As the development of the
USA units continues, we have performed a underwater
demonstration using many new advancements of the USA
antennas and technology.
We started the day off by
selecting the 6 Foot Antenna to go with our adventure
along with the USA Discovery Control unit. The 6 foot
Antenna is equipped with (8) High Sampling Sensors that
are capable of traveling high rates of speed.
To give you an example,
we were given a tip regarding an old sunken structural
bridge at the bottom of the lake (approx. 100 feet or
more) We ventured on a (1) Row Scan traveling at a
constant speed of approx 30 MPH.
We then started the underwater scan allowing the
sensors to ground balance to the surrounding environment
variables (i.e. the water's surface area.) We set our
software settings to a length of 200 (one of the highest
settings of length tested so far). As we were scanning
we noticed mass changes in the software's 3D imaging
contours, and the sensors were responding according to
plan. When the scan was finished at the 200 length from
within the software, we then took the scan and rotated
the image to show more detail from a lateral perspective
then to an oblique mode perspective.
The Flat rotation of the
image portrayed a very high detailed image regarding the
sensors response of the highly-mineralized silt at the
bottom of the lake, then continued to a sunken
perspective of the underwater bridge that we were
looking for. From that point, I then turned the image to
the "Oblique" angle in the software to show a more adept
view in 3D still containing the same colors based on the
data received.
At this point in the day, the weather
was hot but we still continued to make the most of this
technological breakthrough of equipment and ease of use.
We ventured further across the lake to start the second
scan of our adventure. We then set the software this
time to a smaller size of scanning area, (50) sped up to
a constant speed similar to the bridge scan, started the
software once again to cause the ground balancing to
take effect and began scanning. To our amazement when
the scan completed, we noticed a huge difference in the
software that we hadn't seen yet. We saw the values in
the image (blue) as a bottom of the lake channel that we
were traveling upon turn into a high reading of magnetic
qualities. (Red) We couldn't quite explain by definition
what it was that we saw. To our amazement while
capturing photos of the trip through the lake channel,
we noticed the mineralized surrounding hillsides that
seemed to continue from the left side of the channel to
the right side and guess what? This high concentration
was that of very highly mineralized iron-like soil, silt
and rock that continued right under the boat and
directly under our sensors.
Once again, in the midst
of testing and development, we have determined again
that the uses of the USA never ceases, first by proving
a tip of a fallen structural bridge decades ago, does
really exist, to a highly concentrated mineralized belt
that could prove useful for precious elements mining.
And at the end of it all, as sophisticated as this
equipment is, the ease of use was beyond amazing. Enough
so that we soon agreed we would be back. This time
bringing more advancement of equipment and more gas for
the boat.
