My husband spent several long days researching the particulars about the characteristics of good binoculars. For our main pair, we chose the GPO 10x42. He was concerned that the 10 would be 'wobbly', but the clarity of the close image is excellent from near and from afar. And the image holds nearly steady without 'stabilizers'. My husband doesn't wear glasses, and I do, so the depth of field is easily changed by adjusting the eyepieces. Focusing is easy and amazing. We are delighted with our GPOs for daytime and night sightings.
