Sweep
Techniques Using the Minelab Sovereign
Every time I see a post by a former Minelab user stating they didn't
get more than 4 or 5 inches in depth, I try to figure out how this
can happen. The only things I can come up with are, the sweep speed,
and sweep of the coil itself. I believe first of all the the rod length
is the most important.
Some manuals tell you to make the rod length so that your arm will
hang straight down without bending your elbow, while this is definately
more comfortable, I thinks its a major mistake. If your arm is hanging
straight down with the coil level in front of you there is no way
to make that coil be level with the ground in a complete arc, unless
your sweep is contained to a few feet directly in front of your toes.
It is imperative that the coil on the Sovereign(or any detector) remain
at a constant 90 degree angle to the ground while remaining as close
to the ground as possible. If you think about it, having the arm hanging
straight in front of you will tend to make you swing the coil in an
arc back and forth, making your only full depth capabilty's directly
in front of you. The Sov hates that point where the coil is lifted
from the ground and often false signals any time the coil is lifted
from the ground. If you adjust the length so the coil is flat to the
ground about 1-2 feet in front of you, this will allow a better swing
arc, while keeping the coil flat as you bring it closer to you on
each side. Any one who uses a Sov is aware of the slow sweep required
for the Sov to acheive maximum depth, but perhaps thats the reason
for them not getting the depth. Some can just not swing slow, or cannot
adjust to it. I know I get impatient and want to cover more ground,
I just have to force myself to slow down. The one thing you should
do if you are swinging faster than you should be is to at least take
the time to investigate any thresholdnulls while doing it. The sov
will null on a good target if the sweep speed is to fast. So if you
at least slow down around those nulls, you may be able to get the
sov to respond to the target. This also will enable you to pick up
some good targets near trash. This is the reason I like to keep the
sensitivity down far enough to always have a threshold sound. I know
others turn it up as high as they can with out falsing, but I like
to keep it at the point where the threshold is still there at most
times. I know if your in a really iron infested area that this is
almost impossible, but in most cases 12 oclock on the sensitivity
will still give you a pretty steady threshold sound. Keep the threshold
at a point where it is just barely audible, and investigate any changes
either higher or lower, with a very very slow sweep and wiggle it
quickly over any of the response zones. I hope you guys not getting
the depth can understand what I am trying to say. But for the ones
I see posting you have already given up. All I can say is good luck
with your new detectors, and when you get done hunting out an area,
please post the site here, so one of us that live nearby can come
and give it a soverizing. :)) |
