We bought this product specifically for marine use on our boat. They are well made, comfortable to use with non-slip grips and a light to see compass bearings at night, useful if trying to ascertain a heading to other vessels, landmarks etc. when light is limited. I am not sure that the individually adjustable eye piece lenses is that beneficial as the binoculars are obviously shared between crew members and a single central quick adjustment would be easier with variations on one lens. This is why I only rated it 4 *.As yet we have not used them in anger, (i.e. at sea winter is not the best time for sailing in UK waters!) so will update when we have had some "real" use. However, based on some bird watching and scenic viewing they provide clear images with a good field of view.

Il prodotto sembra di buona qualità e costa molto meno che su altri siti, dico sembra perché l'ho solo avuto fra le mani ma non l'ho potuto usare in quanto è arrivato con un oculare staccato videntemente danneggiato nel trasporto. Il venditore è stato gentilissimo ha organizzato la restituzione è mi ha rimborsato. Per questo merita 5 stelle.
