Yes, the Sigma belt is picked up by the $25 PM3 Heart Receiver, and at the same time by the Sigma watch so I can get it's current % of max HR, Workout avg and max HR plus % in 3 zones. I think almost every non-ANT HR belt broadcasts using the Polar signal, my Suunto T3 does.Tall Man wrote:Carl,
Are you saying the Sigma monitor works via the "Polar" pickup with a PM3 (or in my case a PM2)?
The thing I like about the PM getting the HR is its graphed by RowIt and RowPro; otherwise, the watch stats are more interesting.
I'll have to check to see if the Garmin ANT belt also sends a Polar signal.
Re buying PM3 or PM4 I just saw this "If I were buying a new rower I'd go for a model D with a PM4. The PM3 isn't being enhanced. C2 have stated that there'll be no new features on a PM3." which I agree the PM4 has a better future.... but PM3 will work just fine... and they did enhance PM3 with "Undefined Rest" but you have to have a newer one that probably has a newer processor.
