I owned a pair of Fujinon MTR-SX 7x50 for almost 30 years using them from the northern Atlantic to the
Caribbean and, despite their heavy weight, it is still the best binocular I ever bought.
5 years ago, I bought a
cheap pair with Steiner looks ( you can find them under different name: Barska, Celestron, BetaOptics ...) all the same, lighter, poor optics , a specially at night and really fragile. One of the eyecup fell apart after 1 week, then the
compass started leaking,finally, the rubber coating became gummy and fell apart.
Thereafter, I bought a pair of Steiner Navigator Pro, I would say these are good quality/price binocular, lighter than my Fuginon, I would say as strong ( used them for two years of extensive cruising in the Caribbean), the optics is not as clear at night as the Fujinon but my wife prefer their weight.
My personal recommendation , invest in good quality and think long term.
