Lots of info, works well but hard to silence

Very nice display. UI is a bit clunky. Took a few rides to stop it from constantly beeping at me and changing screens. Hopefully once set up, it won't be as distracting (settings are both in device and profile). Battery seems nice and the overall Garmin ecosystem integrates well. Deducting a star for UI and overzealous notifications. Time will tell if it is built well.

RADICAL Improvement over the Edge 830! THANK YOU!
on January 12, 2024
Posted by: DouthatBiker
STAMINA? YES! Seems valuable already!
Navigation? SO much more intuitive, very quick to adapt and lock in on an alternative when I choose a different direction, (sometimes wants to take a route back on track sooner than I will accept, including trails or "roads" that aren't acceptable, but I just ignore that and it adapts again as soon as that option has passed.) Small changes or big ones, both have worked out just great without me being hassled constantly about "Off Course."
GPS is MUCH MORE ACCURATE than the 830. One course on a paved road has ALWAYS with the 830 given SEVERAL "OFF COURSE" warnings even though I'm right on the road. Ridiculous miscalculations anytime I used a course on that road. I did it with the 840 right away after getting it only a couple weeks ago. It never missed a beat or thought I was off at any point.
SCREEN QUALITY VASTLY BETTER with the 840. It's like it healed my OLD EYES! I can actually barely read the small print stuff now, like where it shows what the data field is just above the actual data. I could never see that stuff on my 830, struggled to read lots of things like that. I could see the data itself, like the distance or time or power, but not any of the fine print stuff. Even though the 840 is supposedly the same resolution, it is MUCH EASIER for me to read almost anything even without the reading glasses I would otherwise need.
BATTERY LIFE? Well, suffice to say, it is a big improvement for me so far. I tend to stay well charged up on both my EDGE and my FENIX 6, just because I might choose to do a 4 or 5 or even 7 hour ride the next day on short notice. I always try to be prepared. But the 840 has me letting recharges lag more and more because it stay so high even after a few hours ride. I even increased the backlighting to ALWAYS and raised the Brightness to about 70% because I know the battery will last and the AutoBrightness always seems to dim it just a bit too low for my eyes. (I might have been happier with the 830 in that regard had I dared to force the brightness higher, but I never tried it that high; but even if I had, the battery life would have become an issue at times.)
ALL THE BUTTONS is a HUGE PLUS!!! There have been MANY times on the 830 that I couldn't change the screen because I was wearing thick gloves that were not "touch screen" friendly, or because it was raining and the wet screen wouldn't respond. Now with the Up Down buttons on the side, it is possible even in the worst conditions! The buttons are a little less sensitive than I would like, but I'm learning to press a little higher on the buttons than from side/slightly below and that seems to work much better. Still getting used to what works best.
There is a little downside to having so many buttons because you do have to watch how you hold the device when pressing (OR when NOT TRYING to press them, like when removing it from the bike mount, and the screen isn't locked, you can accidentally press a button, especially the lower corners, without meaning to,) but I'm also learning how to avoid the problem as I use it. KEEP THE BUTTONS ALWAYS, GARMIN! They are a HUGE ADDITION to functionality and usability.
OVERALL FITNESS DEVICE? I am FAR more content with the EDGE 840 becoming my PRIMARY TRAINING DEVICE now. I had to dance back and forth with using the FENIX 6 and the EDGE 830 to dual-record all rides, then check their results, and then delete one or the other recording AFTER making sure the data was okay. The 830 was failing during rides, rebooting, losing data in the process, etc. Not always, but enough that I always had to have a backup device. I still do that, but now, I'm much more confident that the EDGE 840 will have intact, accurate data, AND with the STAMINA factor included, I feel confident that it's the more useful reference over the long haul. The only thing it doesn't record that the FENIX 6 does is the Recovery HR (I would love it if that were possible, GARMIN!) but the STAMINA feature seems like something I want to see every ride and be able to start seeing trends over time, like how low I can drain it and what that leads to in future days.
All in all, this device has RAISED MY OPINION OF GARMIN a HUGE AMOUNT! It still needs to be dependable over time, and I did have about 2 or 3 unexpected things in the first couple days, a freeze-up of the device after a Garmin Express update, and a couple reboots that came from nowhere BUT these did not happen during rides, and cleared up just fine. I hope they were just "growing (birthing?) pains" of a brand new device. :-)
I've recorded 13 rides with the device so far, and all have been flawless as far as I could see. And USING the device on rides is BETTER THAN EVER BEFORE. I'm like, WOW! HAPPY HAPPY HAPPY!

Why did I wait
on January 12, 2024

Having the 840 attached to handlebars is a game changer. The stats of my ride are quickly viewable. The map is spot on. The ease of use is exactly as advertised. Another bonus is it can be taken on & off and then placed on another bike. One thing I need to complete the package is a heart monitor. Which I just purchased.

Love this little wonder
on January 8, 2024
Posted by: Clara12
I bought this concerned about being able to read on the road. I can report I have no issues. You can adjust the font size and also controlling the amount of data per screen also affects font size. Has more features than I will use. Very intuitive to navigate once you understand the buttons and have a chance to play with.

Literally trust my life to this device
on January 7, 2024
Posted by: Becca B
from Seattle, WA, US
I use my garmin for training six days a week and navigating through remote trails and have been incredibly satisfied with its navigation features. I trusted it to lead me through the bootleg burn area in a remote part of the Cascades where no trail or blazes were left after the fire, and ended up navigating for both me and friend whose gps device was less reliable. Not an exaggeration to say I have trusted this device with my life! The 840 version fixes some minor qualms I had with the 830, which I used for tens of thousands of miles. I find the 840 connects to my other garmin devices more reliably and uploads rides to my phone consistently as soon as I stop a ride, something I had problems with on the 830. I use it as the hub for all my rides and love how seamlessly it works with my rally power meter and garmin in reach. The 840 has a better resolution, and now I can see photos people text me while I ride! only downside is that encouraged garmin to cram a lot of info on the screen, making the user interface a little challenging with gloves/ in the rain/ etc but I think I will get used to it.

Great but a couple of things to improve.
on December 29, 2023
Posted by: CoastsideCyclist
Upgraded from a 10 year old 810 due to battery issues. Much smaller and lighter. Like the new features when paired with a phone. Couple of things would make it better: 1) the ability to choose your own name for the data screens. Seems like a no brainer to me. Having to open each one to see details when reordering is a pain and unnecessary. 2) when you go to pair a sensor, you see ALL sensors paired not just ones paired to a specific profile. I have 3 bikes so would like to only pair certain sensors to each profile. At least you can rename the sensors so it is not as confusing.
