Saw that video...posted to it... copy below.
I found many errors in your testing!
I call operator error?
X-Terra pro is a different beast and you have to do things differently when switching frequencies, etc. I've been reading the 50+ page manual and have learned a lot...
1. Per the manual you need to do another ground balance any time you switch frequencies. Or it resets back to the default which is in the middle of the scale.
2. The ground you were testing in had lots of iron in it! So why did you leave it in Recovery Speed 1?
1 is low recovery
2. is medium recovery
3 is high recovery
With all that iron in the ground you needed to be on recovery speed 3. (Page 32 of the manual) All that iron at recovery speed 1 was also causing more iratic ID #s too.
3. At the end of the video I saw you do a ground balance over iron which it registered just before that.
Per the manual always do a all metal mode check of the ground you're going to use for ground balance to make sure it's clean before doing this.
Any time you switch frequencies you're suppose to do a ground balance again as the unit will go back to the default setting (per the manual page 16 & 23).
Also, recovery speed 1 gives least sepration. 3 gives the most....never saw you put it on 3 🤔 as you could hear the null iron.
Other things to consider...
This is a prototype of the coming retail unit. Will retail units be the same?
Price will surely be more with all that carbon fiber.
How much bigger is the Simplex coil or just rounder? Many say size matters!
I call for a re-match with all this in mind 🙂
