Son #1 is prepping for an 18X contract. I enrolled in in a 2-day Land Nav course and wanted him to use what he'd be using in the Army. I was concerned about purchasing this item via Amazon as some reviews indicated they received a defective or used compass. We've been regular viewers of the FNG series and when the store opened I knew where I needed to go. The purchase process was seemless and the item arrived in record time. His course is scheduled for the end of the month so I'll get his impressions later. Suffice to say I'm extremely happy with the purchase. Cheers!
