Hi All Just a quick thread from me. Been using the Frontiers for a couple of years now and found them excellent, But desided to upgrade them and went for the Sapphires thinking they would be even better unfortunately did not find them so and I don't no why they both seem the same but I find the Frontiers have a more easy view. So gone back to them. on a nother note checked out the Zeiss conquest 8x42 at minsmere to me the the view and brightness were the same and the frontier has a wider field
