I got my Newcon 7x42 LRB rangefinder binoculars I purchased off of eBay today and tested it out a little bit.
The thing is heavy but sturdy. Fits the hands well but is hard for me to hold steady enough to get readings on small objects over 1300 yards away. It does have a tripod mount though and I'll be giving that a try to test for maximum range.
The longest range I shot was 1348 on a mailbox. I couldn't get a range on a further mailbox but I don't know if that's because I couldn't hold it steady enough or if the mailbox exceeded the capabilities of the LRF.
The ranges proved repeatable and accurate when I ranged on targets at a known distance.
I suspect that this is a 1500 yard rangefinder but I will mount it and find some further targets to verify that.
The optics are good but not superb. About on par with my Burris FFII binos.

For $214 shipped I'm very pleased with this unit and I'd be pleased with the others the seller has for sale at $300.

A lot of performance for the money.

Here's a link to the LRB's Sedepot has for sale on eBay right now.
