Previously same class using icardio and polar regularly my figures have been Max 169 and average 149 these figures have been consistent pretty much.
I notice Ant+ refresh doesn't seem real time whereas the Polar is constantly changing figures.
I wonder if its a ant+issue or if anyone else has the same lags with ant+.
I had a zepyr hxm that behaved the same as the Polar so think the Garmin is a bit off...
The Polar has t13 support and behaves the same with gym equipment
