Are the Tomtom proprietary hr sensors just as good as the Mio versions

I recently picked up a Runner cardio on ebay with the Mio hr sensor and very impressed with accuracy and the watch in general. I use it for cycling even though it doesn't have a cycle specific function but the GPS data is the same anyway. If I chose to get the Spark 3 is there any difference between Tomtom's own sensor and the Mio. I've noticed a lot of refurbs on Ebay.

The sensors in the later models were comparable to each other but are far worse than what is available in other brands today. You would likely be making a mistake buying a Spark 3 in any case, even used at a discount. TT Sports went out of business over two years ago and there has been no new development or fixes for known issues and support is severely curtailed. Rather than buying 4 year old technology, save your money and put it towards a newer better watch with better sensors..

Can't answer your question, sorry. But wouldn't it be much more effective to compare the Runner Cardio with anything known as 'quite accurate' instead? A comparison of two devices (with higher +/- tolerances than any medical use device) couldn't tell the truth!

As far as I know it's just the current model Apple watch so far meeting medical requirements to a certain extent at least.
