So, I got the 15x50 already for about 15 years on my ship in use and am still thrilled. While there are still on the ship a zweites- very gutes- device with compass and 7x50 (every sailor will know), but that is, since I have the Canon used only sporadically. The negative points of my previous reviewers I can only emphasize but that Sehergebnis make these points still up for it. Very I am also in the meantime but considerably more favorable price, I'm still at that time converted nearly 2000, - Euro paid. What electronic device under the harshest conditions is already working such a long time without complaint? This investment has been absolutely worth it.
