I have a site that's another example of EMI reduction by moving from 5kHz to 4kHz.

Electric dog fence around the perimeter of a yard.

Neither Impact or Equinox can run at 5kHz.  Completely unusable.  Regardless of frequency shift, noise cancel, or coil size.

I can run the Equinox at 4 though if I noise cancel.

...Some things have got lost it seems along the way. Like true unfiltered all metal detection, something the T2 and F75 excel at. The new digital models process and filter everything by the nature of how they work. The result is not the same. 

Thanks for bringing this up Steve.  I enjoy my Equinox and Atrex but it's one reason I keep my Nokta Impact.

4 different REAL all-metal modes, both motion and non-motion.

Phrunt,

I also use the Atrex EMI screen before firing up my Equinox 600 or the Impact and indeed watch for a few min before deciding on frequency choice on those machines.

Correct Dig.

Lowest = 4.4kHz

Highest = 18.4kHz

Dig,

Yes.  It looks like a graphic equalizer.  Whatever your current selection is, it shows that in the middle and you can see lower and higher to the left and right.  Then, you can scroll through them all using the + and - keys to move left and right.

Here's a video Tony did...https://www.youtube.com/watch?v=UtgvjZyuGYM&ab_channel=tcDetects

Yes SMF is almost always noisier than single, but I like being able to shift the SMF while staying in the mode I want when possible.

If EMI is too much on all SMF modes then I go single.

This shows interference even when you can't audibly hear it.

Ok, so a little change. The AT Max had 3x coils (regular, sniper and large one), as well as 3x headphones (including Amphibian Grey Ghost. Still a better buy to go for the Legend base kit with no extras?

I'd go with the Legend over the AT Max without question.

EMI aside, I always choose SMF because I'm never just hunting for one specific type of target.

Same example house in my last post, I can run the Atrex in M2, M3, but mainly M4 next to that house.  The other SMF modes have noise.

Much better ID at depth and significantly less falsing than single freqs.

(Post for another day would be me grousing that all these new detectors can't run concentric coils.  I have a 5" cc sniper for the Rutus Atrex and a 7" cc for my Nokta Impact.  They can also be a nice advantage in certain situations.)

Auto noise cancel wouldn't let you know whether you should be using one of 10 SMF modes, or whether a single freq. would be best.  It would simply freq shift after you made your choice.

ie.

When detecting next to an old home that has beat up aerial electrical service, I can scroll through EMI preview on all the single freqs as well as the SMF modes, then make the best choice at that moment.

There's also silent EMI that shows up.  Most guys ignore it but it has more of a negative impact than they realize. 

Using my Equinox at this location I can only run it at 15kHz with the sensitivity turned waaaay down.  It's neutered.

The Atrex detector is at another level when dealing with EMI.

I just wish it was waterproof and that the color screen didn't wash out so badly in direct sunlight.

Rutus Altrex has a screen that shows you what freq has the most EMI interference.

The Rutus Atrex EMI preview screen is a game changer.

I use it for both the single frequencies (71 of them) as well as which of the 10 different SMF modes to use.

AFAIK, the kruzer was a refined, waterproofed Impact platform, and the Anfibio was a Kruzer with more features. There was always overlap in the two companies' machines, I'm pretty sure the racer platform was based on the Fors Core, just put in a more typical/ergonomic package. 

 

Kruzer was a souped up Racer 2 and the Anfibio was a souped up Impact if I remember correctly.

I like the question/thought process Digalicious. 

His statement doesn't make sense to me.  With my limited knowledge it seems like driving in the fog with your high beams on.

There are different types of mineralization though....I guess that could be a factor.

Whether mineralized or not, if he can properly ground balance (or even go a pinch negative) to effectively mitigate the dirt, then adjust sensitivity, frequency, and/or coil size to mitigate EMI he should be able to maximize depth.

I had a permission with an electric dog fence.  The only machine I could run within 10ft of it was my Impact, running at 20kHz (and adjusting the freq offset about every 20ft), using the tiny 5" coil.  I was able to pull a couple largies, an 1881 silver candian qtr, and the belt plate in my avatar.

Most sites aren't that demanding but environmental issues cause SOME need to tweak.  What he's saying defies logic.

Simplex won't do great on salt beaches, or while nugget hunting.

I'd agree with Matt and have you look at the Legend.

Looking forward to it.

Alaska is a dream trip of mine.

I hope that someone can help me out with a problem that I now have.

My hearing is getting bad due to constant ringing in the ears and I am unable to hear all the tones.

This has happened due to using a mini-sub for work all the time and the doctor tells me that it will only get worse.

I have my grandfathers 800 that I have been using and am having problems hearing the tones that I know was there before.

Soon I have to start taking a break from work or I will lose my hearing all together and I thought I would get back out there with the detector.

Does anyone have any suggestions that I can do to be able to hear the tones, or do I just need to use the ID's on the display.

I can no longer hear low tones or real short tones and that is what bothers me, and I don't like wearing headphones because I want to be able to hear what is around me.

If anyone has any suggestions I would appreciate hearing from you.

Thank you, Caleb

I have a similar, yet opposite problem.  I can hear low tones but not high tones.

Adjust the tones and slide the scale up on your machine so you can hear all of the bins.

I use DetectorPro Black Widow headphones that were designed for folks with hearing issues.  They are fantastic and worth the money.

I still like my Equinox too.

These new machines didn't make it obsolete, nor did the Equinox make my other VLF detectors obsolete when it arrived.

So many fanboys were wrong about that.

Rutus Atrex is now my main.  Still pretty new with it.

Minelab Equinox and Nokta Impact are the backups.

A Manticore has the head of a man, body of a lion, and the tail of a scorpion.

My bet is they chose this name because the detector blends3 technologies.

Multi IQ, FBS, and another tech.  Maybe BBS.

I've had a similar model from the same company for about 4yrs. 

I've got the Nisaku Miyamatou with a wooden handle.  It's a fantastic product.

I like it more then a lesche.

My new Rutus Atrex is on the way from the UK.

I ordered the white 11" DD and the 5" concentric coils.

Just need to find a good set of aptx LL bluetooth headphones to use with it. 

Nokta (before the Makro merger) without a doubt.

The Makro Racer 2 with the 4.5"x5" coil was great in trash, but the Nokta Impact running at 20kHz with the 7.5"x4" coil is a laser in the thickest junk.

Thanks EL NINO77.  I'm looking now for an available one at a good price.

Does anyone here have 1st hand information or experience with the Rutus Atrex?  I watched some videos on them.

No resellers in the US but there are in UK.

Can you expand on the inline part? You mean you attach the pinpointer to the device? 

 

Yes.

Essentially the pin pointer becomes a tiny coil and uses the detector settings.

It's totally doable, and IMHO it would be a HUGE hit (not to mention an awesome competitive differentiator) 👍

Dilek,

If NM is able to come out with an inline pin pointer that uses the discrimination settings setup in the control until of the detector I will immediately buy 2 complete detector+pin pointer setups, as will many others.  

Sunray used to produce that type of unit and was popular with Explorers and ETracs.

I was swinging fast in high grass and smacked a small hidden stump.

I was more than a year out of warranty and it was my fault so I didn't contact Nokta.

Nokta have indicated the Legend supports Concentric coils.

I still have an Impact and almost exclusively use the 7" concentric and their 7.5"x4" little football coils.  I broke the stock coil and replaced it with a 13" Mars Discovery.

The concentric is my general use coil for it.
