My VLF detectors are rapidly sorting themselves out and I am satisfied I am doing about as good in that regard as can be done. There really is only one area of metal detecting left that is bugging me.
The Garrett Infinium was the first waterproof ground balancing PI and not a bad first effort. White's TDI might have improved on it but White's never did a waterproof TDI. Surprisingly, Minelab has never done what I would consider to be a true waterproof saltwater beach hunting PI. The SDC 2300 really is a prospecting detector first and second. I finally ended up with the Garrett ATX, which currently sets the bar for a waterproof ground balancing beach and water detector.
Yet the ATX housing was designed more for military use than beach detecting. The coils are overly expensive due to an integrated rod design. Worse, the detector weighs in at 6.9 lbs and cannot be hip or chest mounted.
In a sign of faith I am going to sell my ATX and wait on whatever First Texas has in the works. As Rick Kempf posted here previously, First Texas hired Alexandre Tartar and purchased the rights to produce a version of his Manta PI Project. And to quote First Texas engineer Carl Moreland from this thread "Yes, we've hired Alexandre. Yes, we are working on PI. I was personally working on PI before hiring Alexandre, but now we are seriously working on PI."
Another thread with Fisher Manta details
Fisher has not made a PI since the Fisher Impulse was discontinued back around 2013. This collaboration with Alexandre Tartar gives me hope that First Texas can get something out in the next year or two. My bar is low - a waterproof ground balancing PI at least as good as the ATX in a more ergonomic package. Seems fairly doable. Another company that may come out of nowhere all the sudden is Nokta/Makro as we know they are working on a PI. I don't know, but I think this is First Texas' game to lose at this point. So there you go, ATX going up for sale and a spot held open for whatever company can meet the challenge. Good luck First Texas - I am rooting for you!
The following is a compilation from my Rutus testing and useage.
Very long, but anyone wanting some info, this here may help folks.
Btw to my knowledge currently no dealers for this detector line in USA.
They can be purchased from abroad.
The Rutus Alter 71 may not be very well known, but make no mistake a very good detector for what they cost.
There is some comparison info too with other detector models.
Overall weight and feel of unit is IMO nice,,not heavy feeling.
Btw. Concentric measures 8.125" outside to outside diameter.
Supposed 11" dd measures 11".
I even with little time I have run this unit,,this unit designed to be a Deus killer for the $$$. Question is, is it??
Using concentric coil user likely not to dig steel bottle caps, hodograph paints a good pic of junk target,,a backwards C in the meter. Haven't tried DD coil yet to see what happens here.
Depth is dependent on mask setting,,meaning for fringe depth the lower the better.
Interesting how they gave a user options here to have their targets ID in the meter.
Three choices real-- ID is directly reflective of frequency run and conductivity of target.
Then 2 other options,,you can select either 6khz or 12khz for target ID normalization.
So with saying all this here is some data using each of the above selections for target ID.
I should say the Rutus uses a different scale when comparing to most other detectors-- 0-120.
Real ID option selected and frequency selected on detector at max 18.4khz
Normalized setting of 6khz selected,,detector still set to 18.4khz
Normalized setting of 12kh selected,,detector still set to 18.4khz
Frequency changed on detector to 7khz,,real ID option selected
Frequency still at 7khz,,6khz normalization selected
Frequency still at 7khz,,12 khz normalization selected
Preliminary test using 3D test with coin and nails,,detector seems above average with what I see,,,Deus like results,,,not giving either detector yet no advantage,,with time maybe.
Audio,,,Rutus audio not as smooth as Xp Deus,,not as blendy sounding,,leans more toward what I call beeps. This is not meant to say Rutus audio is terrible or anything.
I am still trying to nail down how I want my tones set up using the user programs,,,not there yet.
Does take time though,,user must select each number TID wise and singularly adjust,,,no blocking of groups of tones to adjust.
I do reserve the right here to correct anything I say about this detector in the future.
From what I can tell right now,,Rutus will retain settings when turned off.
Turn back on,,user will need to ground balance though.
Also what ever you have selected,,this is where the cursor will be when you go back in and open menu-- not sure if this happens if you turn detector off though.
Now,,here is where other manufacturers like White's should be paying attention,,Xp as well.
I have read countless Internet forum threads and post associated with just when does the White's V3i and even the Vx3 model need to be ground balanced.
Rutus depending on what you change setting wise will give you ground balance prompt.
This is exactly what White's should have done on the 2 models I mention here.
Xp Deus,,you change freqs,,ground balance doesn't carry over,,should be a prompt..
Now detector companies,,if they do this for future models,,,they could offer a way to override the prompt,,so it doesn't appear in screen. This might be more handy for someone say who is more experience with the detector in question.
Emi,,this detector ranks right up there as being one of the quietest I have run for Vlf,,,even runs as quiet IMO as CTX and etrac,,and DST Fisher units.
Now this from judging in 2 different places with loads of light wires,,and a few transformers.
I should also say,,this concentric coil I received with Rutus is the very first one I have ever owned,,I did run a gents White's XLT with concentric some 6 years ago for around 15 minutes.
Navigating around using Rutus is different,,but not hard,,just gotta get used to it.
Unit seems to ground balance nicely here in my soil.
More to come.
So I was watching the first episode of the new Season 3 of Aussie Gold Hunters, my favourite gold prospecting TV show and the Gold Gypsies on it appear to be using some odd looking new detector, last season they were using GPX 4500/5000's I believe but this season it's some detector I don't recognise, It sounds like a GPX that's sucked on a helium balloon
It doesn't appear to be a Minelab as Minelab tends to put their branding all over things, I can't see any branding on this detector, is it some sort of QED? Even the coils have no branding. It looks like you can adjust the balance on the coil by sliding it back or forwards before tightening the nut.
I really like his pick too that you'll see in the photos, It's nice and sharp up the front but goes extremely wide at the back for good scraping, I wonder what that pick is, I would like one.
--- Update, it's been cleared up already, its a Garrett ATX 🙂 Thanks AU_Solitude

Lanny, there is a super light weight PI built here in Australia, at a good price. I use one and love it. Unfortunately it is not yet available in the USA. It is called the QED. It is being constantly improved by the dedicated inventor. Hope one day you will be able to get one.
