New Legend Coils And Update

M1 includes 15 khz. The new SMF will be 4 khz and 10 khz, but weighted toward 4 khz. It's getting the frequency below around 10 khz that allows the much better coin ID's on many coins that are masked by nonferrous trash.

 

To elaborate on the above:

It was found that when using frequencies of around 10 khz or above, many coins that are masked by nonferrous trash, will be dragged down the point of giving an ID below nickels. This was shown to be true on the Legend's Park M1 and the Nox's Park 1 (those are the lowest weighted SMF land modes on each detector). It seems to be all about the SMF frequency weighting, so I fully suspect it would be true for all detectors.

The Legend's Beach Mode MW is the combined 4 khz and 10 khz, but weighted toward 4 khz. It was found that MW was giving a very high conductor ID on coins masked by nonferrous trash, but M1 was giving a below nickel ID on a lot of those same masked coins. 

How better will the new SMF mode be compared to M1 when unmasking in nonferrous trash? In my field tests at 4 city parks filled with foil and pull tabs, about 30% to 40% better. More specifically, around 30% to 40% of nonferrous coins that gave a high ID in MW, gave an ID below nickel in Park M1, and would have been missed. 

There is always a give and take when it comes to detectors though. If a detector is made to do one thing exceptionally well, then it typically suffers in another area. This will be true of the new SMF mode as well. The benefit of the new SMF will be phenomenal coin unmasking, but due to such a low weighted SMF, some bottle caps will give a much higher than normal ID.

Also, the last I heard from Dilek, was that the new SMF mode will not be M4, but rather a modified M3. Although Nokta may have changed their mind on that.

BTW- I'm practically drooling for that LG24 9.5x6 coil ?

Question for you Digalicious

since you have been testing the new update can you tell me if Nokta addressed the ground balance issues on highly mineralized ground in the new update, also did they address the issues with the threshold while using wireless headphones

just curious there are some that say the Ground balance is fine, I do not agree with those that say those two things are fine,and I base my statement on my own personal observations of what both my Legends are doing, the GB as well as the threshold is not correct on the Legend, the threshold issue is only while using headphones with out headphones it seems fine

[Digalicious]

D,

Sorry, but I only received the new SMF mode update, not the full update.

I don't know much about the threshold, other than there is an individual threshold volume update on Nokta's site.

I'm not aware of issues when ground balancing on highly mineralized ground. I honestly don't recall anyone mentioning such a issue, other than yourself. Were there others?

Does anybody know what the status on the coils and software update is? I thought they were shipping the coils out last week but I don't see them anywhere?

[Digalicious]

Yes, according to Dilek on Dec 16th, the new coils were supposed to start shipping "next week". That could very well mean shipping on Dec 23th. I don't know if they have shipped yet, or if the European distributers have them yet, but for those in the U.S., with distance and Christmas shipping bottle necks, I'm thinking the U.S. distributers won't have them until the first week of January. Again, if they have been shipped ?

[Digalicious]

It looks like this UK distributor got at least the LG24, but sold out.

Nokta Legend (LG24) 9.5"x6" Search Coil (lpmetaldetecting.com)

EDIT: LG30 says sold out as well.

[HerrUU]

I'm really hoping that 9.5x6 coil will be available soon here in Belgium. Would be a nice addition to the standard 11"

[Digalicious]

Once I get the LG24 9.5x6, I won't be using the 11" ever again. I'm not sure right now if I'll even use the 6" again, but most likely not.

The LG24 will get about the same depth as the 11", plus it's lighter, significantly better at unmasking and separation, and less susceptible to EMI and ground noise.

I'm anxious for that coil too. Just waiting for spring.
