I've always wanted a pair of high-powered binoculars but seem to have trouble focusing. My hands shake, particularly when I'm in a moving vehicle so the view I get seems blurred.

You should try Canon's 10x301S image-stabilising binoculars. They're light (600g), compact (127x150x 70mm) and easy to use. Even on a rough road or in a boat, they give a clear image of the object you are looking at.

How do they work?

The image stabiliser requires two AA alkaline, lithium or Ni-Cd batteries.They power a unique mechanism of prisms linked to gyroscopes. Simply by pressing the image-stabilising switch you'll get a clear image at 10X magnification.

What happens when the batteries run out?

Then you're left with an ordinary, but superior, pair of binoculars.

Where do I get them?

The Canon 10x301S binoculars are available by mail order from Nauticalia on 01932 253333. They cost £360 plus £3.25p&p per order.
