Property me which binoculars I should buy long considered ... important for me was mainly that it seawater-proof, waterproof and - illuminated - have compass should, as I had learned during my last trip in the Mediterranean that a good glass considerably easier with compass bearings and thus the Schiffsortbestimung. Our skipper (who makes the yes fulltime) had a Steiner Navigator 7x50 with Compass. Now I wanted a recreational skipper but do not invest as much and therefore have considerable insight into "competitors". The Bresser the Amazon price of just 120, - Euros is priced absolutely unbeatable. It did not succeed with the same quality to find anything like it for the money. Also have the compass checked with another bearing compass ... no errors. The compass is reflected, so that you - not as in the other Bresser Nautic glass - this must take the eye. Red illuminated it can also be in the darkness optimally - glare-free - read. Even distances or object sizes can be determined fairly reliably. Overall I can say that I am very happy with the glass and can - especially at the price - only further recommend. Mag a Steiner maybe a little more offer precision, for Steiner is also a 10 year guarantee ... and the time just costs more than three times. But if you do not really need it, then it does not have to be a Steiner, especially since the other parameters such as twilight factor, light intensity are identical to the Steiner Navigator 7x50. Therefore my conclusion: A Supermarine glass at a truly fair price!
