Product Information

From my garden I watch birds, boats and ships at sea, sport at the nearby school and the cricket club, all from the comfort of a deckchair overlooking Torbay, and south towards Brixham. This allows for the highest level of light intake and results in brighter, crystal clear and razor sharp images. Given hindsight, I might have sought to compromise and get a little shorter minimum focus distance, maybe getting less at the other end.

As well as being a formula that yields the zeros of any parabola, the quadratic formula can also be used to identify the axis of symmetry of the parabola, and the number of real zeros the quadratic equation contains.

I do find that my 15x70s, though they give better views than the 10x50s, are that bit harder to use in part because of the reduced FOV. In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.A binocular’s objective lens diameter (listed in millimeters) shows the width of the front lenses (the side closest to the object being viewed). Features such as their soft-touch grip pads put them a notch above the rest, and everything looks better through bright, clear, fully-coated optics.
