Does Garrett Sea Hunter Mark 2 really eliminate pulltabs...............

[Ivan]

.......................yet still pick up gold rings????????? I think this is a bold claim...but can anyone tell me how true or accurate it is? Thanks.

 

[8720roger]

easy question to answer NO.

 

[Ivan]

so that means Garrett is a liar.............so sad.

I suggest you reconsider your statement, ask someone to try the discrimination circuit on different pulltabs and gold rings. You may find that it will still find gold rings of different conductivity while eliminating pulltabs. Check on youtube for videos of this test

They don't say it will eliminate all pull tabs and get all gold rings.

Any machine can eliminate pull tabs and get SOME gold rings. All depends on the ring.

Hi guys
I own a sea hunter mk2
A simple answer to your question is yes it can
But as said before. If you reject pulltabs. You wont find all sized gold rings and further more.
Your detection depth will suffer.

Loses too much depth, only use standard mode. Rings that come in like zinc will hit, the majority won't, period! Wow, that sounded like obama....

Wouldn't it just be a matter of the time constant of each target?

If you dial the discrimination circuit, which is a sampling delay, so that the sampling occurs after the eddies die off on the pull-tab then the pull-tab will not be detected. Every target that has a time constant shorter than the pull-tab will not be detected.

Since thin rings, light jewelry, gold chains, and other weak conductors aren't going to have time constants longer than a pull-tab - no detection. Thicker rings would have eddy currents that exceed the pull-tab's eddies and would be detected.

Iron would be temporarily magnetized by the field which would enhance the eddy field - most all ferromagnetic targets will then be detected.

Since pulltabs come in many shapes and sizes, and sometimes they are folded in half, missing the beavertail, and all of that...I dont think a fellow would want to disc them out at all, especially hunting sand and water where gold/plat has a good opportunity to be lost.

I cant imagine how this would be electronically capable for a machine to do and still hit a gold/plat ring of the same signature?
One could make the arguement that by discing out tabs, you will STILL find gold rings that are outside those mid weight ring signatures, but c'mon, how many tabs does a guy dig in a day of waterhunting? Even if that number were 100 which I doubt, unless you were hunting underneath a popular dock area, then you would also have lead sinkers to contend with too...

You may want to hunt chains, chase those foil and scratchy signals if you really want to go nuts! Then the nice crisp sound of a pulltab is a welcome relief!

Remember the #1 beach hunting rule is........ Dig all good repeatable sounding Targets above iron & The #2 Rule is to fill in your holes.

I took my CTX and ran 50 round & square pull tabs under the coil. Conductivity readings were from 16 - 22 hitting all numbers in between. I can tell you many gold rings fall in this range. Bottom line, Rob in Long Beach is correct, If it repeats, dig it out.

Regarding Garrett's claim of discriminating out pull tabs while hearing gold rings, though technically correct, may be misunderstood by newcomers.

You'll have to dig everything. I hate do that too but
if thats where the gold is...
