PISCATUS BOTTOM CONTOUR MAPPING....Note.

As the boat travels along it gathers information from
the GPS and Depth Sounder, then a powerful onboard computer crunches the numbers
and produces a contour map of the bottom, this info is saved and added to,
every time the area is visited. This is all viewed on a 17 inch screen. The
boats position can be seen, so it is easy to head back to where the fish are,
well were. Its a "well informed" very busy Cockpit. You can spend an awful lot
of time looking at this, as it is more than interesting, takes you away from
your fishing.
This is how it works, the GPS sends a signal "as to
where you are" to the Sonar, and it sees the depth, then both signals are sent
to the Computer, it draws the Bottom Contour Map, Colour indicates depth,
Viewed in 3D. It knows where you are and remembers every time you visit the
area and up dates the Map.
These are some of the tracks it remembers, and I can
go and look at the these current / past tracks, as it is updating, it does show
if we have been in the area before, as it all ways adds the fresh information.
Its a little like a road map in 3D.
This is a scattered wreck, not a lot left of it. but
then the shot is zoomed out.
This is what the sounder sees although it does not
remember it. And Piscatus does not see the fish. So its a situation where you
need marry the two together, that peak at the bottom Left is a propeller
standing up E to W, and on the right is it N to S it with some ropes and buoys
hanging off it, the rest are small fish.
This is a Reef area off Catho, the area to the
left of the boat is a cave. Mmm good fishing.
This is the Farm, it is actually a drop over of about
17 to 20 meters
This another of off Catho, zoomed out and showing the
shore line.
This is a shot of the Shelf where all the Marlin are
caught, the water here gets very deep, and goes from 155mts to over 1000mts.
this is about 52km out from Swansea heads and also Newcastle.
Another Shelf is further out goes even deeper 5 plus km
deep. Well it shows where you are, and how. Consider if you are in the boat and
where the boat actually is, makes it easy when fishing.
This is the Redhead Wreck you can see the bow of the
Vessel, the area to the left has not yet been drawn by Piscatus as we had not
yet been over it. the holes shown are 6mts deep, and do hold some good fish.
These Colours I no longer use. Was early Days, and just playing, well seeing
how it all works. The small boat on the surface represents the Mapping
boat (Paulus), it shows where you are and direction you are heading, it also
shows distance from the screen curser, so you know how far you have drifted
off.
Below is Texas area that is about 32 km south/east of
Swansea
This is a zoomed out shot of the lake, I am sure the
boat is just off green point, at the trench.
This is the area around Moon island
This is in the lake, a deep hole can get to 15 mts deep
This is just out from the Croudace Bay boat ramp
I will add more
