Metal-detecting essentials for your next treasure hunt

The lure of treasure hunting is not that of striking proverbial gold (although some still do search for it), but that you never know what historical holdovers the ground will produce. At the right local spot—an old battlefield or remote beach—these tools will allow you to burrow back in time.

1. Search the area

First, you need a metal detector. The Teknetics Patriot can spot booty up to a foot underground, and its display will estimate the object’s depth and material. Audible beeps let you know when metal distorts the electromagnetic field generated by the ­11-inch head. $399

2. Dig a tidy hole

A hand trowel is great for small digs, but if you need to bust through roots or tough dirt, the serrated edges of the 3-foot-long Ground Hawg Shovel will help you cut. Four jabs with the 7.5-inch blade will create a cube-shaped plug of earth that’s easy to replace. $70

3. Be more aggressive

Rocky terrain requires more hardcore tools like the Garrett Retriever II Pick. At 19 inches long, the steel pickaxe features a flat blade for moving earth and a point for cutting. A rare-earth magnet in the center of the head will grab metal objects underwater. $59

4. Get accuracy

Once you start digging, use the 9.3-inch Minelab Pro-Find 35 detector to search the hole. The probe creates a 360-degree electromagnetic field with adjustable power that can sense when it’s within inches of loot. Haptic and audio alerts intensify as you get closer to your treasure. $149
