Sovereign AM/DISC

G'day to all,

Well I'm back into my second Sovereign (GT) and have been very happy with the performance.
I'm 99% beach hunter so I'm always chasing the maximum depth.

My question may have been covered before but for those of you who hunt in DISC, do you find that good targets which are beyond an accurate tone ID (because they are deep) will null, followed by the "iron" buzz?

I have buried coins/rings at their maximum detectability....sort of the threshold of a "diggable" tone and a null. I am getting plenty of nulls. Bury the same target an inch shallower and then no problems with a good tone.

One of my buried test targets is at a measured 11" - 12" - 13" and 14".
The "Amped" Sovereign can now hit this at 14". Turn the Amp off and the target can now be hit at only 11".....so very easy to test with the press of a button on the Amp control box. A 3" improvement is very impressive in my books.

Also, I have just received an tested Shaun's Sovereign Amplifier and it brought a smile to my face.
At last, a product that doesn't just make target hits louder like all those regular audio boosters. I am confident in saying that for coin/ring sized objects, I was achieving approx 3" further "reach" (signal penetration) into the ground.

Okay, thanks for reading and any replies on the nulling in DISC will be much appreciated.

Regards,
Tony.:ausflag:
 
Hey Tony,

I agree with you on the deep good targets gving a null response, have seen it a few times.

question on amping the sov, while the depth increase is a good thing you gotta be careful where you use it as its gotta be amping everything in the ground, increasing masking and other issues as well? With sens to high false signals increase from just the ground, so how do you get around that with the amped sov?

Neil,

I only plan to use it on the beach and the beaches down here are low on iron targets.

I did a quick test with it today and ran everything at full sensitivity.......I didn't get any more falsing with the AMP than without it so I'm confident that there are only pro's and no cons with using it.
Because the AMP can be turned on and off with the press of a button, it is very easy to cross reference targets between the stock and "Amped" Sovereign.

The first positive is the deep coin.....the target nulled without the AMP, however, with the AMP on, I then got the good tone.

People must be passing up "iron" targets at the edge of detection, when some of these must be good targets.

Regards,
Tony.
 
I apologize if this was mentioned before but how much are the amps and where can I look at them online?
Thanks
 
Hi Tony,

If you have low iron that may be true but I have found that the amp does not like the salt water, at least up here in the northeast that is. I would be very interested to hear your results on your southern beach. I have been using Shauns amp for over a year now and the depth you get will surprise you. In wet sand it is an absolute killer as I have dug coins and rings at great depths. Work in all metal for best depth.
 
I had the same question, then I noticed ebay mentioned, so I just did a search on ebay and found the info....Ray

Thanks Bob,

I'll do some extensive tests tomorrow.

My "Southern" beaches are very similar to Florida beaches...very little mineralisation to speak of...naturally low in iron junk.

I mostly hunt up to the high tide mark and then down to the waters edge at low tide.

So far, there is only positives for the AMP.

Thanks for the AM tip....it does punch deeper.

Regards,
Tony.
 
Tony, wouldnt a PI type detector like the White's Surf Master Dual Field give you greater depth than the Sovereign?

I've tried Ebay,must be sold out.I also tried emailing Shaun but haven't had a response.Where else can I find one??

Willee,

I will probably get plenty of disagreement on this but here goes anyway...

My SOV GT with Amp and SEF coil will go deeper by about 2" than either of my PI detectors...... Minelab SD2200v2 or Goldquest SS.

There is simply no depth advantage on clean, white beaches in dry, damp or wet sand.......emphasizing also that there is no black sand to speak of.

I have tested and tested and the same results keep coming up...

For those that disagree then beach conditions must come into the equation somewhere.

Tony.

Sand Scoop,

Hang in there...I'm sure Shaun will get back to you soon.

I'm pretty sure that he only has 1 or 2 made at any one time....when one sells on ebay then he'll probably knock up another.

He only sells on ebay that I'm aware of.

iv had amp's in the past and they only increase the sound that is already there,like a volume boost.as far as sinsitivity,i cant run my Sovereign or Excal over 1/2 way on our beach's now so i dont think i need to amp that.but if they work in your case,thats great.the FCC controlls how much power a metal detector can put out so without being able to increase that i dont know how it would work here.you can make your own in-line amp,but the sound has to be there in order to amp it louder.

Bling,
My Amplifier is not a volume boost device. It amplifies the signal that the detector normally send to the coil to a higher voltage to produce a larger magnetic field around the coil. If anyone is interested in doing some research there are three standards that apply to metal detectors EN50081-1, EN50082-2, and Nilec Standard-0602.02-FCC. These standards do not limit the power to the coil they set limits on the allowable Radio Frequency energy emitted from the device. These usually point back to an Emissions standard EN55022 which looks at Radiated emmissions from 30Mhz to 1Ghz. One thing to note is that metal detectors coils are designed with a shield around the coils to limit the RF energy emmitted by the coil. Detectors do not use the RF energy to detect object, they use the magnetic feild which is not affected by the shield. Also, the coil drive signal of most detectors is under 100Khz which is very unlikely to create any interference in the 30Mhz to 1Ghz range.

I've had boosters, enhancers, etc and yes, all they did was make everything louder (targets and ground noise)...... but the Sovereign amplifier puts a stronger transmit signal into the ground.

It does not cause problems even with high sensitivity settings on the detector....again for my local conditions.

I have run the GT with SENS at 9 o'clock and the Amplifier fully maxed......smooth as you like.

I am 99% beach hunter in winter and this piece of gear gets me an extra 15% o 20% depth......:clapping:

Tony.
 
Not much I can say that hasn't been said already. The Sovereign is the greatest detector I have ever owned after using Whites and other Minelabs.
It is my primary land hunting machine and has yielded some great finds.

this all sounds good..this would be a great improvement to add that much depth! like going from a VLF to a PI.

I just wanted to update (correct) a post that I made a few months ago regarding the Sov GT amp and 15" x 12" SEF coil.
The great results that I was referring to related to using the stock 10" Tornado coil...apologies as I cut and pasted from one of my word docs on my computer.

The SEF coil was not happy when used in conjunction with the Amp. The audio falsed continually even at the lowest amp power settings.

The amp worked perfectly with the stock coil at all power settings.

The SEF coil by itself was great but ultimately had to go because it wouldn't work with the amp.

The AMP will never leave my Sovereign GT.

Again, I wanted to stress that my local beaches are free of mineralisation and EMI is also minimal where I hunt.
