What part of Sussex County are you in? Wife and I used to have a 2nd house in Millsboro, so I'd hit the beaches with my Sovereign Elite every weekend for over 10 years, mainly DE beaches like Henlopen, Tower, Fenwick Island, Indian River & Coin Beach, but would occasionally go down to OC area. I'd wade in the water with my Sovereign no deeper than my knees as my Sov isn't waterproof and if I can't see my feet, then I can't see anything that might be swimming around me, you know what I'm talking about, lol.
But now I've added an X-Terra Elite so it's fully waterproof so I can go deeper. But still, I just don't like the idea of going deeper into water where I can't see what may be lurking around me. That said, there is another beach next to Henlopen I used to frequent. You can wade into the water pretty deep; it's in a protected area so no waves to deal with. That's the beach where I learned years ago that my brand new AT Pro wasn't waterproof. It's supposed to be, but as soon as I submerged the control box, the screen flickered and then it was dead.
That's also the beach where back in 2011, I made my most interesting find. It looked like some type of makeup brush when I pulled it up, it was a black tube with bristles on the end, so it looked like some type of brush. When I got back and started cleaning it, the "brush bristles" came off. It wasn't bristles from a brush but some type of sea growth. This thing was about 3 or 4 inches long, and there was a red light flashing at the end of the tube through a clear lens. There was a company, model number, and serial number printed on the tube. I did a search on the model and saw that it cost $125.00 at the time, so I'm sure the owner would want it back.
So, I contacted the company, gave them the serial number, and they contacted the party who purchased and gave them my contact info. A few days later, I got a call from the Director of Aquatic Studies at the Univ of Delaware. The thing I found was one of their scientific instruments that they use to document migratory patterns of fish. They had it attached to a Coast Guard buoy out in the ocean and when a hurricane came up the coast, it broke free and wound up on the shallow water of the beach where I found it.
I sent it back to the Univ of DE, and a week later, I received a large envelope with a Thank You/Commendation Letter from the Director and a T-Shirt, lol.
