Garmin Edge 705

Nov 21, 2009

If you are a tech head like myself you will quickly overlook the Garmin Edge 705′s price tag and look at is the ultimate training tool. The Garmin Edge 705 does it all, and I really mean all. It is the ultimate bike computer and training partner and is used expensively by the Garmin-Slipstream pro-cycling team.

The Garmin Edge 705 is available in a number of different packages. The packaged reviewed here includes the heart rate sensor and cadence sensor. In my opinion if you’re buying the 705 as the ultimate tool, go for the package that opens up its full potential. The only thing that need to be sorted out with the purchase is what maps to get, the 705 does not come packed with maps.

At first glance the 705 looks huge, only because we’ve been used to the tiny traditional bike computers that display a couple of lines of information. Once installed onto your bikes stem or handlebars and fire it up, you will realise for the first time that you have been missing out in the past.

The 705 is waterproof with solid rubberised buttons on either side of the unit and a joystick and button combination on the front underneath a large colour screen. The rear of the unit has the integrated mounting bracket and the mini USB charging/data connection port.

Setting up the 705 is a cinch. The amount of information you wish to display on a ride is fully customisable, and you have two full screen of user information to customise. On the first screen I displayed eight functions: elapsed time, speed, distance, cadence, heart rate, time of day and calories burned. On the second screen, I have opted for a more basic display showing: speed, time elapsed, time of day and distance – similar data shown by a traditional computer, but on a much large, easy to read display.

The menu button on the lower left side reveals all the settings, navigation entry and stores data. You can easily access saved ride history and pre-determined training ride courses that can monitor your current progress vs a previous – you become your own training partner.

The mode button on the lower left side changes screens by alternating: map, elevation, and the user customised data display. The map and elevation screens can be zoomed in and out with the zoom buttons on the upper right side. The map screen can be customised with user required information. I have displayed: speed and elapsed time so I don’t have to toggle between map and information screens when I just need the map display. Customising the map screen does make the viewable map area smaller, so you would want minimal user information displayed.

Multiple profiles are available for users and bikes. I have a mounting bracket installed on my road and mountain bike and easily switch between the two by selecting the appropriate profile. Nothing else needs to be connected. For the road bike, the cadence sensor monitor cadence and speed. On the mountain bike, I figure that cadence if not required and leave the speed to be monitored by the GPS.

Upon turning on the device it searches for satellites like all GPS devices do. After a few seconds it finds your location and you are ready to roll by pressing the start button. The 705 accurately tracks you route in real-time pausing the elapsed time when you come to a stop. Upon reaching your destination end the ride by pressing the stop button. Before beginning a new ride you have to remember to reset the display. After downloading your information to a computer the unit is automatically reset for the next ride.

The heart rate sensor wraps around the chest in the same way other HRM transmitters do and accurately records your heart rate. Advanced HRM functionality such as training zones can be applied if required. I do question the 705′s accuracy when converting HRM information to calories burned. Compared with other HRMs the Garmin seemed to be rather high.

Battery life is stated as approximately 12 hours which I have never found not enough. I can only see that you will need to supply a charging solution if riding very long rides such as endures or similar. The rear mounted USB port provides standard charging from a wall mounted power source or from a computer. The same USB port downloads data to your computer.

There are a range of software applications for your computer including the downloadable Garmin Training Center and Garmin’s web-based Garmin Connect.

In summary, the Garmin Edge 705 is a very special device. It displays everything you need, provides accurate guidance and records all your data for analysis – it really does it all.

Get the Garmin Edge 705 – you will never look back.
