The Anfibio known as a deep machine using small coils has sorted out old silver in trash that has by all accounts been pounded for decades. I assume mainly by bigger coils, rarely need to swing the 11" stock coil. I am hopeful that is the case with the Legend coil size availibility.

Nokta sponsor a team of Americans and a few people from other countries to market their detectors by providing them free gear,  they're mostly active on Facebook I think.  I've not paid much attention as I'm not interested in marketing schemes like that. 

 

I am really out of my wheel house with metal detecting marketing it (XP approach in particular) defies logic, but Darnell Williams whom is/was a NOMAD really helped me to learn, understand and eventually open up the flexibility of the Anfibio via his youtube page. I believe he settled on the companies products long before he took an opportunity to become a NOMAD. Organic product.

As is often the case (even for professional journalistic works), the (thread) title doesn't tell the entire story.  Watch the video for details.

I'm stumped -- what/who is the 'Nomad' she refers to?  Surely not this....

https://www.noktadetectors.com/nomads-team/

If this were a machine with tone and volume control this could be addressed by changing the selected tone to a different frequency (this function is available on the two machines of interest), and then adjusting the volume level of that individual tone to best contrast with the emi tone (this function is unavailable on all machines mentioned here). 

We all know why Audio Response provides a useful benefit. When you turn it down to level 3 you are adjusting the audio dynamics. The deep target is not lost in the louder tones because it has a lower volume. Please correct me if that is wrong.

How many decibel levels are available for customization on the Equalizer? Three level choices: low, mid, high? If you want to obtain useful customization across the four available bands then you need at least four decibel level options for the user to be able to fully impart custom dynamics across output volume. You would prefer at least five levels to provide even more capable separation of the four bands to enhance the users control and obtain the sound quality benefit of custom dynamism.

Good deal. Many perceived the actual US release strategy as a marketing scheme if that is true then this will mark the end of an intentional bottlenecking of information.

Other lessons from bench and field:

 5 Tone can help sort out the mixed iron and non-ferrous groupings that 99 Tone wants more clarity on; with a single button toggle. A perfect one two punch for examining the mixed metals of trash.

5 Tone is a mode I have mostly neglected up until now, but it is deeper than 3 Tone and seems to have a faster recovery speed than 2 Tone. 5 Tone will get more exploration based not on the multi tone facility, but instead based on the practical ratio of recovery speed to depth in my moderate to challenging soils. If we were to get an update to the 2 Tone, this 5 Tone depth and recovery speed might be appropriate.

Another tried and true lesson from bench field is that overload signal can mask the potential response from adjacent targets. Though overloading only happens a small percentage of time overall, it does inhibit beneficial removal of iron/trash from a location in part because the pin-pointing function of the machine is disabled by the overload circuit. The Deus has taught me that this is the primary drawback for the Anfibio in iron and trash. Yes you can lift the coil, but that is not an ergonomic or competent solution in the field.

Not being familiar with Anfibio nomenclature, not sure how your Anfibio disc/notch settings compare to the Disc settings on Deus.  Deus full tones suffer from the fact that you have no iron volume feature if disc is used.  Just silence.  Can you elaborate on the disc settings and how they compare between Anfibio and Deus. If running FT with no disc on Deus not surprised by your junk recoveries on Deus.  Invoking disc/notch on Deus could result in a different outcome in that regard.

I am surprised that the button did not elicit a would dig signal on Deus.

Sure Chase, good question. Here are the full Deus settings: Disc -2.5 Full Tones Sens 89, Tx 2 ,Freq 12, Iron V 1, Reactivity 3, Silencer -1,  Audio Response 3/ Overload 1, no notching.

The Anfibio 0 Disc, Notch 1-3, and Notch Volume 2.

Once I took the cover off and could see the targets the button got spanked soundly. There was interference from a larger than average pull tab 1" away and small low conducting pendent 1" away that was affecting the tone, as well as other trash on the approaches, but I am 100% chalking that particular result up to my experience level with the Deus. This is not a comparison of the machines just a learning endeavor, and a narrower coil on the Deus would have performed better. 

That many unseen items in such a small space is tough to pick through. Uncovered and in plain sight you can wiggle more of the targets out. One Silver Quarter would have gone undetected by all machines even in plain site due to proximity to a nail, an elevated aluminum foil, and an elevated angled rusty bottle cap. A mid sized dense silver earing was wiggled out in some trash once the bench was uncovered, but good luck in that scenario buried in the field. 

Quick conclusions, and there will be more: I am not convinced at this point that 99 Tone is better than 2 Tone Pitch with custom Tone Volume on the Anfibio in mixed trash. I learned tone quality is everything inside a trashy (outside of normal/clean TID) target group, and that I need a lot more time on the Deus before she heads to the mountains with me to get her day in the old iron. It is still plenty cold up there.

If i can get out today it'll be the Anfibio 2 Tone with preferred break and tone volume settings leading the charge with this knowledge gained from the bench. I know where some analogous trash is located and it is calling to me.

I decided to go with dig/no dig, and omitted (would likely dig) for Test 2. I also notched TID 1-3 on Anfibio and reduced the volume from 5 down to 2 for that iron range.

In theory trash aside the take home for the Simplex would have been a Small Pendent, and the W Penny. The Deus would have pocketed a Nickle, a S Dime, the W Penny, and the Small Gold Jewelry. The Anfibio would have netted a Button, a C Dime, the W Penny and the Small Gold Jewelry.

Obviously these tests are for my learning purposes, and should not be considered as anything other than that. Next I will be go back and look at the TIDs to try to improve my decision making  and squeak out more dig-able signals from this composite matrix.

Here is the bench sheet.

On the initial target response from the cardinal directions and stopping with center of coil over center of bench: Simplex (S) Anfibio (A) Regular Deus (RD)

North- Pull Tab A: SARD, Thin Aluminum: SRD

South- Button A: SARD, W Penny ARD

East- C Penny: SARD, False: SRD, Pull Tab B: RD

West- Button A: SARD, Pull Tab B: SA, Screw Rivet: S, False RD

Scrutinizing the bench only 19 of 22 targets were located blind with audio only. Two S Quarters (each located with challenging adjacent targets) were not located.

Test 2 Dig/No Dig across the identified 19 targets.

Simplex would have dug 5 targets:

1. Summed Foil/Pendent

2. Summed Rivet/Screw

3. W Penny

4. Summed Pull Tab/Rivet/Screw

5. Thick Aluminum

Deus would have dug 9 targets

1. Foil

2. Nickle

3. S Dime

4. W Penny

5. Pull Tab

6. False

7. Summed Pull Tab/Screw/Rivet

8. Small Gold Jwlry

9. Thick Aluminum

Anfibio would have dug 7 targets

1. Button

2. Rivet/Screw

3. C Dime

4. W Penny

5. Gold Jwlry

6. Thick Alum

7. False

I am doing some experimental bench testing (Deus Fast FT X35 9”, Simplex Park 1 SP24, Anfibio 99 Tone KR24) with interesting results. Determinations are by ear only. The bench 12” diameterl, there are 22 individual common conductors (trash and treasure) spaced randomly at varying elevation and angles to the plane. Each detector was then used to confirm that each conductor could be distinguished where I can see the conductors and am using whatever swing speed, coil height and angle need to get a distinct signal. I covered the whole thing with a towel and rotate it hiding the signals and eliminating my memory  of orientation.

I use all 3 detectors as a team to single out and locate all of the covered targets and place a number for each target on the towel for each location of each conductor hidden below.

Test 1 is using a normal swing width and speed approaching from each cardinal direction to determine which conductor(s) dominate the audio and initiates a response to investigate further, a subjective measure indoors. Obviously investigating the target will reveal adjacent targets and potentially more desirable targets but the focus is on the primary signal(s). Audio only.

Test 2 is using each machine across each conductor and grading them in three categories: (1) would dig, (2) likely to dig, and (3) unlikely to dig. Audio only.

Due to weather these tests do not have the control that I need. If the outdoor tests show that the indoor tests are not fatally flawed, then experienced users are right about pitch and full tone programs performing better than multi tones, 99 Tone is not outperformed by the Simplex, and 99 Tone is competitive with the Deus. I will set it up with tighter control of variables at some point and try again. In the meantime, employing 99 Tone and continuing FT usage while learning the Deus are the obvious priorities.

Kac thanks for sharing the knowledge, you know more about the machine than I do. I have read most if not all of your posts here in the past so you have definitely helped this amateur along the way.

I saddled the KR 28 11"x 7" search coil onto the Anfibio this evening for a quick tour of some uneven/choppy ground in 3 Tone and rode her back in time again finding a neat relic, and another old coin. I like that coil but had not used it in a while. Now it is very efficient at describing trash, pull tabs, and bottle caps along with the desirable targets. 

I hear you on the Deep mode, I have used it with the smaller coils and found my best coin to date in a pounded park that way. 

Nokta in case you are listening, we are interested in an update for the Multi Kruzer and the Anfibio to include a more stable 2 Tone program.

The Regular Deus (RD) has found a neat relic, a silver ring, and some coins in limited time in locations previously unsearched by me using Sonar and Sifter concepts primarily. We are liking the Deep as well. The Deus tracking the Anfibio at Site 7 provided an advanced description of how trashy the site really is (a stand alone advantage), but RD 9" in only retrieving two coins also pointed out how well the Anfibio KR24 has performed at the site.

The Anfibio said damn straight, now take off those uncomfortable HP lets run a wide open pitch concept and attenuate the volume output of notched TID  0-25 in 99 Tone and track our compadre, RD. The applied concepts were obvious in the quick acuity with a minor adjustment to reduce swing speed. At that point even if no new desirable targets would have been found I could say that at least for me the shared wealth of knowledge about the Deus and practical time with the machine have been worthwhile, and then as if in agreement the Anfibio rustled up and netted two more old coins with the selected pitch audio in the setting sun at the pressured site.

I use notch audio on my MK in 4 tone as it doesn't have a 99 tone but still incredibly effective for coin shooting at campsites.

There is a post somewheres that shows my notch pattern I use using the Normal scale so you can swap frequencies and not shift the breaks.

I really like how easy it is on the MK to usefully cycle through various settings and options to check out questionable targets.

This may be changed with version update.  Soon maybe.

That would be a game changer for people with tinnitus or other hearing issues. Tone and notch volume controls should be standard on an elite machine.

I am hearing output volume levels across those variables that the Deus that some engineers in France decided for me that I should hear. We have talking heads decrying the fixed inflexibility of other machines while being intellectually dishonest in that vein about the D2.

I love the descriptive audio of the Deus but I do not love the inflexibility and particularly the limited use due to it increasing tinnitus. 

These output audio controls open up the Anfibio. Just a simple notch volume control even for a pitch program like 99 Tones allows me to hunt without issue.

I hope XP has been listening.

I feel fortunate that my first machine has notch volume and tone volume controls. Experience has taught me that some non controllable dynamic output machines can increase tinnitus in one of my ears over time. I can use them but with time limitations. Listener fatigue is another problem with machines that do not allow the user to control audio output volume levels. User controlled tonal and notch volume also provides useful practicality in discerning targets.

Scout Audio Program:

Anfibio KR24: 9.5 x 5 coil

Two Tone Mode (VCO Audio btw)

Discrimination: 0

Notch volume: 1 (Notching 1-21) (The floor volume)

Tone Break: 79 (you can adjust it if you do not want to break around clad dimes and pennies) that breakage is an alert signal in a useful area proceeding the silver range .

Tone 1 = volume: 2 (users tonal preference) or a Low tone

Tone 2 = volume: 5 (users tonal preference) or a High Tone

14 Khz

Gain: 79

This two tone program essentially becomes a 3 tone program with dynamic audio output.  Once a site has told me a little about herself, I may take notch volume to 0 and Tone 1 volume to 1 where I can still hear targets in the 22-79 range and investigate them further as needed. The advantage is obviously for silver where the volume weighted high tones can help scrutinize some iffy signals.

This is not just a silver picker program. It provides enough volume even on a windy day from the headphones to scrutinize signals in the attenuated iron and mid conductors, and it also does a good job of identifying rusty bottle caps.

A new (to me) site that is surely no virgin with this program kept the Deus in the truck and produced 5 wheats and a silver on a Friday evening hunt. Do not fret, the Deus and Simplex will eventually get opportunities to try and clean up after the Anfibio here.

No message

I was going to do some kind of comparison in the trash, I found a 65 dime (KR19 relatively deep in tree canopy trash area) with the Anfibio, and a 42 wheat with the Deus at the base of a tree, at different sites instead. You know.

I have learned that the Deus and the Anfibio are in the same general class across park and field with Deus exceeding in processing speed and voice, and Anfibio exceeding in coverage opportunity, coil selection, and audio output attenuation control across tone, VCO, and notch in useful integers.   

There are iron and trash limitations with the Anfibio, but even mid level users are able to pull desirable targets consistently at live sites wherever they may roam. There are absolutely site conditions that limit the Deus coverage here but as a clever tradeoff it is very confident in the iron.

Trailing the Deus behind the Anfibio at Site 6 provided an opportunity to further explore the benefits of Deus processing and vocals. The Anfibio seems to have done a good job of clearing out trash, and multiple silver from this trashiest site on my list. The Dues only picked a silver and a wheat, the Anfibio a subsequent wheat, and as if in a competition or something a quick silver bracelet just around the corner from there. I have no doubt that as I continue to learn the machines they will both continue to pull old coins. This site has a lot of subsurface trash and iron, along with conductive surface objects. The Anfibio overload signal here is normally due to large iron, a little different and less inhibiting than her overloading from sub surface flotillas of pull tabs and bottle caps in picnic areas and other similar conductivity scenarios. The iron at Site 6 that overloads the Anfibio is the same iron that the Deus just casually describes for you.

Starting off metal detecting in earnest with the Anfibio was a learning experience, the Deus has given me feedback on what I learned, and the most important lesson of all I think is that these two machines genuinely complement each other in this part of the world.

I wish I had started to work with the 99 Tones prior, looking forward to exploring some more with it. I went back tp the site with the 9" and was limited in access at the location due to tracking. As in well defined boot footprint trails in the crunchy grass. Wild. Before I left I dropped the notch value down to fit the playground targets, and found an old pendent with a race car and wreath wrap on it.

Next up a super (just below the surface) trashy area where I am going to grid with the Deus 9 side by side with the Anfibio KR19. I am a little biased the KR19 on the Anfibio has paid for the detector twice over, but the this is an overload inducing site for the Anfibio so it should be interesting.                                             

I am test driving a Deus I . I had been enjoying the Full Tone audio in a couple of different scenarios but It wound up on the Detector Unable to Participate (DUP) list over the weekend. So I broke out the Anfibio with the KR 19 sniper coil and hit up the sites that had been planned for the Deus 9” and decided to give  Anfibio 99 Tone a crack at them. I am glad I did. At my last site I applied notching and subsequent notch volume to make for a successful authentically dynamic coin program, easily dialed up on the fly.

At this site I was searching for coins in plenty of small iron and moderate to heavy trash with a tone volume of 4 and notch volume of 1. Discriminating 1-10, notching 11 to 65 and 97-99, using 5 khz everything else stock. It easily located coins, even with the small coil I reached down into 1969 twice. The 9” concentric is next batter up at this site, with this set up.

I have to admit prior to this I had not given 99 Tone a thorough opportunity to show me what it could do I have a new appreciation for the machines capabilities, and dynamic full tone audio is a great corner to occupy in my opinion.

"As far as stubble, cultivation furrows and high grass is concerned, that is what the Audio Response setting and VCO audio programs like the Relic mode and the Pitch audio setting are for in case you need to keep the coil well above the ground."

 

 

Audio Response on the D1 is a very good control to have I like 3 the most so far. I am an avid user of VCO on the Anfibio Multi.

As far as stubble it is native mixed grasses cut on property subject to regulation. I do get some ag stubble in other situations. This situation is more about working the spots on the property with the shorter grasses and bare dirt like they are ponds coves or bays land locked by the stubble so to speak. In most of the situations it is more like a puddle here and a puddle there. I drop the detector in there like I am dropping a worm on a nest, you know. Whether working edges in the tighter holes like this or along the edge of the larger openings, the Anfibio Multi is stout. It does not bounce off of the stubble, the D1 does so with surprising vigor. Like a pinball off of a bumper.  In other cases in these grasses the Anfibio Multi can also be operated closer to the ground when skimming grasses. In this semi arid and drought prone region the stubble weakens in the winter months offering more coverage area opportunities, at least for the Anfibio Multi.

Good to see that the Anfibio Multi is not on that list.

The ruggedness (it is a creeker, and that is a sturdy compliment), the coil options especially those smaller than stock, the top shelf audio options, and the reliably good performance in most situations make it a significantly better than average all around tool in its price range that would be difficult to replace. As good as the Deus, and the Nox are, they are not creekers in my opinion; too dainty.

Some software updates might make the Anfibio Multi even better in the future.

I have apologized to Calabash and to Steve for my antics and personal attacks here. Steve has allowed me to return. I agree that i did a bad job of organizing my thoughts on this thread. Thank you to Steve for allowing me back Happy New Year!

Lets move forward. 

This has been so far the toastiest and one of the driest  if not the driest to this point winter up here in the Panhandle in my life. 

On the Anfibio even in VCO modes such as 2 Tone and Deep you can adjust the volume level for each tone independently. Put your tone break(s) wherever you want, then adjust each frequency to your liking, and then use volume to add weight to whichever tone(s) you want to be dominant and to what degree. You can see where this is useful for all multi tone modes. I reckon Gary B. would be able to conjure up some program platforms with those knobs.

But as some have suggested XP may not need any audio suggestions as it seems their machines work just fine

Just got in.

Skimming, I see there are quite a few solid comments that I will go back and fully read in the A.M.

Day 2 with the XPD1:

Gary Blackwell is a premium asset to XP. Watching his videos set me up for operational success first rattle out of the box. Yesterday I banged out a silver the Anfibio had overlooked in a high trash area. Today his Sonar program in the iron delivered a day maker button with local history. Imagine what Gary could do with independent tone volume controls. ; )

I am surprised by how well the audio communicates to the user. There is some high end intuitive design incorporated in this audio circuitry, and obviously that is not an easy thing to pull off. 

The Deus was restricted by vegetation that the Anfibio can get through with less effort, but the light weight of the Deus provided me better total area coverage.  

Give me a rugged XPD2 with tone volume control and then watch out because all bets would be off. If they are not already so.
