does this come with the coded transmitter and how do you upload to a computer/ where do you buy the extra to upload?
The coded T31 transmitter is included, as stated in the specs above.The way the watch and computer talk is called Uplink. It is software that utilizes the computer's sound card and speakers to facilitate communication. Generally the speakers that are found on laptops do not work.I used it with success on an older Polar watch with separate desktop speakers.
