Re: which binoculars ??
We've tended to use whatever the Oz version of West Marine has on sale as our day to day pair. A pair of Tamaya military style are similar in the day but definitly better night visio. Bought a pair of Canon Image stabilised late last year and although not 7 * 50 they are excellent on board in a sea. Biggest problem with the cheapies is that one decent knock is all it takes to bugger them.
The Tamayas otoh are still working perfectly well into their dotage. then again maybe that has something to do with looking after them while the cheapies tend to just hang about the cockpit.
