Bit of an update

Did some more extensive bench air testing.
Going to blame some of the poor results of indoor EMI.
Had better results this afternoon when less EMI was present.
I was determined to see what more I could extract in the various modes.

Ground balance will have an impact on detection performance. The Simplex is cable to penetrate black magnetic beach sands but lowers ID #'s.

For 12 grain gold nugget and small gold ear loops, best if no notching is used. Might be the best to use Field mode for prospecting or tiny small gold jewelry hunting. If you plan on notching, only notch the first pixel. Which is the 0-5 disc range. Foil will come in around 15-18, small gold 16-20. As will the small gold. This is an excellent choice for school yard and park hunting.

Beach Mode works excellent with 3 pixels notched, effectively eliminates small iron nails. Somewhat above Tesoros small nail disc setting. Does detect deep on larger coin sized targets. This is one of my choices of modes to use while park, schoolyard hunting when extra depth is needed.

Park Mode, when not looking for Anfibio depth and just coins to 6" deep with accurate tone and ID numbers, if you go by the tones and not the ID numbers you can gain some extra depth.

Overall air test on large cents and large coins and a 14kt gold mans wedding band hover around the 14-16" distance from the coil. Did find that the Simplex does give a better audio report on gold. Better at unmasking gold rings today, depending upon the two targets were orientated on the coil. Found silver coins on edge basically gave the same target ID number as when lying flat.

Best unmasking will be with no notching. If your used to running a detectors using notching and missing good targets, then by all means do notch. For those of us who don't mind hunting with trash noise will benefit from the Simplex's performance.

So for overall hunting gold, silver coins, jewelry, will give the Simplex a higher score today. More enthused about using it in the field.

From a Canadian point of view:
The biggie for me and many Canadians is the ability to detect the clad coinage that is made of nickel plated steel. The good news if your careful you'll find the newer coins that haven't sunk past 3". After that the sound is ratty and they will ID in the iron zone target number 4. Also, all older clad coins before 2010 give a better target signal and ID higher, you'll still have to decide to dig or not. Dimes will be an issue, nickels are the next problematic coins. Now the kicker is, any of these clad coins on edge will ID as 4, rarely 3. I am leaning towards using Field mode to get the best depth on these clad coins. With no notching. To find clad will take some learning of tones, ID numbers before you can be proficient. Now if you don't give a hoot about modern Can. clad and just hunt for copper, brass, silver, gold and relics, the Simplex will perform well for you. Then the above will never be an issue, picking a piece of clad now and then will just be a bonus item.

As for detection of Loonies and Toonies ($1 and $2 coins), shouldn't be an issue locating them even with the newer coins suffering severe depth loss and low target ID numbers as most won't be deeper than 5-6". The older Loons and Toons will come in with a nice clear crisp high sound with a positive ID number. Definitely a Loonie, Toonie machine. If you don't rely on target ID and go by audio, they still can be picked up about 4" or so beyond the ID capability of the Simplex. If you don't care about the clad, Beach mode should be the hot ticket.

Canadians tend to find coin spills on a routine basis. Will be interesting to see how the Simplex ID's them.
So today, I give the Simplex a thumbs up. With high hopes for a smaller sized search coil before spring time.

Just an added note those early Tombac nickels give the Simplex a problem. And choice of wired headphones, audio sensitivity might affect detection results. I have linear volume controls on my headphones as with most. I think a tapered log audio volume control replacement would give a better, finer volume control when using Park 3 tone mode.

Ohh, forgot to add, this may not have anything to do with todays and yesterdays testing results. Today I extended the lower rod further away from the control box. Just throwing this out there.

I dig it with a Nokta/Makro product.

I've started my evaluation of the new Simplex +.

Snow-thrower and Frequency Shift aided my Simplex + work.

I appreiate 'Air Test' aka 'Bench Test' reports.

I feel ther Simplex+ really needs at least two accessory coils.

Headed out the door at 7:15 AM to get to a hunt site.

Joel, overall, the Simplex+ has a lot to offer. Correct.
