Familiarity: I've used it several times
As a Suunto Pro team member that spends a lot of hours in the mountains, it's important for me to have a tool that can last a long time. The improved battery life in this Suunto 9 puts it in a class of its own. The various battery life modes from 25-120 hours, help auto adjust certain settings that effect the battery life, making it really easy to get the best performance out of your watch for the time that you need. I also like to train by heart rate when accumulating a lot of vertical gain to monitor my efforts appropriately. I used to have to be very strategic when I would use my Spartan Sport HR Baro or my Spartan Ultra. Now in the Suunto 9, I have an accurate wrist based HR watch with unparalleled battery life that keeps me training smart in the mountains for a long time!
