Dear Marcel,

Thank you very much for your question. Unfortunately, I can't answer your question because I don't play golf. But it seems that the software used is identical for all Fenix 6x pro models. The differences are in the hardware. Since I don't do ultra runs, I opted for the Fenix 6x pro - so no Solar or Saphire. Hope I could help you.
#Solar: solar panel - longer battery charge (approx. 15%)
#Sapphire: scratch-resistant sapphire glass

Greetings
