If anyone is in need of a pair of superb powerful binoculars for observing a nest site for bird protection ie peregrines etc we have taken in a pair of Vortex 18x56 .mint basically used once . They are about £1800 new these are on offer with 12 months guarantee for £960 . Be aware they are not really hand holdable or for use for normal birding, but for anyone willing to use them like a scope on a decent tripod to observe one area they would be great. Pm me if you want details of where to purchase.
