A feature-packed, small and impressive update on the popular Edge 810

The Garmin Edge 820 is a features-packed, compact and neat cycle computer that is a decent update to the popular 810. Perhaps the screen could be a little more responsive and the GroupTrack could be more accessible, but overall it's an impressive piece of kit.

You can read my first thoughts about the latest bike computer in Garmin's 800 series here, with the 820 taking the place of the 810 in the lineup, but I have now had a little more time with the unit and so here is a more thorough rundown.

Size, looks & installation

The Edge 820 is 49 x 73 x 21mm – the same size as the 520, which means a smaller screen, something that I was initially sceptical about in terms of being able to effectively use it for navigation. However, this concern was unfounded and it was easily good enough to direct me without needing to go all Froome and stare at the computer from just millimetres away. Certainly, it's not at the same level as the 1000 in terms of navigation purely because of the screen size, but it is more than enough for my needs.

In terms of installing it on the bike, the unit uses the same Garmin mounts as previous units and comes with a couple of stem mounts and one out-front. Fitting them to the bike is easy, with either rubber bands or a quick few turns of an Allen key. One thing that I have always liked about this is that it makes it easy to transfer the computer between bikes when needed without needing to cut cable ties like with other mounts; you can just undo the rubber bands and then redo them on the other bike.

It is aimed at the performance cyclist who also wants to be able to navigate, so isn't as bulky as the 1000, but packs in more features than the 520. In terms of looks, it is almost indistinguishable from the 520 apart from the lack of buttons on the side of the unit. It is a sleek looking and small unit that sits nicely either out front or on the stem without taking up too much bar real estate.

Navigation, operation & screens

Navigation has been improved with some of the key features from the more expensive and navigation orientated 1000 moving down to the 820, such as round trip routing, allowing the computer to create the route for you. It's a nice touch that worked well for me when I was testing it out in an unfamiliar area and gave me a few route options based on climbing and intensity. It also doesn't require external cards to be inserted for new areas of the world – instead Garmin has included all maps on the unit from the start. To be honest, I didn't use it outside of the UK, but all maps I used were up to date and worked well.

Maps have also been improved with a clearer layout, closer to the kind of thing you would see on a regular sat nav. It makes it easy to see exactly where you are going and there is less incentive to change to a custom mapping layout, which I have done on a couple of older versions.

The screen may not be as big as on the 1000, but turn-by-turn prompts were still simple to follow and despite its small size it was good enough to clearly show me where I was heading, even when I was off course. I found that adding in a postcode, town or specific site was effective and worked well, getting me to the correct place without fuss. That said, I did have a couple of frustrating times with the computer rerouting some pre-planned routes I had; for example, when halfway between London and Brighton I found myself needing to ride two miles on what seemed like an abandoned footpath...

As with other Garmin units you can customise the data you see on each page and then set activity profiles, which means you can switch between different screens for different uses. For instance on my training screen I had seven data fields including time of day, while on my race activity profile I had four data fields, so they were larger and easier to see at a glance. There is also the ghost cyclist screen where you can 'race' against another rider who rides at a constant speed, something that's been included in most Garmins for a while and which I regularly use for training.

Garmin has also added GroupTrack, which allows you to track up to 50 riders within 10 miles of you. Essentially, if you get dropped or lost, you can easily see where others are. This has many uses, but requires others to have compatible Garmin computers and to follow you on Garmin Connect. I managed to test it a couple of times with others in my club and it works well and I could clearly see where people were on the map. You can also see if your friends are out on the road near you, which is a nice touch. However, there are still relatively few people who use the platform compared to something like Strava, but this may change as GroupTrack grows in popularity.

The unit is operated predominantly through touchscreen, but with two buttons at the bottom and the on/off button on the top left. The buttons on the bottom are start/stop and lap, although they also operate as multi-functional on certain screens. The touchscreen works okay, but compared with button-controlled computers and the 1000 it seems a little sluggish, sometimes taking a second to react. However, it worked just as well with touchscreen-enabled gloves and was still usable in the wet, so good in a variety of conditions.

Data recording, uploading & connectivity

The unit comes with a decent amount of connectivity, with ANT+ and Bluetooth meaning it is simple to connect sensors on the bike and smartphones. I used it alongside Garmin's more modern accelerometer based sensors and also the traditional speed/cadence sensors, with both connecting easily and picking them up within a few seconds of starting rides. It also shows notifications and information from your smartphone, with a separate connection for notifications and uploading. This means that you can have one without the other, which saves battery life on both the phone and unit. GPS is also noticeably faster to connect than on the 810 thanks to the inclusion of GPS and GLONASS, meaning more satellites can be used and identified.

It is also usable with Varia devices, including lights and radar. I didn't test it with these features but I was shown them in action by Garmin and they seem to work well with the unit.

Garmin is also catching up with other bike computers in delivering 'incident detection', which essentially means that a text message and location is sent out to a pre-determined contact number. I tested this once and it seemed to work well, with a text being sent after mimicking a crash, although I would say it would be best to turn it off if it's going to be used off-road as it can be a little sensitive.

Recording was as good as anything I have seen from other GPS computers. There was a little loss when I was riding under cover (trees and tunnels for instance), and among tall buildings it tracks better than the 810 did, but once in a while you can see a bit of an erratic twitch in your recorded route.

In terms of data on screen, it seems accurate and using it alongside two other computers and a phone, it was quick to note changes in speed and cadence, with gradient also quickly shown. It is actually one of the best gradient recordings I have used, picking up changes when going over short bumps and quickly picking up slight changes on longer climbs.

Uploading from the unit is done through Bluetooth to your smartphone, which is quick and easy through the Garmin Connect app. From there you can either download the file to your desktop or share it with other sites. For instance, it would take roughly a minute from uploading a ride for it to appear on Strava.

Battery life, weight and price

Battery life is claimed to be around 15 hours, which seems about right, but there are also battery saver modes which can help to extend this if you are out on the road and have forgotten to charge the unit. This essentially just turns off the display but keeps recording. There were a couple of times when battery life inexplicably declined and there was little warning of levels, so once or twice it would just turn off mid-ride, which was a little frustrating. Garmin says there is shortly going to be an update to fix this issue.

The unit comes in at a respectable 64g, which is actually less than Garmin's claimed 67.7g. It is about 6g more than the 520, which, bearing in mind it has significantly more features, is impressive. It isn't the lightest computer you will find, but you are unlikely to feel like it's weighing you down on a climb and is nearly half the weight of the 810.

Garmin is offering the 820 with an RRP of £329.99 as a standalone unit, or £60 more with a heart rate monitor thrown in. It is also available in an Explore model, for £279.99, which offers fewer performance measurements, so is predominantly a navigation device. This price seems about right for a full colour, touchscreen device with the kind of capabilities it has.

Conclusions

I have been impressed with the Edge 820. It has as accurate tracking as I have found on a GPS computer, the connectivity is strong and it is simple to use. Perhaps the screen could be a little more responsive, the battery life could be a little better and the GroupTrack could be more accessible (this may change as more people begin to use it), but with the frequent updates we are likely to see from Garmin, these issues are likely to be resolved. All in, it is probably the best performance and navigation computer I have used and that Garmin has been able to pack it all into such a small unit is astounding.

Verdict

A feature-packed, small and impressive update on the popular Edge 810
