Binocular Decisions

Hey guys,

So I have narrowed down to two binoculars that I am wanting to buy but can't decide on which one. Vortex Diamondback 10x42 or Nikon Monarch 5 10x42
Has anyone have any opinions or advice on the two?

I JUST picked up those exact DiamondBack 10x42's from Cabelas through their sale for my boys Christmas Present. Our other bino's are Nikon Monarch's... been happy with them, but IMO the Diamondbacks are better. Had both Monarchs sent in to fix the eye cups, Nikon fixed them for free under warranty and sent'em back.

PS: Cabelas had a optics sale on their website that put the Diamondbacks sub-$200, I then just had them ship to store where I picked them up). I dont know how much cheaper you can get on them honestly, figuring in gas to drive around etc etc.

LAst time I ever tried to get a deal like that the line went from Cabelas front door, up the north sidewalk, then east past the loading bays... then north along the fence about 100 yards. Enough people rushed in they stopped letting people in for 20 minutes... enough time those inside snapped up all the good deals. I had gotten their early... there was not enough stock for even the first 50 people in the door.

Never again. Blackfriday ad's are like ad's for lottery tickets. Sure you might win, someone always does, but its a poor waste of time / money.

Comparing a pair of binoculars with a 42mm objective lens with one that has a 50mm objective lens as far as letting in light is like comparing a flashlight with almost dead batteries with one with brand new batteries.

Any binocular with a 50mm objective is going to let in a lot more light than one with a 42mm objective, I don't care what brand you are looking at and it is dumb to even consider the difference.

One thing that you haven't considered is that the 10x42 binoculars weigh less than the 10x50's. So does that equal out the difference in light gathering capabilities of the 50mm objective vrs the 42mm objective?

What good is a 50mm binocular objective if you have a 40mm rifle scope objective? Think about it... ;-)

There is a mathematical formula to determine how much light an optic will transmit to your eye. simply divide the size of the objective lens by the magnification. for example a 10x42 (whether it be a binocular, monocular, or scope) will have an exit pupil (the size of the dot of light that passes through the optic and enters your eye) of 4.2 mm. a 10x50 will be 5mm.

No experience with that particular Vortex model but have been running some Nikon Monarchs for about 6 years. I too had to send them in under warranty to get the eye cups fixed. It took about 2 weeks but wasn't a huge deal. I thought I had some decent glass with them until I looked through my Dad's Leica Geovids. Now I'm saving up for better glass. If that's what the funds allow either one should work for you. Compare them side by side of you can and see what works best for your eyes.
