Mr. Andy Sabisch is a great metal detectorist and a great man. He after me reaching out sent my husband a free autographed book of his and sent us his business card. My husband has been wanting a Vanquish propack since the mentioning of it being made and Mr Andy offered my husband a great deal. See some people may not know he sells metal detectors. Mr Andy and his wife at Treasure Hunting outfitters have impeccable customer service and truly great deals and Mr Andy will work with me and He's letting me make payments. My husband is going to be so stoked for his birthday present. He is so ready to get back to metal detecting. See not many people know this but metal detecting saved my husbands life he was deeply and darkly depressed and suicidal about 10 years ago. He had his left leg amputated at six in a hunting accident his leg was blown off by a 12 gauge shotgun. At 24 10 years ago. He had his right hip replacement and they told him never work again. He's been on SSI since. Gets very little money I had to work 3 jobs to pick up slack. He felt worthless, useless and he was lonely because I worked kids were always at school and after school programs. He was very close to killing himself. He saw a metal detecting video. And they told Him he could do anything like that but he fell deeply a Passionately in love and was set on fire to get out and find history and discovered a new and free and whole other part of himself in metal detecting. His pinpointer recently broke and he needed one and i mentioned the vanquish to Andy and he ran a amazing deal by me guys I couldn't refuse at all. Period. 590.00 for a pulse dive and a Vanquish 540 propack..... That's major savings and he guys go to Andy for all your metal detecting needs. If he doesn't have it which most likely does he will make sure he gets it for you and as quickly as he possibly can. So go to Andy y'all. Great person. Sales@TreasureHuntingOutfitters.com
(734)230-1121. Oh promo going on 100.00 for pulse dive y'all. Crazy savings

Metal Detecting NWGA March 6, 2020: Here we take a look and listen to four popular detectors on common targets at the local park.
By Jeff McClendon
This is for those of you who may be wondering about purchasing an induction balance gold prospecting detector using mid to higher frequencies or just for the curious. I had a chance to do some comparison testing with the detectors below. Sorry, I did not have access to a Goldmonster 1000 or a Fisher Gold Bug 2. These are outdoor air tests in thick EMI and cold temperatures, 28F. I tried to set these up as close as possible, but coil size, DD or Concentric, and EMI susceptibility were out of my control. The detectors were placed on the ground with the coils perpendicular to the ground and each coil made contact with the ground at its heel. All detectors were ground balanced and noise cancelled or frequency shifted for the best possible EMI protection. The only detector that was really handling the EMI well was the 24K. I actually could have run it at maxed out settings, but to be fair I lowered them a bit to try to match the other detectors. Also included is one depth test for these detectors using each detector's coin/ jewelry mode that was used in the air test. This depth test is for a 5" deep US nickel (no snickering please since the Deus and ORX mineralization bars are 3/4 full or more in my dirt). This nickel has been buried for 2 years and currently the ground is frozen. So, these are tough conditions. From my experience with these detectors their air test results here (due to EMI) are very close to actual in the ground results within an inch or so depending on mineralization levels of course. Please notice the coil sizes used in the test before making a judgement.
I'm not trying to start an argument here. I like all of these detectors very much and they are all excellent gold prospecting detectors. This is for reference ONLY. Your results may vary a lot!!!!!!
so all you guys know your Detector? Or so you thought maybe or maybe so you thought?
So lots of you may be asking or have been asking or are curious about which Detector is better and probably assuming the 800 is way better and stronger than the 600. Or which is better for the beginner? The Minelab Equinox 600 or 800? What Detector is more powerful? Therefore producing more finds and at better quality? Or are they in a nutshell the exact same Detector besides A extra mode ( Gold ), and 20 and 40 khz are available to be single frequencies on the Equinox 800 and not the 600. Does The Equinox 600 have 20 and 40 khz in multi frequency? And the 800 has more adjustable tone pitches in more tone brackets and recovery speed is more adjustable and iron bias as well. But are as I said in a nutshell are the same exact animal. Truly deep, capable of all types of metal detecting adventures, fully submersible and the actually find amazing finds. Whatever you buy make sure it's a Minelab Equinox. They produce. Just don't go about it like I did and dying to set up most advanced settings and trying to copy someone's program. Let that metal detector talk to you and you'll create a bond with it and only tweak it when you feel the need to be able to comprehend it better. It's preset modes are incredible and this detector is truly worth every penny.... Thanks for listening guys

Which metal detectors have the most reliable target ID numbers?
Target ID is a function of depth - the deeper the target, the more difficult it is to get a clean target ID as the ground signal interferes. Other items directly adjacent to the desired target can also cause inaccurate numbers. The more conductive the item, the higher the resulting ID number, but also the larger the item the higher the number. Silver is more conductive than gold, so a gold item will give a lower number than the same size silver item. But a very large gold item can give a higher number than a small silver item, so numbers do not identify types of metal. Gold and aluminum read the same and vary in size so to dig one you dig the other. Only mass produced items like coins produce numbers that are more or less the same over the years but a zinc penny will read lower than a copper penny due to the change in composition.
In general iron or ferrous targets produce negative numbers or low numbers. Aluminum, gold, and US nickels produce mid-range numbers. And most other US coins produce high numbers. Other countries coins, like Canadian coins with ferrous content, can read all over the place.
The scale applied varies according to manufacturer so the number produced by each detector will vary according to the scale used. The 0-100 range for non-ferrous targets is most common but there are others. Minelab employs a dual number system on a 2D scale with thousands of possible numbers, but they are now normalizing the results produced to conform more closely to the linear scale used by other manufacturers.
White's Visual Discrimination Identification (VDI) Scale
Increasing ground mineralization has a huge effect on the ability to get a good target ID. Ground mineralization is nearly always from iron mineralization, and this tends to make weak targets, whether very small targets or very deep targets, misidentify. The target numbers get dragged lower, and many non-ferrous targets will eventually be identified as iron if buried deep enough. Small non-ferrous readings and iron readings actually overlap. That is why any discrimination at all is particularly risky for gold nugget hunters.
If you want target ID numbers to settle down, lower sensitivity and practice consistent coil control. The target number will often vary depending on how well the target is centered and how fast the coil moves.
Higher sensitivity settings lead to jumpier numbers as the detectors become less stable at higher levels. The interference from the ground signal increases and interference from outside electrical sources also increases, leading to less stable numbers.
Higher frequency detectors are inherently more sensitive and are jumpier. So lean lower frequency for more solid results. Multi frequency detectors act like low frequency detectors and tend to have more solid target numbers due to the ability to analyze a target with different frequencies.
Another issue is the number of target categories, or ID segments, or VDIs, or notches, or bins (all names for the same thing) that a detector offers.
For instance here are the number of possible target id categories or segments each detector below offers:
Fisher CZ-3D = 7
Garrett Ace 250 = 12
Minelab X-Terra 305 = 12
Minelab X-Terra 505 = 19
Minelab X-Terra 705 = 28
Minelab Equinox = 50
Fisher F75 (and many other models) = 99
White's MXT (and many other models) = 190
Minelab CTX 3030 = 1750
Fewer target categories means more possible items get lumped together under a single reading, but that the reading is more stable. Many detectors will tell you the difference between a dime and a quarter. The Fisher CZ assumes you want to dig both so puts them under one segment along with most other coins.
People who use detectors with many target numbers usually just watch the numbers jump around and mentally average the results. Some high end detectors can actually do this averaging for you! But I think there is something to be said for owning a detector that simplifies things and offers less possible numbers to start with. The old Fisher CZ method still appeals to me, especially for coin detecting. So do detectors like the Garrett Ace 250 or Minelab X-Terra 505 for the same reason.
The problem is that as people strive to dig deeper targets or smaller targets the numbers will always get less reliable. But if you want to have a quiet performing metal detecting with solid, reliable target numbers look more for coin type detectors running at lower frequencies under 10 kHz or at multiple frequencies and possibly consider getting a detector with fewer possible target segments. And with any detector no matter what just back that sensitivity setting off and you will get more reliable target numbers.

Detectors often use tones to identify targets and often use far fewer tones than indicated by the possible visual target id numbers. The X-Terra 705 for instance can use 28 tones, one for each segment. However, most people find this too busy, and so simple tone schemes of two, three, or four tones may be selected. I think it is instructive that many people often end up ignoring screen readings and hunting by ear, using just a few tones. This ends up just being an ultra basic target id system much like the simpler units offer. Reality is that most people do not need or care about huge numbers of target numbers. For many just three ranges suffice, low tone for iron, mid tone for most gold items, and high tone for most US coins. The meter could do the same thing, but for marketing purposes more is better and so we get sold on detectors with hundreds of possible target ID numbers. Perhaps this is a digital representation of an old analog meter with its nearly infinite range of response but the reality is we do not need that level of differentiation to make a simple dig or no dig decision.
Finally, a picture often says it all. Below we have a shot of the White's M6 meter. I like it because the decal below illustrates a lot. You see the possible numerical range of -95 to 95 laid out in the middle. Over it is the simplified iron/gold/silver range. Note the slants where they overlap to indicate the readings really do overlap. Then you get the probable target icons. -95 is noted as "hot rock" because many do read there.
The M6 can generate 7 tones depending on the target category. I have added red lines to the image to show where these tones sit in relation to the scale. It breaks down as follows:
-95 = 57 Hz (Very Low) Hot Rock
-94 to -6 = 128 Hz (Low) Iron Junk
-5 to 7 = 145 Hz (Med Low) Gold Earrings, Chains - Foil
8 to 26 = 182 Hz (Medium) Women's Gold Rings/Nickel - Small Pull Tabs
27 to 49 = 259 Hz (Med Hi) Men's Gold Rings - Large Pull Tabs
50 to 70 = 411 Hz (High) Zinc Penny/Indian Head Penny - Screw Caps
71 to 95 = 900 Hz (Very High) Copper Penny/Dime/Quarter/Dollar
Note that the screen reading of +14 is noted as being a nickel or ring but it can also be the "beaver tail" part of an aluminum pull tab or the aluminum ring that holds an eraser on a pencil, among other things.
The best book ever written on the subject of discrimination is "Taking A Closer Look At Metal Detector Discrimination" by Robert C. Brockett. It is out of print but if you find a copy grab it, assuming the topic interests you.
Always remember - when in doubt, dig it out! Your eyes are the best target ID method available.
The passing of a friend unfortunately has led to me taking ownership of a modified Tdi Pro. My machine is mounted on an Anderson shaft and is factory spec. My old mate had his machine modified to smooth out the threshold and to add some sensitivity. The specifics related to the modifications are not known by me, other than that they were conducted by 'Luke'..Oz Digger.. This happened some time ago. So the modified machine is probably not a keeper, I don't want two Tdi Pro machines.. The opportunity to do a comparison cannot and should not be ignored.
My intention is to focus on small gold performance, the threshold smoothness, the ability to use gain, basic performance and handling characteristics under different circumstances. The machines will use the same fully charged battery pack, same coil, same targets, same test location and conditions on the same day etc. Trying to minimise external variations. I'll start with the usual useless air test. Later I'll follow up with in ground testing on the actual goldfields in mineralized soil. Test coils will be with a small coil and a large coil. Targets will be gold only. The 1 grain ingot, the half gram gold coin, a half sovereign gold coin. Some real small sub gram nuggets to see how small we can go.. There is a process involved so I'll take my time and do it right. Any specific questions or suggestions, speak now or forever hold you peace.. I'm only doing this once. Once it sold it will be too late to revisit..
All the best.
