One of the most forgiving scopes I've ever used is the Leupold 6x42 FX3. It is so easy to get along with that it's hard to
do anything wrong. It doesn't seem to matter much where your eye placement ends up, heck you might be able to do cartwheels and still see through the scope. The 42 mm lens will still produce a 7mm exit pupil, which besides providing lots of light gives a larger sweet spot to align your pupils with. That's the biggest reason marine binos have moderate power and large objectives; it makes them useable on moving boats.
      There's a AO version, with turrets if you feel like you need those features. It was made for Hunter Benchrest.
