Suunto Smart Heart Rate Belt - Aktivitetssporer med brystbelte - svart - båndbredde: M - Bluetooth - svart

I am using this in combination with the Ambit 3 peak for a mix of running and some indoor cross training on a standing bike. I am using electrode gel to ensure good contact. The sensor is superb - much more responsive than a wrist based hrm with only a couple of instances so far when the rate has (temporarily) drifted off. It is also comfortable to wear. Finally, when running with it, you get a running fitness score at the end of each move, which is essentially an estimated vo2 max assuming elite running efficiency. Very good - allows you to track progress even if your programme is based around a high volume of lower intensity distance training. Highly recommended overall.
