  • Backlight / Crip display - Very good illumination.

  • Essentially, you can put on the screen virtually whatever you want and wherever you want it, and the screen is high resolution (as is required, to be sure, for detailed maps).

  • The screen is easy enough to read in bright sunlight.
Garmin Edge 800 Cycling GPS Computer-(Certified Refurbished)
  • The display is decent size, but not "iphone" quality.
  • Screen has great viewing in light and dark. Great value for the price!
  • There is not a lot of glare in the sun and it lights enough in the dark to read normally.
  • The maps are very helpful when you are ridding a course. Also the touch screen is very handy.
  • The touch screen is surprisingly easy to use in the cold/wet & bright sunlight.

What customers say about "Features"
Garmin Edge 705 GPS-Enabled Cycling Computer
  • You don't have to have a GPS signal and be moving for this cycling computer to read your speed.
  • The heart rate monitor strap is perfectly comfortable. I haven't felt the need to get the 'comfort' strap instead. I have a 44 inch chest, and have no problem with fit.
  • When I get home from a ride, I upload the data into the Garmin Training Center software, and I can compare every aspect of the ride to previous rides
  • Cadence monitor, speed monitor installed quickly and have worked flawlessly; I have several heart rate chest straps and the HR monitor recognizes all of them.
  • All the components work great and pulling that into their training software is useful.
Garmin Edge 800 Cycling GPS Computer-(Certified Refurbished)
  • It has worked great both inside on a trainer and outdoors. Picks up location very quickly and connected easily to my Wahoo HRM, cadence and speed sensors.
  • The graphic depiction showing changes in elevation was a nice touch as well when reviewing our effort at the end of the day.
  • The edge 800 is exactly what I need - interactive, lots of data to geek out over but that I don't really need, separate bike profiles, and easily programmed gps navigation.
  • The customizable screens are great and it's nice to know its not all in my head when I think it feels way colder than it is (like said).
  • he ability to upload routes is a feature I found very handy this past week as I was able to have the route set to take us directly to our camp sites at the end of each day.

What customers say about "Battery"
Garmin Edge 705 GPS-Enabled Cycling Computer
  • I've have several Garmin devices including: Forerunner 201, 205, 305, eTrex, 60sx but the 705 brings it all together in a small package with a looooooong battery life.
  • After over a year of solid use, I still get 12+ hours continuous (without backlight).
  • It charges now in a few of hours and has good battery life. (Sorry, I have not run it down for endurance.)
  • The battery life is very long (about 15 hours)! I left it on overnight and woke up to it still running.
  • Battery life is good enough for a very long ride - I suspect easily over 10 hours
Garmin Edge 800 Cycling GPS Computer-(Certified Refurbished)
  • I do RAGBRAI every year and this was so great to have! The battery lasts about 12 hrs of running it straight through.
  • The battery life is also great, using it for up to 12 hours per day, with at least 20% battery remaining at the end of each day. Charges quickly too.
  • Had mine for couple years now battery life is amazing over 100 miles 45% etc best computer device on the market :)
  • Battery life even with the backlight permanently on is very good. I lose about 15%-20% charge after a 90min ride with the backlight fully on.
  • The battery seems to be amazing, i've never run out and on a 3% charge i've managed to get it to run for 1hour with the screen on lowest setting, just to track my ride.
