I bought a Sand Shark about 6 months ago and I was under the empression that this was going to be the "Beat all end all" machine for the beach...
I like it and have walked and walked with it... (well balanced, light weight)
I have been hunting for more than 30 years and can find my way around metel detectors no
problem, but there are some things with this that don't seem right and I want the opinion
of other "Sand Shark" users on this forum.
For one thing I was under the empression that these Pulse Induction machines went really deep.
I am using an 8 inch coil and after many different settings I settled on "Vol. all the way up, with the Threshold to where I could not hear it", so when I walk over something the threshould go's up and I can hear deeper targets.
But I have not seen much in the way of deep targets and most all coins have come in the
6 -8 inch range. Dimes on an air test are not much more than 6 inches, quarters are a bit better, but although I dug a fair amount of coins, non of them seemed very deep all all.
Almost all could be gotten with my hand. That said, I have dug a few nails pretty deep, and beer bottle caps can be dug rather deep, but these are bigger than coins...
Another problem I seem to be having is "Radio or electronic interferance"
Sometimes the threshold is silent as I walk the beach, but much more often than not
I can hear a constant "thrumming" sound in the back ground, sometimes real weak and sometimes real strong and there does not seem to be any rationality or consistancy to this noise, as I can hear it low on the beach (low wet sand area) and high on the beach (Dry sand area) I can walk out of it, one minute and the next
walk back in.... you can't tune the machine to block it, there is no sensativity switch.
Even turning the threshold down all the way does not block out this background noise, and many times with this chatter, it sounds like I am going over a target only to find no consistance to the noise and realize it's the interferance instead of a target.
Any one else experiance this with the Sand Shark ? And do I need to return it Tesoro
for them to do a "tune up" on my machine?
I bought it used, and it seems to work ok, just not as much depth as the people here
indicate a Pulse Induction machine should have.
Thanks
