Bryton GPS very inaccurate

[The Don]

I purchased a Bryton Rider 50 in December. I have noticed that it records the amount of climbing incorrectly. When compared to a Garmin and Polar on one particular ride, the Polar & Garmin were 950m & 970m respectively and the Bryton was 3500m. I have also noticed that it displays incline incorrectly. It can go from +22deg to -35deg while riding on a flat road. Tonight I discover that I have lost a weeks worth of training on the web site.

 

I think it is time to go back to Garmin which is tried and tested and is at least accurate. So be warned.

yikes. those are gross inaccuracies. What does Bryton support have to say about it? might be as simple as firmware update to your unit?

[Agteros]

Single occurance error, or once off?

Polar use barometric pressure for ascent (more accurate)

Some Garmins use GPS (less accurate), others use barometric pressure

What does your Bryton use?

 

Maybe there is a problem with yours, and it can be replaced under warranty?

Also lost all my data ... The guys will not admit they stuffed up. All very quit for support

i have been using my rider35 for about a month and half now and logged at least 3 rides per week and everything has been 100% accurate (in comparison to previous logs using my phone). That includes going through some heavily wooded areas too.

how did it loose all your data? When i download my data - after it downloads it to my collection it removes that trip off the device if i say yes. Di you loose all your historic data that is sitting online?

Lost the online data .. Had deleted from unit as it was downloaded ... I see Bryton sent out notice this dd happen some users. Very odd

I bought my wife the Bryton 35 and neither the cadence nor the heart rate monitor have ever worked. Bryton was also, to say the least, not exactly helpful

Check if you can't reset or recalibrate the unit. Some of these types of products have to be calibrated at sea level to function correctly. Contact local import agent in SA or google altitude calibration.

No not sea level..... that means you will have to drive from Joburg to St Lucia (the closest sea!!!!) You should be able to calibrate it to any known level obtained from a 1:50,000 topographic mapset or other data.

Tks for the heads up. I was gong to replace my Polar 725 with one!

Even Garmin can sometimes do funny stuff, just moved my cadence sensor to my new bike this morning, so wanting to check if it picked up cadence i sit on the floor swining the pedals. On the same screen i have my %Gradient and my Avg Cadence so i see it starts climbing all the way up to a 486% gradient. So no explenation for that. That said on recording a ride, i generally almost always get the same results with my garmin.

Isnt the Bryton a copy of the Garmin. Maybe that is why both act strange?

Well its better than my three phones that add up to additional 3km per ride. and never give me the same elevation correctly twice

 

garmin is at least +- 10m differences and +-100m differences at the end of a ride. And no the bryton uses a totatlly different frimware package and sattelite set.
