Hello all, just registered and the first post. Can your knowledge come to my rescue, please? I now live in Cyprus and have been approached by a company to do professional bird surveys so it is time to upgrade my bins. I have done a tonne of research but am still undecided about what to get. My wife has agreed to let me spend 500 pounds but is prepared to go to around 900 if the pair get is so much worth it. At the moment I am swinging between a new pair of either Vortex Vipers or Monarch 7's or second-hand Zeiss/Leica's. Bear in mind although I will be doing dawn/dusk surveys, Cyprus has no shortage of sunshine and is rarely cloudy I was wondering if anybody can recommend the right pair for me? Finally. I do tend to wear glasses when surveying. Thanks in advance for any response.
