What is the technique for hanging two binoculars with straps
from the same binnacle? [1 pt]

Hang them from the navigator's balls.
(Quadrantial spheres for the uniniated).


Name the two most characteristics to look for when shopping
for binoculars? [1 point each]


Lens diameter and power. Too powerful you can't hold them steady. Lens
diameter indicates light gathering capability.

All that light gathering will do no good if doesn't get transmitted due
to undersized prisms.

Coating is most important with prisms. You want to reduce loss of the
evanascent modes on the backside of the reflecting part of the prism.

use of binoculars is silly. Low light conditions are where binoculars become
useful. You aren't going to hit something a mile away in a sailboat, it
takes a good part of an hour to get that far. However in dark conditions the
binoculars gather much more light than the eye. Sailboats, thankfully are
slow otherwise they would be a real hazard to navigation.

In my opinion binoculars are not useful, if you can't see anything.
The most important factors being those that help you see what
you are looking at better.

1 point to Gilligan. Light gathering is very important. Honorable
mention to Joe and CM for pointing out quality as a factor. It's
clear that you get what you pay for.

Did someone mention stability control? I like that feature.
