They are fairly new and unused and look like they could be a fairly expensive pair of binos. Does anyone know how good these are considered and how much they generally run? I traded a small mount for them so not a lot was invested. -------------------- Astronomy educator Sidewalk astronomer 18 inch f4.42 dob on eq platform w ST120 f/5 finder 8 inch f/6 dob 8 inch f/8 eq planetkiller William Optics red 10th Anniversary 80mm FD 24lb eyepiece box Cernan Space Center astronomer Member of Northwest Suburban Astronomers Edited by Darren Drake (12/22/07 01:55 PM) Post Extras:       Mark9473 Carpal Tunnel Reged: 07/21/05 Posts: 2663 Loc: 51°N 4°E Re: Adventuridge 10 x 42 waterproof binoculars [Re: Darren Drake]       #2068042 - 12/22/07 02:05 PM Edit   Reply   Quote Quick Reply   They look nice enough. How's the viewing? Do they have phase coating?

Anyways the box says waterproof/fogproof, nitogen filled, long eye relief (about 20mm), lifetime warranty, and a few other things. The eyepieces have about a 55 degree fov and the images at the edge are pretty sharp. No mention of phased coating. What is that BTW? Thanks. -------------------- Astronomy educator Sidewalk astronomer 18 inch f4.42 dob on eq platform w ST120 f/5 finder 8 inch f/6 dob 8 inch f/8 eq planetkiller William Optics red 10th Anniversary 80mm FD 24lb eyepiece box Cernan Space Center astronomer Member of Northwest Suburban Astronomers Post Extras:       Mark9473 Carpal Tunnel Reged: 07/21/05 Posts: 2663 Loc: 51°N 4°E Re: Adventuridge 10 x 42 waterproof binoculars [Re: Darren Drake]       #2068121 - 12/22/07 02:53 PM Edit   Reply   Quote Quick Reply   That's surprising, I never heard of a 10x42 roof being sold through Aldi. Phase coatings are explained here. The short summary is that it's what you need on a roof prism binocular to get an image as good as in a porro prism binocular - all else being equal. Today it is also what separates cheap roofs from mid- and upper-level. -------------------- Mark Leica 8x20; Vixen 8x42; Swift 8.5x44, 10x50 and 20x80; TS 7x50; Orion 15x63 WO Megrez II 80 FD + Baader 90° T2 Amici Post Extras:       hallelujah Carpal Tunnel Reged: 07/14/06 Posts: 1636 Loc: Colorado Rocky Mt.

How much of a difference do they really make? What does this usually do to the price tag? If the box doesn't say phase coated does that mean they are not? ....And are they all made equal or is there variation in their quality?

They do make a substantial difference. Yesterday's $1000 roof binocular without phase coatings is easily beat by today's $400 model that has it. Again, just a personal opinion.
