It's worth persevering with the Kiub. I admit I was missing shots I shouldn't have until I wrote a practice mission to check rangefinding with the stadimeter - it was out, but I suspect that's down to my laptop display driver. Once I worked out the error and how much correction to apply, I started getting good results. Where the Karamazov KiUB really scores is making the stadimeter a reference tool. You're not limited to a preset reference point. Can't see the mast at night? - Just use the stack as your reference and estimate the height difference from the mast in the recog manual. 25% more work for 100% more control - also, satisfying as it is to get the "Torpedo Impact" report - it's twice as satisfying to get it when you make a tricky shot, all by yourself. You don't even mind duds so much, because it means you got them on target.....
