attach it hands free on your BCD. This compass can be tilted far past any other compass before it starts to stick !! Twice as far as the next best compass !!!
