Detector comparison chart

[dfbowers]

Maybe I'm behind a little, but I can't believe that I did not find this earlier.
Interesting reading though!

Very informative! I'm curious about TGSL, how many points would a homemade machine score? Is Nexus fully analog?

Some interesting results in the " tested on Coin targets in the ground (GND) while using some amount of DISC" graph

Doesn't look right to me. Around the Amigo area ?

Think it shows how difficult it is to get meaningful results.

WoW, I find that Meaningless. There was no Base line or Standards involved. You can't compare anything.

[Carl-NC]

Yeah, I remember when that first came out. An impressive effort that produced no useful information whatsoever.

TGSL is castrated version by ivconig of Tesoro Golden Sabre. i can show you TGSL on King Cobra board if delete 3/4 part of details.

Using maths to allow for different coil sizes? There is very little difference between a 6" and 10" coils until you get to pre decimal penny and larger size targets.



Another large test awhile back tested frequency against target size. Some low frequency machines were better than the higher on small targets and some high frequency machines were better at large deep targets.

The only conclusions are.

A it's hard to reliably test detectors
B frequency has little to do with artefact detecting it's the rest of the machine that counts.
C Anyone who detects field here in the UK knows depth has very little to do with finds rate. It's the ability to reliably beep over faint or next to iron at a normal sweep speed.

we can all set up our detectors hotter than normal and gain extra depth on a test garden where you know where the targets are. But on a real field the false signals every swing will drive you mad.

Thats is why I prefer the 1260x over my Bandido or IDX. Sweep slow or fast on faint targets makes no difference it will beep every time. The other two depend on the correct speed. Too slow or fast and it's hit or miss if it will beep.

This is so true.

You speak disrespectful about it.
TGSL has no amplitude regulation and has better detection, that's why I asked it. I know Tesoro circuitry, there is no need for showing anything.

Nexus scored less than tesoro amigo? Shocking! Tgsl is good detector castrated or not. I built one and it performs quite well considering it cost me peanuts to construct. Koala interesting what you said about 1260x. It uses the lm13700 which is transconductance op amp in its circuitry. I been looking for one on eBay. They are rare to find but very good on certain ground conditions.

Be purely down to coil size. Not the machine.

Gentlemen, I read the entire article, line by line, but since I do not speak the language, I was a bit confused.
Personally, help me.
I want a project for me to build, DIY.
What is the most efficient project for gold (mineral)
I do not look for coins or treasure.
Thank you very much for your attention.

i just saw this thread today and i learned some things from these charts plus from my own mixed knowledge i put together that the best detectors are these because of their operating frequencies, depth and discriminating capabilities: mxt, excal/sov/bbs, nexus, tesoros/tgsl, fisher 12**/cz-6, xp deus, equinox... i saw deus has multi freq of 4,8,12,18 as well equinox with its multi freq and that's why they're doing so well with detector sales today. so then from these detectors the best frequencies for both coins and jewlery would be in the range of 3.5, 5, 7-8, 10, 12, 14, 17-18, 25... so if a company could make such a multi frequency detector encompassing all these frequencies( 3.5, 5, 7-8, 10, 12, 14, 17-18, 25) with excellent ground balance, discrimination and depths of a nexus then that company and its detector would be boss, but if anyone could make the same analog version multi-freq detector with the audio being sent through a mini tube amp to create that extra warm analog audio coupled together with planar magnetic headphones in the package then that detector would be king boss
