Single Frequency vs. Best Data?

Yesterday was my first full day of detecting with the V3. I had a chance to go head to head with the etrac, and I crushed it with my finds!

I did notice a few things in the outing and I wanted some opinions. In Best Data I was able to get a recommended gain up to 12-15, which was a first for me with a full sized coil. I wanted to try to punch a bit deeper to look for small buttons so I thought single frequency 22.5 would be a better choice to concentrate all of the V3's power to one frequency.

The problem is that in single frequency I was only able to get the gain up to 6 or 7 before it became unstable.

So which is better; single frequency with an RX gain of 6 or 7, or Best Data with an RX gain of 12?
 
Neil....isn't it nice to finally see GRASS here in NJ ! I am tired of the beach at this point. Lots of sanded in places.

I gotta get my hands dirty and find some dirt covered coins.
 
I'm sure you will answer your own question, but I wouldn't be surprised if the results are about the same.....for depth anyway.
 
What abut 2.5 or 7.5? Sensitivity is more important than gain, you didn't mention them.

Use the Rx gain to accommodate interference and then to utilize the Disc Sensitivity to optimize depth. For real depth, the important setting is the Discrimination or All metal sensitivity settings. These settings are what make the detector more sensitive to deeper and smaller targets. If background noise is too loud, you will never hear the deeper and smaller targets. Again, you cannot run the AC beyond where it is stable either. Too much Sensitivity will also cause noise and obscure targets and destroy the benefits of a higher level of Sensitivity. I found that in moderate soil the 5HZ Band gave much better depth. I just run the RX up till I get interference then I back off. Then I try to adjust my AC or Disc Sensitivity up till I get interference and back off. The Disc Sensitivity is where you get the depth. The RX Gain is really how loud the signal gets, not the sensitivity to the target. You need it high enough to hear a good signal but not so high as to hear ground interference or outside electrical interference.

On a deep target take the time to try both ways. Make 2 programs, 1 for single, 1 for best data and see why is better. Rob
 
You obviously didn't off-set frequency, because if you had you would have mentioned it.

If you were in the presence of an e-trac then co-interference could have been a problem..

And co-interference was definitely an issue if he got within 100 feet, although it only worked one way. He said my V3 did not interfere with his etrac. I think the auto sensitivity settings and noise cancelling features of his etrac adjusted for this (and my assumption is it cost him quite a bit of depth!)
