Im new to Garmin GPS units and reading the history on them the new 520 Puls seemed to be a good place to jump in. Pretty decent tech for the rapidly falling price. The data and screen are great, more than I know what to do with. The Garmin Connect App is pretty basic, seems you need Strava and other third party apps to get more value out of the GPS data. Uploading routes is still clunky having to plug your device into a laptop but its pretty solid once you get it in the device. All and all its a cool toy, we arent totally there yet with GPS cycling computers but its cheaper than ever to try it out.
Coming from a 4 year old Edge, this is easy to read. It finds the satellites quickly, and you can program on the display what you want to see. Trailforks is not as easy to read as on a phone, but if you don't want to ride with your phone on your bars off road, this will save you from pulling it out at every stop.
This device opened up a while new world for me, the information generated together with my Garmin Vector 3 has made me more aware of my baseline and identified areas where I can improve thus making my cycling experience more enjoyable
I got this unit as a replacement for an Edge 820. The 820 had an almost unusable touch screen and I always wondered why they didnt have a 520 with mapping. Overall , the usability of the unit is great. The buttons positively move from one screen to the next in a deterministic way unlike fumbling with the touch screen. The mapping function is pretty good , I am able to upload routes from my iPhone or computer and it works pretty well. The only thing I wish it had was to navigate to a map point without actually physically being at the point and saving it. There is a work around which involves creating a route on a smartphone and uploading it to the unit. But you need a smartphone to do this.
i love using the new Garmin 520, it has everything the 520 has Plus the slightly toned down maps of the 820. overall i like the new maps it comes with. wish the screen was slightly bigger but it fine overall. Also has a slightly updated data fields which look great.
