Also, they are much heavier in the bigger magnifications

and also consume batteries, with some models going

through these at an alarming rate.

Bottom line – if you can afford the hefty price tag, and

are prepared to look after it properly, an image-stabilised

pair will give you the highest magnification. But for most

recreational boaties they are probably hard to justify.

OBJECTIVE LENS SIZE

The second number specified in a binocular spec is the size of

the objective lens, which is the lens furthest from your eyes.

Large objective lenses gather more light, which will result in

a brighter and clearer image. This is particularly important

if you plan on using your binoculars during early morning,

dusk or night-time.

Larger lenses mean bulkier and heavier binoculars.

Since you’re not usually carrying it any distance, the weight

is less of an issue, but holding it for long periods of time

can be tiring on your wrists. Most marine binoculars have

objective lenses of 30mm to 50mm.

FOV OR FIELD OF VIEW

The FOV – also called the Angle of View – is the horizontal

measure of what you can see when looking through your

binoculars, and can be specified either as a number of

degrees or a measurement in metres at 1000m.

For example the Minox BN 7x50 DC Nautic marine

binoculars has a field of view of 123m at 1,000m (or 7.1°).

ABOVE Light, compact and

easy to handle – less chance

of your wrists getting tired.
