The problem is that skin based HR requires a really tight connection to work really well. The Polar OH1+ on a bicep gets a much better connection than anything (Polar OH1+ or a Garmin 945, anything) can make at the wrist as the bicep is
like rocksquishy. The bones in the wrist make it hard to keep a sensor pressed against the skin tightly.
