If you plan to go for jungle trekking or river cruise, item that u must bring along is your digital camera which has a higher optical zoom and a binocular. I have a 12X zoom digital camera. Until now, I am still very satisfy with it since I have taken a lot of great photos by using the zoom, especially during my recent trip. However, I do not own a binocular.
I checked on the website and found this: Nikon Monarch ATB. It is a waterproof binocular. Besides, it is also shockproof and fogproof. It comes with an ultra-rugged, rubber-armored and roof-prism design. The best part is, Nikon Monarch ATB has a 25-year limited manufacturer warranty. Check out this binocular and maybe you will like it as I do.
