PROS / It packs great features like notching and sensitivity into a small, comfortable package.
CONS / Troublesome recovery time can make sorting between targets in trashy areas a real chore.
VERDICT / It's not the most advanced beginner detector available, but White's Coinmaster Pro is easy to use and has a lot to love.
White's Electronics is one of the oldest manufacturers of metal detectors in the world. Their proven devices look a little dated, but they have features to impress beginners and veterans alike. The Coinmaster Pro is an all-purpose detector, but it's been optimized for coinshooting and relic hunting. You'll find gold rings and jewelry with it here and there, but its strengths are in finding change that's long been buried beneath the ground.
In terms of design, the Coinmaster Pro is simple and classic. A small control box is mounted just below the lower curve of its S-frame, and its adjustable shaft locks snugly into place. The entire device weighs a meager 2.5 pounds, making it one of the lightest detectors you can buy. Its arm cup isn't padded, but its finish is smooth and its edges curved, so your arm won't be pinched or chafed raw after a few hours of use. It's a machine that's meant for the long haul.
White's has packed a number of features into this little device, from an easy-read depth ID to an eight-segment target ID complete with variable discrimination and custom notching. Three-tone audio and adjustable sensitivity round out its rather impressive selection. It doesn't have adjustable ground balance, but its sensitivity settings should give you enough control to weed out ghost noise from highly mineralized soil.
The Coinmaster Pro's biggest failing – and the reason it doesn't rank higher on our list of the best general-purpose metal detectors – is its slow recovery time. After the Coinmaster has passed over and spotted a piece of junk metal, it takes a second or two to reset before it can spot anything else. If you're detecting in a field where objects are far apart, recovery time isn't much of an issue. However, in areas with a lot of trash, a detector with a low recovery time can mean you’re likely valuable finds. You can mitigate the problem by sweeping a little more slowly and doing several passes over an area, but in trashy areas this quickly gets tedious.
Recovery time aside, the Coinmaster Pro is an excellent, easy-to-use, comfortable device with features that impress. If you're not planning on scouring areas that are high in junk metals, it will do a good job helping you find treasure below the surface.
