6/23/24 Report - Underwater Drone Developments. Rip Currents: The Danger and Sad News. Brainstorming and Openness to Ideas.


Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.



An animal-like uncrewed underwater vehicle dubbed Manta Ray can be seen maneuvering off the California coast in new footage captured during testing.

Sea drones are reshaping naval combat — especially in Eastern Europe, where Ukrainian forces are sinking prized Russian ships using far smaller and cheaper tech.

The Manta Ray's almond-shaped body, rounded nose, horizontal fins and vertical tail can be spotted in the 360-degree video shared by maker Northrop Grumman...

Maybe you heard this tragic story.

A Pennsylvania couple vacationing in Florida with their six children drowned Thursday afternoon after getting caught in a rip current, local authorities reported.

The family of eight was visiting Stuart Beach on Hutchinson Island – a barrier island located on Florida's southeastern coast – when the parents and two teenage children were swept out by a rip current while swimming, according to the Martin County Sheriff's Office....

Rip currents are for real, and they are a real danger, especially if you don't know how to get out of them.

I remember getting caught in a rip current three times while metal detecting  The first time came as a real surprise.  I didn't know anything about rip currents yet and suddently getting caught in a very strong current was a little frightening.  Not only did I not know how to react, but it was not a guarded beach and no one was around. Fortunately, I got through it.

Having a metal detector and scoop in hand along with other equipment doesn't help when you wonder into a rip current. 

If you are not a strong swimmer, be especially careful.  If you are at a guarded beach, pay attention to the warning flags.  

Red flags indicate high hazard including rough conditions such as strong surf and/or currents being present. All swimmers are discouraged from entering the water. Those entering the water should take great care.

Rip currents will pull you out and the natural tendency is to try to go against the current, which is not the right thing to do.  Swim parallel to the beach and out of the current.  Rip currents are normally fairly narrow so when you move parallel to the beach, you will get out of it before long.  

Instead of fighting the current, NOAA advises swimmers to flip onto their back and float to conserve energy. Then, swim parallel to the shore until out of the current's pull. Rip currents are generally less than 80 feet wide, so swimming a short distance parallel to the shore can help escape the current. Once free, swim at an angle back to shore.

If you do metal detect in the water, be sure you can handle the conditions.  

Rip currents wash sand away leaving a dip that might be attractive to a detectorist.

Recently I posted a lapel pin with the name "GENTRYS" on it.  I always thought it must be a family name, but Gaylen C. said there is a Miami area high school that had a fraternity that used that name.  Maybe that is why I never found much on the Gentrys name, with the "s."   But I haven't found anyting on the fraternity yet either.

Brainstorming is a process often used for problem solving.  It involves coming up with as many ideas as possible no matter how poor or ridiculous they might seem.  Judgment is suspended until later.  The goal of brainstorming is to come up with a large quantity of ideas. The last thing you need when trying to come up with new ideas is someone discounting possibilities when all you are trying to do is generate new ideas.  An idea doesn't have to be the correct of final solution to be a good one because even a bad idea (if there is such a thing) can lead to or be developed into a good idea.  There will be time later for eliminating ideas and working out the details

See Brainstorming: Definition, Ground Rules, and Techniques (atlassian.com)

When trying to identify a mystery object, don't be afraid to suggest ideas. Even if an idea isn't the final solution, it might lead to the solution.  If you are trying to identify a mystery object, you need to come up with all the ideas you can.

Creativity isn't a common skill.  Few people are very creative and productive, while many people are afraid of big ideas that might originally sound too wild or ridiculous.  

Many today can't stand ho even hear competing ideas.  They religiously follow dogma.  They have" fact checkers," and even when they are terribly wrong, they find comfort in a community of others who are equally wrong.  They believe in absolute truths, while also believing in a "personal" or "lived" when that is convenient.  No matter how much evidence emerges they never seem to realize or admit they were wrong.

Stephen Hawking said, “Those who cannot change their minds cannot change anything.”

I'm not a big fan of Hawking, but that is an interesting quote to ponder.

Not much activity on the National Hurricane Center map now.

The surf will be pretty flat the rest of the week.

Look for a negative tide this afternoon.


Good hunting,
