Had a chance to try out the new binoculars in varying conditions over the weekend, so figured I should report back. For those who have not read the thread, we already had a pair of Nikon OceanPro 7x50s. We bought them in 2001, and have been very happy with them. During our 9-day cruise I accidentally dropped them off the helm seat which caused one of the prisms to go out of alignment. We have already been in touch with Nikon and are sending them in for repairs. In the mean time, we decided that (a) we don't want to be without a pair while Nikons are out for repair and (b) we really need two sets as my wife and I use them all the time (both for navigation and watching the shore/wildlife).
The new pair are Steiner Navigator Pro 7x50s. These are the middle of the line Steiner marine binoculars (between the Mariner and Commander series). They were about $100 or so more than a new pair of Nikon Ocean Pros. Now to the review.
In mid-day light, we didn't notice much of a difference from the Nikons. The view seemed a little more sharp, but that i likely because the lenses were factory new and clean. I did notice a little less glare, likely due to the new coatings. Where they really shined was in low light (dawn and dusk) and at night. I do believe the light gathering is a little better than the Nikons - not a huge amount, but a little better. Keep in mind that I have not been able to do a side by side test, and won't be able to do so until the repaired Nikons are back. One feature I really like is the dual diopter settings. I wear glasses and my wife does not. I generally take my glasses off when using binoculars as I like to put the eye cups right up to my eyes to block out surrounding light. Once I played with them and found my perfect diopter setting, it made it really easy to set and forget. Then, when I pass them to my wife, I just zero them out. When she passes them back, I just turn them exactly to my settings. Nice feature and much easier than refocusing every time we pass them off. Overall, I'm very happy with the purchase. No idea how much better the Commanders would have been, as we ordered on line without trying them. Also, I didn't want to get into the Commander price range. Again, thanks everyone for all the advice and shared experience.
