Introduction. Metal detecting at a swim beach or
in the beach water is one of the major detecting attractions in the hobby.
Generally, there are very specific detector requirements for metal detecting
on freshwater and saltwater beaches, however, target recovery scoops can be
used on either type of beach and in fresh or salt water.
A common target recovery tool used at the beach is a sand or water scoop.
The scoop will have a basket or bucket with holes in the basket to filter
the sand, a cutting edge and a handle to grip the scoop. There are many
different types of scoops and each type will have some positive and negative
attributes. Scoop price can also be a very important factor in purchasing a
scoop; however, getting the right scoop regardless of price is very
important since recovering targets from the beach or in the water can at
times be very difficult.
There are two basic types of scoops.
Scoops used in the beach dry sand and occasionally in the wet sand usually
have short handles, wire mesh screen for the basket and a steel cutting lip
wedded to the mesh basket. The basket size for a sand scoop can be from four
to five inches in diameter and may hold one to two quarts of sand.
Scoops used in wet sand and the water are usually constructed of stainless
steel or aluminum with a handle length of 42 to 48 inches. The bucket size
will range from five to six inches in diameter and nine to twelve in depth.
Keep in mind that one quart of wet sand weights 4.3 lbs and the larger the
scoop you have the greater weight you will be lifting. Sand weight is an
especially important attribute to consider before purchasing a very large
bucket (6x12 or larger) water scoop.
Sand Scoops. This type of scoop can be constructed of plastic, galvanized
steel, aluminum or stainless steel. The basket size will usually range from
four to five inches in diameter with holes for filtering out the sand of one
/ half inch in diameter. The holes in the basket can be either square or
circular.
Sand scoops will usually range in price from $20 to $40 depending on the
design of the basket, material used and length of the handle.
In Fig. A there are four sand scoops, each of
these scoops has a handle directly mounted to the scoop basket. The four
scoops in the figure are either plastic, galvanized steel or stainless
steel. The issue with these scoops is that they should only be used in dry
sand. There is just no leverage of your swinging power since the handle is
mounted directly to the basket. Another issue is that all of the sand's
resistances against the scoop's basket are transmitted to the detectorist
wrist and lower arm. Over a period of time the wrist and lower arm can
become sore.
In Fig. B you will find photos of two 90 degree
straight handle sand scoops. The first scoop has a handle extension while
the second scoop has a short handle. Straight handle scoops can be used in
dry sand but using them in wet sand requires much more swing power from the
detectorist arm since the handle mounting angle is 90 degrees to the basket.
90 degree handle scoops do not have the same leverage from the detectorist
swing as does a 20 degree handle scoop. The scoop with the extension does
not have a kick plate on the basket. This scoop should not be used by
applying pressure from one's foot to force the basket into the sand as doing
so will damage or crush the basket in a short period of time.
In Fig. C is the ideal sand scoop for target
recovery in beach dry sand. The handle is welded to the scoop basket at 20
degrees and is eight inches long; the basket diameter is five inches with
1/2 inch holes in the screen mesh. This scoop will provide the best swinging
leverage in soft sand and can also be used in wet sand by drawing the scoop
across the sand toward the detectorist. The ideal material for this scoop
would be galvanized steel for the handle, basket and cutting lip. Using
galvanized steel will provide for light weight, a smooth travel though the
sand and be somewhat resistant to corrosion.
Water Scoops. The two main materials used in water scoop construction are
stainless steel and aluminum. There are water scoops made of galvanized
steel but the durability of the scoop may not be as good or long lasting.
The typical scoop (bucket) size is five or six inches with either 1/2 inch
or 5/8 inch holes.
The hole size you choose should be determined by the type of lake or ocean
bottom you will be detecting and recovering targets. I would suggest using
1/2 inch holes since smaller objects will not as easily pass though the 1/2
holes in the scoop.
Tip: Cover the inside bottom of the scoop with 1/4
inch mesh galvanized screen and secure it with small tie wraps, both screen
and tie wraps can be purchased from your local hardware store. This will
keep the small earrings and other small items inside the scoop rather than
flow though the larger 1/2 inch holes back into the water as you shake the
scoop.
All scoops made from stainless steel or aluminum can be forced into the
beach bottom or sand by applying pressure to the back of the bucket with
your foot. These scoops have very rugged construction.
Aluminum scoops will weight from three 1/2 to four lbs, while a stainless
steel scoop will weight from six to six 1/2 lbs. The price for aluminum
scoops will range from $120 to $150 while the price for a stainless steel
scoop will range from $145 to $190.
In Fig. D is a 48 inch length handle aluminum
water scoop. The handle is welded to the scoop bucket (basket) at an angle.
The ideal angle of the handle to the scoop is 20 to 35 degrees. You will
also note that there is a support piece welded between the handle and the
bucket. This particular scoop bracket is square. A better choice would be a
round piece of aluminum tubing. The reason for a round support piece of
tubing is that this is the area you will grip to shake the scoop for sand
removal. A round metal support is much easier on the hand while gripping and
shaking the scoop.
In Fig. E you see an aluminum scoop with a travel
handle. The handle comes apart in the middle for easy transportation in your
car or on an airplane. A travel water scoop can be obtained in either
stainless steel or aluminum construction materials.
In Fig. F you will see a stainless steel
scoop. The ideal stainless steel scoop will have a 48 inch handle welded at
20 to 35 degrees to the bucket with a round support piece from the handle to
the bucket. The bucket should be five inches in diameter, nine inches deep
and the hole size should be 1/2 inch in diameter. This scoop should also
have a travel handle.
Fig. G has two images. One image has a grip welded
to the handle. The grip is there to made it much easier to lift the scoop
once it is full of material from the beach bottom of a lake or ocean. This
type of grip can be purchased and added to any aluminum or stainless steel
handled scoop. It does not need to be welded to the handle.
The other image is of a stainless steel scoop bucket. Note the bill on the
scoop bucket is long. This long scoop bill helps in penetrating deeper into
the beach bottom and adds to the amount of sand that can be removed with
each bucket dig.
In Summary. Selecting the right scoop for beach
and water target recovery is very important. You must be prepared to spend
money, since a cheap scoop will probably not last long or produce the
desired target recovery result.
In Fig. H is a summary table of sand and water
scoop attributes.
The most important attributes are handle angle, basket or bucket size and
material used to construct the scoop.
There is a Scoop Recommendation list of attributes for both sand and water
scoops at the end on Fig. H. Take some time to review the complete table
before purchasing your next scoop.
In conclusion you will probably be purchasing both a sand scoop and a water
scoop. These scoops can usually be used on either freshwater or saltwater
beaches.
The major reason for stainless steel water scoop is the durability of the
stainless steel in saltwater and hardness of the stainless steel for digging
in freshwater rock bottom beaches.
