With the sports watches HAC4(Pro), HAC5, CM414M and CM8.x you have the possibility to record your sports activities up to 64 hours.
If you want to extract the data from your HAC4, then you will need the HACtronic interface and software.
The HAC4 is invaluable to those wishing to record and analyse their training and competition performances or who participate in adventure holidays as 64 hours of data can be stored and recalled later using the PC Interface and software (HACTRONIC).
