Everything is in the title of the comment. Garmin thank you for this excellent show. No thank you Amazon for the description of the product as a "GPS Watch Heart" which does not record the heart beats fault cardio strap (option + 50 euros) it's a little lighter.
Go hop on hop returns to checkout!
Following call to Amazon customer service, I look forward to in the coming days, changing the material to indicate to potential future customers as cardiopulmonary strap is not supplied and must take optional!
