I had a pair of the Nikon Travelite 9x25 Mark IV binos for 14 years before dropping them once too often! They had been great - light, easy to use and with a bright clear image. This new pair are just as good with a very sharp bright image and very easy to focus, with the added bonus of being waterproof and hopefully a little more shock resistant. They also have a useful lense cover to keep the rain and dust off when hung round your neck. These binos are every bit as sharp and clear as other much more expensive pairs that I've tested - and fantastic value - I love them!
