Take a look at this pic.
Ruler in inches in pic to show length of nail,,and provide scale.
Down the barrel sweep using 11dd coil,,Rutus will alert on coin.
I used max freq setting,,even ran disc up to 40.
Reactvity 2 and higher a requirement here though,, reactive setting 3, and 4 provided more sweep speed.
Rutus won't tell you what the coin is conductive wise,,but gives good tone.
Notice Rutus coil is 11" wide,,,in the video above that coil narrower than Rutus.
This what is happening here with Rutus not all about recovery speed.
And I can say the same thing about so Deus.
And before some here go off the deep end.
Would Rutus or even Deus pick this target scenario (the coin) up if buried 8" and down the nail's barrel is swept?
NO
But what about an inch?
This what the Rutus does here,,Deus too,,is all relative,,,and in the end does give more odds of detecting a coin in a similar scenario with just one pass of the coil.
Sure I can rotate the sweep of the F19,, even F 75 and get the coin in the video above,,and my pic too.
But when we hunt a site,,we may never approach from this scenario from a detectable angle.
How many 6" squares in a site??
And how many angles can they approached from?
How many 3" squares in a site?
How many angles can they be approached from.
I could go on and on,,,get the idea??
This is one of the reasons Deus users are kicking butt.
