Monarch X 8.5X45 Binocular

 (5 customer reviews)

I was recently forced into replacing my Pentax DCF SP's as a result of theft. Instead of just buying the same model, I decided to do some comparisons before buying the same ones again. When I purchased the Pentax binos several years ago they were clearly the best available in the ~$500 price range. But it has been a few years and technology and manufacturing has moved forward.

The three models I chose to compare were the Nikon Monarch X, the Pentax DCF SP (same as I had), and the Vortex Viper. Based on my testing, that would also be the order I'd put them in from best to worst.

Ability to resolve fine detail:
This is based on observing resolution charts that allow an accurate comparison, and are the same charts I use in testing my high-end camera lenses. The Monarch X was the winner. The Pentax SP's were very, very close, but not quite as good. The Vortex Viper, although more than $100 additional, was a distant third. I was surprised. I really...Read more

I looked at binoculars costing many times the price of the Monarch X, but couldn't see the difference. These are extremely good for birding in low light situations, such as dusk, or trying to resolve a lurker in jungle growth. The optical quality is sharp and clear from edge to edge, with no visible distortion, quick to focus. They've been dragged through downpours in Kauai and Ecuador, and ended up floating in a flooded boat cabin, proving to be truly waterproof. Perfect? No. The objective lens covers want to spontaneously detach from their attachment points, so I end up removing them and leaving them behind, which defeats their purpose. The eyepiece cover is equally irritating, and had to be tethered with a piece of string. It attaches to the neck strap, but not a harness. After seven months of intensive use, I'm pleased with their performance and durability.

This high quality Nikon Binoculars are everything advertised. The clairity in low light and stability is outstanding. I will be trying these out in Costa Rica soon and I expect to enjoy them to the fullest. Great product for the money.
