This Is The Best Setting For Iron Separation With The Legend

[JCR]

Yes, I tried it at TB of 1 & I wasn't seeing an improvement in separation from my normal TB of 7. I do know there is a noticeable difference in separation AND unmasking when the TB moves from +/- 10 Factory default.

Your observation is correct on moving the Tone Break. I don't think you have to go all the way to 0.   6 or 7 work best for me.

Now, play with the Recovery speed. You will be surprised at how much a slower speed improves the audio on co located targets. I have not found a need to go above 5, even in machinegun nails. The only exception I have found so far is in heavy mineralized dirt, 6 or 7 is required. High mineralization soil has been the most challenging for me. The settings have to be just right to get some decent depth & tone.  I'm still experimenting with it. Otherwise The Legend is a very forgiving machine.

Thanks, good to know. 

I didn't take mineralization into account. I have mild ground.

In mild, low mineral ground Recovery can be run low, depending on target density. The Legend also runs very smooth at 0 Ground Balance if there is no more than one mineral bar showing on the Ground Indicator graph. M3 works very well on moist ground. It smooths out the false 11s which are ground ghosts.

I usually have recovery at 3. I'll try 0 ground balance. 

Thanks for the info.
