Is there a big difference between the 5 and 5x plus?
This. I stopped using a GPS when I bought my Fexix 3 Sapphire. Love mine.Have had a 3 saphire for a couple years, really like it. Lot of useful features, maps, saving points and routes. Sure you know there's much cheaper ones out there for just tracking runs but the extra for the fenix was worth it in my case. If they offer the 5 in saphire and you're as had on watches as I am then get it. Seems indestructible.
