Hi everyone. --- I recently got back into metal detecting, and bought my 3rd X-terra 705, ( haven't had one for about 4 years)-----I really like the machine, and it is my #2 "go to" machine. --- previously I had every coil that Minelab made for the X-Terra, ---(no Coiltek coils)---- Not wanting to spend that much money this time around, I purchased the "Gold PacK" detector with the 5x10 HF coil. I owned it previously, and really liked it due to it's light weight. ----- I decided to add another coil, so I purchased the Minelab 10.5" 7.5khz coil this week. ------ Long story short, I got out all 4 of my detectors, and did some air tests. --- The winner was another brand with a aftermarket coil, ( but only by 5 points)---- Second place was the 705 with the 10.5", 7.5khz, DD coil----Surprisingly, 3rd place was the 705 with the 5x10DD with the 18.75khz coil. -----I understand that this is an "air test" , but I attempted to put all detectors on a even playing field, --) 0 Disc, wide open sensitivity. -----The end result being very little difference between the 2 Minelab coils, maybe the numbers are different in the dirt, but for what it's worth, I'm putting the 5x10 back on my 705. --- to me, the added weight of the 7.5 DD coil is not worth lugging around for the very small gain in detection ability. ------ Here is the chart comparing the 2 Minelab coils, on the same machine. ---- Thanks for your time.

Great Info! Thanks!
The results of air tests will always be skewed and therefore worth very little. The machine needs something to GB against.
Just for grins, try your test again, only this time set GB to 90 Manual.

Just because he uses the same amount of phase angle shift for compensation, he still can't simulate actual mineral content present in that ground.
