I have two sets of binoculars 10X50 and 7X50. I prefer the self focusing
7X50. I find the self focussing very easy to use in day light. At night
with moon light the 7X50 are fair. Conversely the electronic binocular are
better for night vision. However they get impaired by certain colors like
green, yellow and at time shiny white and consume battery power. The
consensus tends to be in favor of the 7X50. Some boaters prefer the 10X50.
Most important is how the binocular are sealed. My 7X50 are filled with
nitrogen and sealed as per MIL. specs. They do not get fogged up inside
and the vision is not affected by inside condensation. My 10X50 are not
build to MIL specs and condensation builds up inside. So I clean them
regularly inside out or I leave them inside the house.

I'm sure this is a matter of opinion, but I would tend to favor
the 7X50, only because any type of motion makes the larger
magnification (10X) hard to deal with.

If magnification is all you are concerned about, than 10X with Image
Stabilization - as Jeff mentioned in his reply - might work for you.

They will also be easier on the eyes during daytime use than the 7X50's
(see below). Check them out at a dealer.

If you are planning to use them at night for navigational purposes, I'd
recommend the 7X50's. They have twice the light gathering power of the
10X50's (it's the same reason that 7X50's are preferred over 7X35's even
though the latter is lighter/smaller) and, as you've already mentioned,
are easier to keep steady compared to bincos with 10X magnification.
