GarminEdge 840 GPS Computer(Return to Product Page)

I use this for training, gravel riding and road riding. The touch screen, increased memory and battery life are major improvements and the screen setup is better although that could have been made to be updated via laptop rather than on the device. Unfortunately, there are still some maddening Garmin software quirks such as when device is sync'd to a laptop, it locks up and must be hard reset to to work again. it also maintains a menu system that can only be described as archaic.

It seems Garmin is finally getting better at managing devices as a whole. Settings from previous unit are applied like getting a new phone. The management of maps is much easier, but storage is still too limited. I do like the climb pro for all hills not just when you are on a route. I do not know if I would have bought one just for the sake of it, I liked my 830. But it was a few years old and the new units battery lasts so much longer. I never had issues with the touch screen only on the 830 but it is nice that this one has both touch screen and buttons.

I purchased this as on upgrade to the older 520 model. The 840 works really well and provides a lot of useful data while riding and post ride. Works well with my AXS Power Meter and nice to track both heart rate and power real time while riding. Only negative, this could be I have something set wrong, is that when connected to my Garmin headlight it would run the headlight on full power and drain the headlight battery in two hours. Not a huge issue for me. I disconnected the headlight and now it stays on daylight flash mode and last up to eight hours. Nice upgrade, solid GPS and works well with connected devices except maybe the headlight.
