The silver umax is salt water tolerant........

gizmo....don't be surprised if someone disagrees with you (but then again DC3s weren't supposed to be able to fly with one wing missing outboard the engine nor are you supposed to be able to roll 707s or 747s).  Glad it's working there for you.  It might not work quite so well in an area with higher salt concentration, but then again in the hands of a good operator.....

thanks for the advisement, wont go past the ABS shaft part so am well aware of the water issue, so am working on a way to water repell the control box for the summer, so any potential water wont hurt the unit . and also as i have herd there is a learning curve , one i hope to master over time..........

As a follow up, I have been using a Tesoro EuroSabre II with a 12"x10" DD coil by S.E.F. Great and deep in the dry sand but too unstable in the wet. I could not ground balance correctly. It was usable, but I am going to try out some other (Viking 5 being the next:). The Silver did not make it to the beach, I have changed it for the EuroSabre II as I got a great deal on it. The Silver is a nice detector and I will buy another one when the funds allow

A small update:) The Viking 5 is next to useles where mineralized sand is (as on my test beaches). The depth is reduced to just a few inches. However I liked the tone response - non-motion mode with threshold. Silence means iron and one could hear even slight repeatable changes in threshold. Which of modern detectors has the same tone response? I'd love to have one like that - but only if the small change in threshold is caused by a coin at at least 10" and not at 3"

Yesterday I have tried my new second hand Silver uMax with the same 12"x10" DD coil. I have found some more old coins and a small silver baby ring where I thought I have picked all up with the EuroSabre. Either the sand has moved a little or I was fooled by the 3 tone audio ID. I dug nothing with a hint of low tone (think a bottle cap:) and I think I may have missed even some fully non-ferrous coins. Some of the coins had a much cleaner response in All metal mode. I think either the coins were not laying flat and/or the mineralized sand reduces the depth in discrimination mode. That was in dry sand.

In the wet sand zone I found two coins and a few aluminium pieces. All relatively shallow, as those were the only signals strong enough to distinguish from the falsing. The falsing can be reduced by swinging in parallel with the water line (you know that already:), but it took too much effort and I had very little time left for the wet sand yesterday. I assume that in the water it could be ok, as it is the wetness/saltiness change that produces falsing. Sofar, the most successful detector in the wet close to the water has been a C-Scope CS1MX in its threshold based discrimination mode - a gold ring at 5" and a silver bracelet at 4" as quite clear signals. I will try the 9"x8" concentric on the Silver to see if I can find some more stuff in the wet sand.

I would be afraid to take my Silver into the water, so I will hopefully soon test a cheap waterproof wanna be Fisher 1280 knock off TL-6003 I got cheaply. If it leaks and gets destroyed, I do not care much. The next step would be a PI machine (a DIY soon-to-be-finished Whites Surfmaster PI), but that will be another topic...
