My other half and I tried out the original RSB HD 8x42 many months ago, when they were first introduced. We were very impressed by them, with my only reservation being that the diopter required a lot of adjustment to balance the two barrels. We decided to leave it for the time being.
On Sunday we arrived at Minsmere and Lynn discovered that she had left her binoculars at home. Fortuitously, there was an Optics Day there so we took the opportunity to try out a few pairs on offer. After a while she had narrowed the choice down to the RSPB 8x42 BG.PC, the Viking 8x42 ED and the RSPB 8x42 HD. She liked the feel of the Vikings but they were about £50 more than the HDs without giving any noticeable optical improvement, so she is now the proud owner of a pair of RSPB HDs.
The view through them seems as crisp and bright as any which I tried. The size and weight are good and the focusing and eyecup actions are smooth and precise. The diopter setting is now on the right hand eyepiece and is much better than the earlier example which we tried. It was nearly in the central position after she had set them up correctly. Visually they look pleasantly clean and uncluttered but I think they could have included some sort of HD badging to make them look a little more 'special'. The lenses are now coated to repell water and dirt. They come with an 'exclusive' pin badge (not sure where you wear it), a comfortable neoprene strap, a natty little cleaning cloth in a pouch with a clip, and a good quality case with a belt loop but no strap, which is fine by me as you carry it by the binocular strap.
They come with a 10 year warranty, which seems to be the norm these days, and, assuming they are trouble free, they look perfect for her requirements. They seem to work all right, too, as she was finding birds long before me, including a Cetti's in a bush which completely eluded me until it flew away.
In conclusion, I think they are excellent binoculars which are well worth a look. We could have bought them cheaper online but, as all profits go to the RSPB, she was quite happy to purchase them from the Minsmere shop.
