The main feature of the Spot-On Sundial is the divided gnomon*
constructed of two parallel plates with a small air gap. This
permits a ray of sunshine to pass through for a few minutes at
This makes it easy to set up from a table supplied with the sundial.
It also gives an "event" (like the noon cannon without
the cannon!) each day.
As one of our early customers said "It's like having your
own private Stonehenge in your garden".
The Spot-On Sundial can be used indoors or out.
The rotating dial plate allows the use of the dial on an indoor
window-sill; the baseplate is pushed against the window frame,
and the dial plate rotated so the sun shines through the slit
on the centre line at solar noon. The centre screw is then screwed
down to hold it in position.
For use outdoors, a level plinth is established, the baseplate
is screwed down to the plinth, the rotating dial plate set on
the baseplate, aligned exactly at the next convenient solar noon,
and the screw tightened to hold it in position, as described in
our setup page.

the shadow. It is derived from the Greek word meaing indicator;
the g is silent, so it is pronounced "no-mon" with the first o
