The directionality surprised me for a 12 inch dish... I can be 20 feet
from a three level fountain, each level being about a foot or so higher
then the other, and I can hear each level fade out, as I center the next
level. I have no doubt that I could pick out an insulator on a pole
with many insulators.
I tested it on a sprinkler head, (if you want Ultrasonics, use this
method), and from 30 feet, if I aim it off one foot or more from teh
sprinkler head, the level drops significantly.
Also thank you for the complement on the web site, I try and keep it
simple and easy to understand and read. I assume the navigation was OK
in finding other reviews? If not, use the Categories menu on the right.
That will show you the various reviews based on subject. To see all
reviews use INFO.

I can melt ice with my mind... Takes a few minutes though...
