Hi.I have used a lot of binoculars over the years and currently use Nikon 10x30's. To see ship names, IMO's,funnel details etc you need a really delicate focus and fine lenses which the Nikons have, even though I have had zoom lenses and higher magnification binocs in the past the Nikons are the best. I like them because they are small, light, inconspicuous (which depending where you go in the world can be important!)and the case fastens to my belt. I have used them shipspotting both in the UK, in Europe and in the Far East both from land and on ship (Although they are not waterproof), the only disadvantage for me is that due to the small lens diameter viewing in very poor light is not as good as the larger lenses which let more light in. When buying I would ask to take the binocs outside if possible. Pick a street sign or similar well out of sight- Test the ones you like on the sign and see which are best. I have found the better make and perhaps lower magnification to be the best. I have also found that whatever the magnfication there are always ships out sight. Hope this helps. Regards Steve
