Hello, sorry for newbie questions. I am looking to buy a new device and am torn between Fenix 3 and 5 - there are some great deals out on Fenix 3 at present however, the one issue i am stuck with is UltraTrac. I regularly walk 20+ hrs - has the issue with UltraTrac disabling all other sensors been resolved in the 5? i.e. ANT sensors configurable like HRM working. I know this was an issue with the 3 and not sure if resolved in firmware or if the 5 has this issue as well. thanks for any tips!
