I bought a Suunto T3 with Heart Rate Monitor etc, etc, etc
Following my past experience with Suunto, buying it is the easy part. Reading and understanding the manual requires a PHD.
At just about 42mm, not quite as big as his brother the Vector. Took me a month to figure out the Vector. Had to brush up on Barometric Pressure and Current Sea Level Pressure
Took it out for a spin during an am jog today. It alarms when you've reached max heart rate and also does when below min HR. I'm sure in a month I'll figure out what else it can do.
