bud-bud, you are talking about using radar in flat calm water, not water with
movement. In anything but flat calm water you can even see a fiberglass
sailboat, let alone a submerged reef or rock.

besides, why are you wandering around in unknown waters in a fog at speed?
dumb.

I probably spend more time as
radar observer, on my week off, than you do in a year.

indeed, you didn't even know you need nearly flat water to see low rocks
with
radar, as witness your statement below:


That may have been true in the 40's and 50's. It's not true anymore.
There are all sorts of techniques modern radars use to find things like
low rocks in sea clutter, from simple ones like scan averaging and
doppler filtering to complex adaptive filters which model the sea
clutter and remove it.

Steve

All true, but I was referring to the standard everyday radar which most
boaters will be using.
Although "sea return" normally is a pain in the butt, it can be useful.
For instance, it can be used to pick up a reef line; in the case above,
it will accent the rock which may be just below or just above the
surface; I've used it to identify a particular boat which throws a nasty
wake that can be seen on radar.
All of the above are not guaranteed and depend on conditions, but when
the conditions are right they can be useful tools.

Jax, as others have said, you need to get back on your "meds".
He was NOT talking about flat calm conditions, alone. He was discussing calm as
well as conditions where a sea is running.
As he said, you don't have enough basic knowledge or experience to understand
any of this.

No one said anything about "at speed", but as to the rest, that's why one has
charts, GPS's, Radar, Fathometers, etc., coupled with the ability to use them.
Again, probably beyond your comprehension.

hey shun, he only *thinks* he is talking about water with seas, but he is not.
He is, in fact, talking about flat water. That he is ignorant of that fact in
no way changes that fact.

go back to sleep, shun.

LOL Which is it, you don't know enough about or have used radar enough to
understand how one might see a reef line or a low lying (or even awash) rock,
on radar with a sea running? Or are you assuming that since it's beyond you're
limited knowledge, it's impossible and can't be happening?

Shen

shun, you are babbling. Go back and reread the posts. Like Ragu, it's in
there.

That pretty well sums it up. You don't know what he said, don't understand what
he said, and obviously know nothing about radar observing.
BTW, he was not talking about flat calm seas and was talking about radar you
would have on a recreational boat, as was Steve.
The only one babbling here is you, but, that's all you've ever done or will do,
in these groups.

it amazes me Jax can type so well using only one hand!

no, shun, I do know what I said. I just grew tired of repeating it for your
feeble mind. It is up to you to learn, no up to me to hammer something into
your mind against your wishes.
