SWEEPING SPEED

[Anonymous]

Does anyone know if the speed you sweep the coil of the Explorer over the ground is important?

The slower the sweep the deeper you go. Yes, sweep speed is important, you just have to know when to go slow and when to pick up the pace. Site size, amounts of trash/junk, history, and ground mineralization are all factors in determining sweep speed. When unsure; A SLOW SWEEP should be the DEFAULT SWEEP SPEED.

I agree. The Explorer is an amazing detector but it needs time to process all the data it is collecting and processing. It also needs time to recover and then reset itself for another target. I'll use a moderate swing speed when I am scouting an area but once I start getting signs that I am in a good place I slow WAY down. I think of it a lot like deer hunting. I pretty much just stroll through the woods until I start seeing scapes, rubs, pellet droppings or bedding areas. Then I go on full alert, slow down and scan every inch of ground. hunting for coins and hunting for deer have a lot in common now that I stop and think about it.

I did a lot of testing today with different settings etc. I made a measured rod to insert coins into the ground at different measurements etc. I found that even though almost everyone says to slow way down that if you go too slow on a deep object you miss it. Too fast is bad but I think a medium steady sweep is the best. Too slow and I actually LOST depth and it wouldn't even detect the coin. You can even test this in the air by waving a stick with a coin on it at different speeds and measure the distance to the coil. You will especially see the results when the coin is at the limits of the detector. In pinpoint mode though, you can go relatively slow. I also found that the fast and deep settings make extremely little difference...maybe a fraction of an inch despite what I hear otherwise. I feel that field tests don't lie no matter what you hear or read. -Dave

I guess what we need is some way to measure swing speed. My slow might be your medium which is another guys fast. Maybe inches per second or something.

Sweep speed has a lot to do with the ground conditions.. alot of iron or trash and you want to go slower.. in a clean area you can sweep pretty fast and still hit the deep targets, its just that they might sound like a false at first, so you gotta check em closer with a more deliberate sweep. Also to get maximum depth after hearing the initial target a very quick wiggle motion over the target will give you the best signal.. I'ed say the very slowest I go is about a 4 second sweep in most instances unless in a very high null, then I usually resort to using the same sweep speed but instead of going through a whole sweep, I do multiple small sweeps of about a foot back and forth a few times then move the coil over to the next foot and do it again.. the more time your coil is over a good target in iron the better chance it has to see it.. In clean areas when Im tryong to cover ground I move it up to about a 2 second sweep, then stopping to check closer when I get a chirp...
