Hmm some folks like Vortex bios. .spotting scopes..others Swarovski HD...
I have a 10 year old Petzel. ..so it works and has passed the durability test..
However...
I bought a Fenix headlamp last year..light years ..ha ha ha..ahead of petzel..in materials..light output..design..it's in that Swarovski category..yap that good..and i too bought from Fenix Frank.
Cheers
