At the top of my list is the Celestron Trailseeker. They seem to tick all the boxes with coatings, fov, etc. 48 reviews on Amazon and not a single one under 4 stars. The Opticron Oregon I have used myself and really liked that little bino. Any others I should consider? My grandpa has a small lake out his back door and he sits on the porch watching the geese and other critters. He's currently using some zoom tascos. They are not good.
JasIA,
I wasn't familiar with the Trailseeker, so I looked it up and found a favorable review on bestbinocularsreviews.com. I was surprised the specs were this good for the price point.
The Trailseeker has a wide 8* FOV, FMC, phase coatings, and dielectric coatings, and get this, a magnesium body. My, my, that's a load of upscale features not usually found in a roof costing only $219! If the view is sharp, this bin might give the venerable Blue Sky II a run for the money. Better check it out, Frank. You might have another 3-year thread in the works.
I couldn't bother to wade through all the usual basic education sections that he always has on every review, so I skipped down to the Image Quality section and read a one-liner that surprised me:
"Whilst there is some blurring of the image right along the edge of the view, it is negligible and no more than the best in their class."
An inexpensive, WF Celestron bin with a big sweet spot unlike the Japanese-made Celestron 8x32 Ultima or the Japanese-made 8x32 Noble, both of which had "crummy" edges?
He also didn't notice any excess distortion (pincushion or "barreling"). That's also VG.
I like the shape, too. The "high-bar H" style, with the bridge set back near the EPs for more room in between the barrels for your fingers.
I tried the Prostaff 7 8x42, in fact, I tried Jerry's Prostaff 7 8x42. It's very long, good for big hands like mine, and I liked the view better than I did the more expensive 8x42 Monarch 5. However, the P7 doesn't have dielectric coatings, nor a magnesium frame (polycarbonate). The edges are VG, but the FOV is only 6.3* so that's not as hard to accomplish as it is with an 8* FOV bin like the Trailseeker.
Based on the review, I would check out the Trailseeker. Your grandfather would probably prefer a wider FOV since it makes it easier to find birds and wildlife, and it's smaller size would probably make it easier for him to hold and carry.
Does he wear glasses? The ER is listed as 17mm, but that doesn't mean all of that is usable since eyeglass design and eye socket depth vary from person to person. The P7 has been discontinued but replaced with the P7s, which has a wider FOV (6.8*) but still moderate compared to the Trailseeker.
I would go for the Celestrons and buy them from Eagle Optics or another store with a generous return period so you have time to check them out to see if you agree with the reviewer, who gave them two thumbs up.
Here's the review:
