hazlewolke Metal Detector for Adults & Kids — 10-inch Waterproof Coil, Adjustable Shaft & Backlit LCD

The Hazlewolke GT690 is an easy-to-use metal detector with a 10-inch waterproof coil, adjustable shaft, and All Metal/Disc modes designed for beginners, juniors, and adults.

Whether you want to spark a child's curiosity or take up a casual hobby, the GT690 balances simplicity and performance. It combines a large, waterproof search coil and a backlit LCD for clear target ID with a shaft that adjusts from 37.6" to 48.8", so the same unit fits growing kids and adults alike. The control box is meant for dry use while the coil tolerates wet environments, making beach and damp-grass hunting possible without worry.

How accurate is the GT690 at finding small targets?

With its advanced processing chip and a wide 10-inch coil, the GT690 can detect quarter-sized objects at shallow depths (about 8 inches under ideal conditions); actual depth varies by soil, target size, and orientation. The larger coil covers more ground per sweep, which improves the chance of spotting smaller items faster than compact coils.

• Detects small coins and jewelry in typical park and beach soils.
• Large coil provides broader coverage for faster searches.
• Performance depends on soil mineralization and target depth.

Can kids use this metal detector safely and comfortably?

The GT690 is designed with families in mind: its telescoping shaft adjusts to fit children about eight years old and up, as well as taller users. Controls are straightforward so beginners can learn to discriminate between trash and valuables quickly, while the lighted screen helps with evening outings.

• Adjustable length from 37.6" to 48.8" for comfortable stance and reach.
• Simple mode switching between All Metal and Disc for learning.
• Backlit LCD for visibility during low-light hunts.

Is this detector suitable for use at the beach or in wet conditions?

The control housing should be kept dry, but the GT690's 10-inch search coil is fully waterproof, allowing you to sweep through shallow water, wet sand, and damp ground with confidence. Avoid immersing the control box and battery compartment to preserve electronics and warranty conditions.

• Waterproof coil for wet sand and shallow wading.
• Control box designed for dry-use only—keep it protected from splashes.
• Works well along shorelines, in puddles, and on damp fields.

How do the detection modes help reduce junk and speed up finds?

The GT690 offers All Metal Mode to pick up any buried metal and Disc Mode to help reject common trash items like nails and pull-tabs. Switching modes lets you focus efforts: use All Metal when you want maximum sensitivity, and Disc when you want to prioritize probable treasures.

• All Metal Mode signals all metals for complete sweeps.
• Disc Mode filters out typical trash to highlight valuable targets.
• Audio cues and target ID on the LCD aid quick decision-making.

Who is this for? The Hazlewolke GT690 suits families, hobbyists, and beginner treasure hunters who want a user-friendly, adaptable detector that grows with the user. It’s an excellent first detector for kids ages 8 and up, teens, and adults who want a sturdy waterproof coil and an intuitive interface for parks, beaches, and backyard searches. If you want a single detector that balances learning features with practical field performance, the GT690 is built to deliver approachable, dependable detecting experiences.
