Daniel. on Spectra V3i.. you can use 3 things to eliminate Emi...
1. use the Offset Frequency function ..and find the most stable channel of 3Fmultifrequency /or also F1 frequency/..

2. use TX Bost ON and at the same time reduce the level reduce the RX gain level.*/ rx gain 5-8 max!!!/.. so the detector gains stability in EMI... and at the same time you can also obtain a deep range... even in various mineralized terrain... provided you use the correct  high ground filter...

I would keep the sensitivity of DS at the level of DS 88 and DS 92 to obtain the best depth of detection..

 

3. use band pass type ground filters - these are more resistant to emi.. and 5Hz band, 7.5Hz band, 10 Hz band, or 12.5 Hz band filter. _according to the level of mineralization of the terrain... and also set Modulation of sound ... to a low value up to 3 max ... then the detector does not amplify weak audio signals,,
...a 12.5hz high filter can also be very resistant to EMI, but it is very shallow.../it is good in 2D separation/

  One more thing. For fast operation of the detector, set the recovery delay to 25-30.max. in combination with a 10hz band filter or a 12.5hz band filter. max, and the V3i Spectra is fast enough but also deep enough...

if you work in mix mode, you can also use a faster SAT...for example on value 15-20 SAT....and the detector will process targets from the static all metal channel faster....

Amazing, spun my head around. I spent 4 weeks studying for the Amateur radio license, Aced the test. I learned the right answers to pass the test.  But what did those answers mean?  Amazing amount of options in the Spectra V3i. 

 Makes me wonder if the person who programed the software ONLY worked on the Spectra V3i.  You would think someone with that ability would have been good working the MX Sport. 

 It's too hot, 90's here in WV so  I'm programing and bench testing the Sport.  3 by 5 cards for each program.

The V3i I had was also badly affected by EMI and I can say the

Wish I had know this information when I owned the V3i.

Been thinking of visiting the man I sold the V3i to and see if he might part with it.  Accordingly from him the detector has not been used not even one time in well over 5 years.  He actually bought it to hunt for arrows he loses while either hunting for target practice.

This just arrived at my doorstep yesterday from the original purchaser.  I can't wait to take it out.  I haven't swung this model in years.  When they first came out I thought they were very complicated.  I felt the same way about the XLT and DFX.  For some reason being a decade older makes a difference.   The coolest thing is all the coils will also work on my DFX!

You are all set!

Congrats on the purchase! The V3i is one of the most underrated machines out there. The target analysis capabilities were way ahead of their time… Kind of makes the advanced 2D Target ID on my Manticore look primitive.

Way ahead of it's time.  Plus, the screen is color.  I can't believe we're still looking at black-and-white readouts on Metal Detectors.

Unfortunately, this tech is too complicated for Garrett to do anything with it.  They like to keep things simple!
