Before buy a deep seeker PI or two box, look this test results

Hi People

I found this link about a test conducted for A&S company. Here I surprised the incredible depth that many MD two boxes can goes and another don't, included PI of $3,000.00. The Eagle Eye made a good job at 20' if you compare it with Pulse Star II pro.

Look the link

good info... thanks

From the link it appears as though A & S is trying to sell their 'Pulse 2000' over the Pulse Star 2 Pro.

I have the 'Pulse Star 2' and the depth is much greater than what is listed for the 'Pulse Star 2 Pro.' So unless Pulse Star made an inferior sequel, guess who gets the purchase if you accept their stats at face value? Also (for comparing PI to the other technologies) what they don't tell you is that for nonferrous metals, PI multiplies the depth greatly over most competing systems.

I agree with you and I had my personal question about that test.

Yes, I question all that too.  I have a Pulse 2000 and it goes much farther than they say.  It will go 7'-8' on a beer can in air, and farther in salt water or soil.  It will pick up a car or van at 25' +.  It will pick up a metal bucket at 10' in air.   That is with a 3' by 5' coil.  My Whites Surfmaster PI Pro will pick up large items(iron anchor with chain, aluminum chair, metal bucket, wire crab trap) at about 5' under sand.  Aluminum beer cans at 2 1/2'- 3' in sand - unfortunatly.  And it only has a 9.5" coil.

What 2 box detectors are good, and which are very bad?

In reality all two box detectors are good, all work well if you know how to use it and were use it and what are you looking for. In general are good deepers when you use it to find something big ( ej. 30x30 box and more, bigs cans etc ). Personaly I use it when I am working in areas rich in little trash were a pulse induction will be creazy or a VLF with high discrimination down its power of penetration. It is true some two box are hard to get a good null point like gemini III, this in special is no good in mineralized areas because has not a ground balance, but another are all automatic like garret, anothers have the ground balance etc. You must know what are you going to do with your two box.

Need a 2 box for treasure down 2 - 5 feet.

I would choose : TF 900 from discovery, withes 800 and garret with hound coils, this are easy to use and finding big targets ( 30x30 cms and bigs ) will be good for the work. Remember limitations this devices in your searching. Good hunting.

is TF 900 discovery the best?

The tf 900 and whites 800 are same thing, maybe the 800 has not now the cave selector, oldest yes. I have 900 and garret CX with hound coils they work great, 900 less havy. I have probed both in an unknow target, and they gave a good response, I finded the target 1.30 cm deep a big cap of steel 30 cm in diameter, very rusted.The manual ground balance is good because you are sure when you use it.In my country the 900 is very comun betwen treasure hunters. Good luck.

The good thing about the Garrett Master hunter cx plus is that with the 4". 7x10" and the larder coil plus bloodhound it makes for a very verstile unit.

Ihave the Garrett MasterCX with the Treasure Hound 2 box.   It is useful as a reg MD with out the Treasure Hound coil and then changes over in 2 minutes to use the Treasure Hound setup.    BUT,   I have sent mine back to Garrett twice, I had them replace the unit the first time, and the 2nd time they said they could not find a problem, that the unit worked fine!  BUT
It "goes out of Tune" very easy.
 
 You have to walk around carefully and not bump a bush or branch, and EVEN THEN sometimes mine starts giving a Signal Sound where there is NONE,  So I have to shut it off and turn it back on now and then.    
  I have a gallon can buried, standing upright, the top is 4 feet down, It will NOT detect it, its been buried 2 years.

 I just went out and checked it again.  This is the wetest Dec. in my area since 1853.  Still It will not detect that gallon can at 4 feet, even bending over holding it close to the ground.   You are to walk with it holding it with your arm in a natural position, so that puts the coil about 2 feet off the ground, at your knees.
 THAT REPORT AT THE 1ST OF THIS THREAD  SAID 5 TO 7 FEET FOR A GALLON CAN.  NO Way!   a gallon can air tested detection is about 30 inches for me.       

Yes, I have that  same problem with garret cx.When you walk must do slowly, because this is the better way to stay stable. Is true in ocations this device sounds where there is nothing in another you loss the base sound, I think this is more frecuent in urban areas, maybe anothers in this forum have something to say about this. I think the manual mode in tf 900 is most reliable. Maybe to this are good arguments to use the pulse induction detectors by some treasure hunters.Good hunting.

I remember the old BFO detectors.  Many great comments.

I seen a friend with the tf-900 testing his detector he got from A@S . has really good response to his target buried 4 feet in the ground target being a lid off a gallon paint can. He seems to be having some trouble keeping a steady threshold .just can't seem to get the ground balance correct . when you start walking with it the threshold changes from low to high sound. no matter how he adjust this  unit  it is like this detector is to sensitive  for walking .
and what he says is impossible to use cause you can't tell when you have a  target.
I have no clue other than what he is saying about this unit cause i am a begginer i do not have a detector yet. i like the way the tf-900 signal the target he had  just don't know about  why he can't walk with it. he has it set to instruction manual specs ,. just can't get a good fine tuning on it yet. maybe he'll figure out (his) problem. seems to be a pretty neat system that with practice a person could find some deep targets with.  but not  newby friendly. hope this might help someone considering this detector. if he gets the hang of this unit . i will update as to what the solution to the problem was he had. or if anyone wants him to do a particular test i will have him do it.

I posted a test I did with mine on the BRANDS : GARRETT detectors : section
 on this site. Any one interested in the GTI 2500 with the Treasure Hound should
 read it. If they want all the details of the test as to how I did it and why ( long )
 they can PM me and I will be glad to reply.

Which detector is the best for large treasures, and not for single coins?  We had a snow storm yesterday in Bridgeport, Connecticut.
