Uncover Hidden Treasures Beneath Your Feet
Turn any outdoor adventure into an exciting hunt with this versatile handheld detection tool. Whether you're combing sandy shores, exploring creeks, or scanning fields for forgotten relics, its dual-mode operation lets you target specific valuables or sweep for everything metallic. The waterproof search head expands your hunting grounds to shallow water zones where lost jewelry and coins settle over time. With adjustable length settings, comfortable grips, and an intuitive control panel, you'll enjoy hours of comfortable exploration. Depth capability reaches over 7 inches for coin-sized objects, and the audio-plus-visual indicator system ensures you never miss a signal—even in noisy environments.

Why You Need This
- Deep Scanning Power: Locates targets more than 7 inches underground, revealing items other tools miss in mineralized soil or packed sand.
- All-Terrain Versatility: The submersible coil lets you search riverbanks, lakeshores, and tide pools where valuables accumulate, while the control box stays dry above water.
- Selective Filtering: Switch to discrimination mode to ignore common trash metals and zero in on precious materials like gold, silver, and bronze, saving time and energy.
- Fatigue-Free Hunting: Telescoping shaft adjusts from 31 to 42.5 inches, with a padded handle and forearm brace that distribute weight evenly for all-day comfort.
- Beginner-Friendly Design: Clear visual meter and loud audio alerts work together to guide you to buried finds, no learning curve required.
- Extended Battery Life: Low power draw means fewer interruptions—hunt longer on standard 9V batteries (two required, sold separately).

What Our Customers Say
Discover what makes THOMLER special.
Adjustable shaft fits my height perfectly, way more comfortable than expected for long sessions.
Discrimination mode helps avoid digging up bottle caps and rusty nails constantly.
Been hunting for three weekends now and found some old coins in my backyard that I had no idea were there. The audio alerts are super clear even when it's windy outside.
The telescoping design is convenient for storage, and the padded handle really does make a difference when you're out there for hours scanning fields.
My teenage son wanted to try metal detecting as a hobby, and this unit is straightforward enough that he figured out the controls in minutes without me hovering over him the whole time.
