  1. This is the reason why I have been giving much importance to the "KJ factor" ever since. There is no chance of counteracting a force of KJ 4 and above when diving with the kind of buoyancy required for bottom searching. If you find yourself in an open spot with no obstructions to the flow of currents, it is best to start emergency procedures early. So the first essential check before a session is wave energy. For no reason do I approve a day with higher KJ, other than 0/1/2.
  2. Hard not to remember mermaids, I have one tattooed on my chest, right after a bad day when I was trapped far from the shore without bcd and fins, overwheighted in an invisible and strong current.A good scare and a lesson I won't forget.It was 2014, a week before my daughter was born.If I didn't die of fright, it was close.
  3. Well, speaking a little more technically about what happened I think I tracked a piece that because of its shape and weight, stayed where it was lost in deeper water. Almost all of the pieces I pulled up in that spot were in the first drop off with smaller weights. The pleasure I am getting with the D2 is intercepting broken bracelets and necklaces that overall make weight. Rip tides however are something I look out for. Although I am pretty heavily weighted, I can feel the displacement barely getting under control and at that point I resurface.
  4. Believe me, if it weren't for over an ounce collected at that spot, I wouldn't even plan to go back there, given the difficulty in reaching the shore from the parking lot. On Monday I start hooka compressor testing and I think I will have to go back there again....
  5. After the usual three days of weather observation and skipping scouting to confirm bottom conditions, this morning a window of about 3 hours presented itself before new wave energy made the spot where I thought I was done in October impassable... The few remaining signals, are items I have not picked up due to the lack of a net bag, but whenever I find myself on a target I know, I am able at that point to isolate areas where I have already passed in other previous sessions. That said, the day started badly with leaks at the 'air regulator and missing pressure in the tank. I manage to hold the bottom for just 45 minutes and am forced out on emergency for low air. I reach the car by traveling about 400meters with the harness and ballast on and change the cylinder. At that point I screw the first stage back on and open the 'air tap on the new cylinder and hear the unmistakable venting between the tap and the first stage. I unscrew again and notice that the O-ring has blown out. I find it intact on the ground and reassemble correctly. After all the time wasted, I wonder at that point if I should leave the beach, since no interesting targets have come to light and I think I finished already in this spot some time ago. I decide to persevere and although I don't feel like walking with all that weight, I return to shore and dive. A strong current pushed me to the side just before I went out to change my tank, and this time I follow it, letting it carry me slowly toward deeper water. At that point a signal among the 40 draws my attention and a moment later I find this unusual ring in my hands.... Lesson of the day? Insistence can pay off even when it seems over....
  6. I can totally confirm your impressions and we own practically the same instruments except for a pulse and a 2.4kHz single-frequency with concentric coil. I found in the D2 the depth of detection that I did not have on the Ctx with the same coil. Regarding the balance I think it is relative and if you look at the numbers in saltwater, a strange 70/85 range appears, when in fact the rocky/clay bottom is on the 25 and in fact that is the false signal to be shot down. Exactly this makes the D2 different from an Excalibur or a Ctx: more sensitivity and depth and I mean on thin and broken things too. But since I am unashamedly clear and no brand pays for my reviews, I also say that for a saltwater diver, it is not really the ideal instrument except with so specific settings that I struggled to find by trying and trying again. Another point in favor of the Ctx is also a more effective id scale in "isolating" the gold, because by comparison on the D2 it is scattered pretty much everywhere between 27 and 70.
  7. Sorry but i forgot an easy and old test in my previous answer... Have You tried with a magnet to pass over the chain?🤔
  8. Ultimately I see no rust on the links. It could be plated, however maybe because of the low light it does not have that typical shine. A wire cutter might reveal a hollow link or some copper inside, and if you don't feel like breaking it, only a jeweler can reveal it.
  9. This is actually a suspended project from the past. I used a 6.5Hp motor pump and differential diameter piping to raise the pressure and get more suction. I didn't need the sluice because I placed a fine mesh net in front of the nozzle just in case I saw some rings sucked upward. This kept the pipes clear of stones and suction always powerful. Problem is that dredging remains one of the operations for which permits must be obtained before starting, and the use of mechanical tools along the shoreline is not tolerated. At that point my dive buddy and I at that time, used dpvs to level the layer but the battery life is penalizing...Obnoxious then, having to leave the excavation point without boat and gps and then return to shore, change battery and tanks and return as navy seals to the hot point. I am waiting for an expedition with a corded breathing device similar to Brownies' Third Lung to at least eliminate the clutter of cylinders and transport the dpv, which I convert to lithium, on a floating cart. It will be another month before testing, unfortunately.
  10. Finally away from a summer season in which I did not even touch the water, the time has come for the first storms, and right now thunderstorms and threatening waves are hitting "my" coast. So all that remains is to hope for the opening of a few spots with a reduced layer. It often happens that something goes wrong and, for the purpose of removing sand, the storm brings more. At that point heavy strategies and calculations begin. Several years back I went so far as to build a dredge and test it successfully, despite not finding any interesting material in the same spot. Constant breakage due to salt water and corrosion make the equipment fragile for continuous use, and too many times the expense of repairing it does not pay off. Abandoning the massive excavation project, I went through the use of a dpv and came to the conclusion that darn it, no one operates as effectively as Mother Nature. Numbers matter, whether you are mining fine powder or nuggets in the form of rings, if you don't explore at least 100 square meters in 3 hours, you don't even have a clue what the bottom is really like. These are not exact figures, but a rough idea of what it means to prepare what is necessary and how much to expect in terms of results. No photos at the moment, I reinvested the (little) material collected in October for a setup change, hoping to improve the effort/output ratio.
  11. And it is the cause of so much beauty. Pieces like these are seen less and less, and to give them away as scrap is sorry, but necessary.
  12. After a busy October in a spot I wouldn't have put a dime on, I returned after doing two more sessions on another stretch of coastline and returning home with coins and steel bracelets ready for the dustbin... After more than an ounce here behind me, now certain that I have checked 99 percent of the small gulf reduced to pebbles and clay with a veil of sand, this little pendant closes the party and wraps up November by now as more serious storms loom and I move away from the bottom. I'm starting to take serious note of data and timelines, because while it's not an exact science, the puzzle is composed of too many factors, and creating a pattern intrigues me. Have a great sunday you all.
  13. It sounds really inviting as a start🫢... A good reason to go back and explore again.
  14. Heavy stuff...Interesting area...Go back there as soon as You can🤞
  15. Exactly. When you have at least one landmark, you can dissect an area and eventually go back after you have ruled it out. Although I only hunt in the water and years ago I left an army of other hunters on the shore to do pro bono retrievals, at least three times I ran in the middle of summer, with the beach full of people, carrying a harness, 15lt tank and a couple of detectors. To do what? Ask the lifeguard for assistance and keep people away from the spot that was described to me, find a bottom chock-full of aluminum and fresh drops of any kind less than metal, come out about three hours later with a host of onlookers waiting for a result and say...Nothing, I found nothing sorry. At that point it is a matter of explaining a reality that people do not understand. No one likes to trip over rocks while trying to get into the water for a swim, so clear waters and a soft bottom for walking are chosen. Too bad time runs fast and any piece disappears swallowed up in the blink of an eye, assuming you are in the exact spot. Even a current on flat clay can do crazy things without the water appearing choppy on the surface. So I stopped with on-call retrievals.They think I'm putting something in my pocket by not paying myself, but on the contrary I'm losing time, diesel, air and maybe someone thinks I'm keeping their stuff for myself! In Europe there is just no culture of paying back an effort.Sad.
  16. Three out of four found again is an outstanding achievement! I hold the reverse record in finding any other piece I am not looking for on specific directions from the unfortunate. Almost no one has a clear idea of where and when they lose the stuff.And when you get specific instructions, it remains to be seen if it's not what they believe to be real and what happened on the beach immediately afterward.
  17. It's part of the game.Even with the best conditions, it can always be a spot that has been beaten before. On the other hand, last month I produced almost an ounce in a spot I wouldn't have put a penny on
  18. I've been faster than tides but someone else was faster than me cleaning the good stuff😑. Like i wrote, I just found lot of lead and some coins.
  19. Unfortunately, the exception to the rule struck. In spite of an almost sandless and dismantled bottom, I found nothing but quite a lot of lead and a few coins. Being very light with only a ballast harness and snorkel, I was able to move and search for a long stretch of beach but the farther I got from the point of maximum erosion, the worse the signals were, reduced to only shallow or deep aluminum and therefore badly sanded in...
  20. Being a diver, I'll do this morning a snorkeling session to check the surrounding area under the cut.There's just a couple hours window but without any doubt this is prime ground. When Mother Nature shows you the foundations of the beach, the variations are two: either you take it all or someone has already done it.So, crossed fingers...
  21. While scouting this morning, I came across a stretch of coastline and... You know what I mean.
  22. For sure stainless steel type isn't cheap but on the other hand those last quite some time.
  23. Well, let me know how much you get paid for a pound of product🫢
