Right out of the box, the Garmin Enduro reports overly generous total elevation gain numbers. I prefer my GPS watch to be accurate not generous. Before the Enduro I had been using the Fenix 3 HR for a number of years and its accuracy has been time-tested against so many ultra trail races I’ve ever been in. So I have a solid reference to compare the Enduro with. With that said, I suggest making the following changes:
The Enduro comes with three satellite options: GPS, GLONASS and GALILEO. By default it’s set to use only GPS with options to select GPS + GLONASS or GPS + GALILEO. For Trail Running activity it’s highly recommended to use GPS + GLONASS for increased tracking accuracy. This is a per activity setting.

When enabled, Auto Calibration “consistently results in weirdness like me apparently going below see level by 20 meters or running off small cliffs as auto cal kicks in and adjusts altitude. Leaving auto-cal off you set your known altitude (you can check on various websites (or use DEM only before activity) and then altitude during activity will depend only on baramoter. This approach gives by far the most sensible data for me so far, but if weather (pressure) changes during activity you see slight errors but nothing as bad as Auto-Cal.” (user on Reddit)
■ Long Press MENU button | Settings | Sensor & Accessories | Barometer | Watch Mode | Barometer (Default: Auto). I’ve found Auto jacks up elevation gain a lot and until a future firmware addresses this problem, the only way is to force Watch Mode to Altimeter (more info from Garmin).
Before starting an activity (I do this for Run, Trail Run and Ride) calibrate the Altimeter and Barometer manually by using data obtained from a reliable source: https://is.gd/BarometerPlus. App runs on my Google Pixel 3XL smartphone that uses a precision BOSCH BMP388 absolute barometric sensor ibit.ly/O2MK. An absolute barometer (as opposed to gauge and differential) is necessary for accurate local atmospheric pressure and altitude.
Google is great for many things including ideas to fix problems you hadn’t thought of before. The challenge is usually looking for suggested parts required for the fix which often means (when you know your local hardware stores do not have them) looking online and patiently waiting for them to arrive. I was bothered by the constantly swaying and needed to do something — then I remembered I bought some strong magnets from Daiso and as it turned out, these magnets made the job so much easier. Although the magnets were intended to be a temporary fix, I think they are staying on much longer, and I’m lucky I have fans with metal blades.
Caution: Make sure you use strong magnets or risk injury or damage if one dislodges when fan is running at higher speed. Typically for me, I run mine at speed setting no. 2 which is more than enough cooling.
On the day I picked up my Canon EOS 5D Mark II body some years back, I had a Canon brand screen protector applied for the very same reason when I got my second 5D Mark II body — to protect the screen from scratches and damage like we all do with our prized smartphones. I never liked the idea of adhesive based screen protectors because removing them later would be difficult due to the residue they tend to leave behind. I had assumed these would have been safe because they’re made by Canon but I was wrong. Last week I tried to peel the protector off and to my horror the glossy layer came off leaving behind a hardenedstubborn residue with a matte finish (as you see in the picture right below).
I immediately searched the web for safe solvents I can use that would not attack the plastic screen. The last thing you want is to use a corrosive solvent that attacks the screen leaving it permanently opaque. I found suggestions of WD40 to effectively remove sticker residue but it didn’t help at all. Next, there was mention of Eucalyptus oil (I was running out of household items to try that are intrinsically safe. Thankfully this works …
Apply generous amount of eucalyptus oil to cover the adhesive residue and leave it to soak for a few minutes. The idea here is to soften the layer to prepare for the next step — scrapping the adhesive off using a credit card (I used what was within reach at the time, my Canon CPS membership card).
Be prepared to do a lot of here before you begin to see encouraging results. I applied more eucalyptus oil to keep the screen lubed while I continued scrapping — you can only do so much with a plastic card. I finished the job by buffing the screen with a 3M Microfiber cloth soaked in eucalyptus oil until the entire screen is perfectly clean (I’ve had the same piece of blue cloth for many years and have used it to clean my desktop monitor and laptop LCD — amazing technology.
