Hi guys, was wondering if the Detect 4” x 18” gets great depth ? Is it more for covering ground , not so much for depth. Thanks for any info.

I had one on a f75, I was hitting coins and stuff well over 6 inches that's for sure. Found a silver braclett I'll bet easy 6 inches..can't speak for other machines and that coil, but on the f75 it's deep..

That’s ok on just cherry picking.

Nice , like to hear it. I have a F75 and would use it for that detector also. I can get a new one for $109 but it’s for the ATPro. However I don’t feel the Pro is deep. I may be mistaken.
I never used one but my friend used one a lot and it was on the AT PRO and that was the depth he got mild soil at that . sube
Huh???Use mine on both AT Max and Apex, mainly for beach detecting both wet/dry.
Depth on both detectors on wet beach to 10" on a Nickel.

I believe the general rule is that a detector depth is based on coil width not length, Thus a 6" x 18" coil would have a depth of 6" of so on an average size target, But great coverage! The rule of coil width and detecting depth breaks down past a coil width of about 10" or so and this is why a 9" coil is ideal for a lot of detecting and why a 11" standard coil is nearly the same depth as my M15 coil on my Manticore or 17" coil on my CTX 3030. Great for coverage but don't expect much more depth then 11" coil (1-2").

In V3i 7 inches on silver quarter.
Rock solid.
Depends on your machine.
Bought one that was supposed to run on the Bandido 2.
Just doesn't like it.

Hi @Odanscoils .
Was that a Detech Arrow coil for your Bandido II µmax? I always thought it was an original Cleansweap from Tesoro.

I have both.
Ot just didn't like the arrow.
Wouldn't ground balance.
When I got it quiet it couldn't detect anything.
Kept screaming when ever it came close to the ground.

Sounds like the coil was either not compatible or faulty. Detech is usually a very good company so I would suspect there was something wrong with the coil. Maybe the shippers used it as a weapon at some point before you received it...
Arrow would be nice for ground coverage but don't think it would have very good separation. I would think EMI will drastically effect it's depth and id accuracy.
