Its been a while since a new metal detector brand has come on the market so when I got a call from Lost Treasure about testing a pair of detectors from a new company I was interested in seeing them.
Chapmans LT Plus was founded in 1995 with the goal of providing low cost, high quality electronics to the US market, with a series of metal detectors included in their product line.
The All-Vision Pro & MD-3010 detectors have been designed to provide features sought by todays treasure hunters. For example, visual target ID is a feature many coin & beach hunters find extremely useful but is typically not found on sub-$200 detectors.
Chapmans engineers incorporated this as well as other features such as depth reading, tone target ID and turn-on-and-go operation into their detectors while keeping a tight reign on the overall price.
Both units tested include VLF circuitry, an LCD display with target ID indication, a waterproof 8 coil, 1/8 headphone jack and use 2 9-V batteries. Discriminate & All-Metal search modes are found on both models, with the MD-3010 also having a Notch search mode. The search coil is hard-wired into the control housing on the All-Vision Pro and removable on the MD-3010 (this allows optional coils to be used when they are available in the future).
The most obvious difference between the two models is the shaft / housing design. The MD-3010 uses a straight shaft with a handgrip on the housing and an adjustable armrest. The shaft length is adjustable by turning the collar on sliding the two-pieces to the desired length. The All-Vision Pro uses the more familiar S-rod with the control housing mounted on the shaft just in front of the handgrip.
The shaft length is adjustable through a locking collar / spring-clip system. Both designs serve their function selecting one is a matter of personal preference.
The MD-3010 is controlled by 7 touchpads on the control housing, an ON/OFF switch and a Volume control. There are three search modes--All Metal, Discriminate and Notch--selected through the 3 mode touchpads. Sensitivity is adjusted by pressing the SENS touchpad and then using the UP / DOWN touchpads.
The Discriminate and Notch controls work a bit differently than on other detectors. When you switch to the DISC mode, maximum discrimination / rejection is in effect (appears as a single black segment on the far right side of the display). At this setting only copper, clad or silver coins (and targets of similar properties) will produce an audio / visual signal.
To accept more targets, press the UP touchpad to add additional black segments beneath the types of targets you are interested in finding. Remember that as more target types are accepted, you will wind up digging more trash as well as good targets. Use the discrimination circuit to eliminate most of the trash in a given area so that you can find more good targets in a given amount of time.
The MD-3010 also features a 3-tone target ID system in which iron, foil, nickels and some jewelry produce a low tone; most rings, pull tabs, screw caps & zinc pennies a medium tone; and coins & silver jewelry a high tone. This is a nice feature especially if you are hunting in dim or no light conditions such as on a beach after the crowds have left and you cannot see the LCD display.
The All-Vision Pro is simplicity itself in that it only has two knobs to adjust. The DETECTION DEPTH control turns the detector on and adjusts the units power output or sensitivity. The TRASH ELIMINATION control is used to select what targets are accepted and which are rejected. The LCD display provides the probable ID of detected targets, battery condition and a dual-segment pinpointing system (segments come in from both edges of the meter and when they come the closest together, the target is directly beneath the center of the coil).
The timing for this field test worked out perfectly as the detectors arrived the day before I flew back up to Pennsylvania. My son Paul, who has been my detecting partner since he was old enough to walk and has become quite a proficient hunter in his own right, wanted to get involved in conducting this field test so we sat down and read over the instruction manual.
We opted to go to a large public park nearby with a section for children called KidsBurg which had the usual assortment of climbing equipment, swings and slides in a wood-chip base which would target recovery a snap. As we unloaded the detectors from the car we noticed someone else from the local club already hunting the area.
Paul turned the MD-3010 on, selected the DISC mode and adjusted the discrimination to accept everything other than Iron & Foil. Signals were not plentiful; however, the MD-3010 did ferret out several coins at depths down to 5.
Pinpointing was accomplished by wiggling the coil over the area where a detected target was found and watching the depth indication on the LCD display. When the shallowest indication was received, the target was under the center of the coil. Practicing this at home on targets youve buried in the yard will payoff in terms of being able to recover targets in the field faster and with less damage to the area you are hunting in.
We spent an hour or so at this location and picked up a number of coins--some had obviously been there a while and missed by other detectorists showing that no place is ever worked out.
Returning to South Carolina, I took both detectors to several local parks and schools to see what might turn up. There hasnt been much rain lately so I stuck to the areas with sand, gravel or wood chips to make target recovery easier. Alternating between the two detectors and in some cases comparing signals, I spent several hours hunting these sites. Coins were recovered in each location, and in most cases, very little trash turned up due to a combination of the discrimination setting and checking the target ID reading before recovering targets.
Chapmans current line of metal detectors wont replace your top-of-the-line detector but that was never their goal. They provide affordable detectors ranging from $89 to $199. Their metal detectors are great for the beginner and some of the more advanced models provide room for growth as well as making a great back-up unit to your primary detector.
The MD-3010 sells for $199 and the All Vision Pro for 159. Both come with a 5-year warranty.
