7x50? Fujinon FMTRC-SX!
If you are not concerned with weight, these cannot be beat.
At the time, I was doing quite a bit of offshore and near-coastal sailing and lake racing. Research kept pointing to the Fujinon for the unsurpassed reduced light and night qualities, and the rugged construction. These were designed for marine use, rubber armored, and are heavy (about 3.5 lbs).
I originally had a pair of MTRC-SX for a few years. In the late 80s, the "F" (Flat Field - larger diopter for wearing glasses) model appeared. I sold the MTRC and got the FMTRC-SX and have not regretted it. The integral compass has been quite useful in the field, and they have a Mil based stadia.
It's always interesting after the evening hunt when we gather after dinner. Guys start dragging their Zeiss, Leica, and Swarovski binocs out to check this one feeder that we don't hunt. They are all amazed after taking a peek through this glass in the dark - I still am.
