Outdoor GPS firm Magellan has announced its first sports fitness watch for a fourth-quarter release. The Magellan Echo is described as a smart running watch and links up to a smartphone via Bluetooth and can then be used with over 100 fitness applications, including RunKeeper, Runtastic, Strava and MapMyRun.The Echo can be used as a general wristwatch, with a read-out displaying time, day and date, but any fitness data from the compatible apps can also be shown on screen thanks to its Bluetooth Smart connectivity. Running stats, including elapsed time, distance and other fitness metrics, can be accessed through the watch in real time, and it can also display notifications and achievements.Some smartphone functions can also be controlled via the watch, including lap starting and stopping on a fitness application, and next song, play and pause for music playback.It has a removable battery so on the positive side doesn't need recharging. But it will need to be replaced when it runs out somewhere down the line. The design is ruggedised and the watch is waterproof to withstand adverse conditions.Magellan has chosen the Wahoo API for app integration, so any app on that platform will work.The Magellan Echo will be out in the US in Q4 2013 and will cost $149.99 (\u00a398) or $199.99 with a Bluetooth Smart Heart Rate Monitor. It will be available in black, cool blue and warm red.UK availability will be roughly the same time, but pricing is yet to be announced.
