$ 149 / Harveynorman. com. au IT IS no surprise a GPS company would release its own fi tness watch, but what is surprising is that the watch ( right) does not have a built- in GPS. The Magellan Echo pairs with your Apple iPhone ( it’s iOS only at this point) and works as an extension of popular fi tness apps, such as Wahoo Fitness, Strava, MapMyRun and Runtastic. The advantage is you can control the apps without reaching for a phone. The disadvantage is it only suits runners who take their smartphones with them. It works with an optional heart- rate monitor and has a battery that lasts six months.
