Barely Audible to Silent Threshold

[clearwater]

gulf hunter, ive seen in numerous postings a recommendation to run sensitivity at 11or 12on the excalibur,the manufacturer suggests auto while in the water,,they suggest sens is reduced as you advance out of auto ,help me out,thanks

All you have to do is air test the Excal. to find out and experience it for your self. Take a piece of gold place the unit in auto sens. and then wave it in front of the coil. Now place the sens. to 12 oclock. Wave is again and see how much farther you can go out from the coil. Now get the max distance as you can with the sens. at 8 oclock waving your gold ring, then switch it to auto and notice how you can't hear the object at the distance you had it at at 8 oclock.

Ok,

that makes good horse sense!

No auto.

Cheers Lou.

I got 3 more rings today with the Gulf Hunter settings. A junker, and 925 silver wedding band ( first one of those) and a 14K gold wedding band, and we are pretty much sanded in except for a small deeper trough area I found. I am still trying to wrap my head around this threshold dilemma, but I am going to ride this horse for a while longer.

Its great you had some nice finds but it doesnt mean anything concerning the threshold unless you tested it both ways on those targets and found one way worked and another didnt.

both settings will find rings/coins etc, but only one will allow you to hear the deepest targets a sov/excal can find in disc. Im not referring to that annoying buzz that comes back after youve gone over iron or any disced out target, but a change in pitch in the threshold only.

if your sanded in and want some deep ones try running in all metal, and on the faintest small targets switch over to disc and see if the detector nulls out, if not, dig away.......all metal is the deeper seeking mode.

have tried that once or twice, but not for very long. Think I may try it tomorrow as the sand moved again, as in sanded in, much less clad and one junker ring today- silver plated.
