Garrett AT Max

The AT Max is the most powerful single-frequency model in Garrett's All Terrain series. It runs at 13.6 kHz, a frequency that balances depth on coins and relics with good response to smaller items, and it is built for dust, humidity, rain and shallow water, making it well suited to Pakistan's hot, dry fields as well as riverbeds. Its rugged build has made it a favourite with relic hunters worldwide.

A True All Metal mode and eight sensitivity/depth settings let experienced users push for maximum depth, while Iron Audio lets you hear discriminated iron so you can judge whether a signal is worth digging. Garrett's automatic ground balance with its exclusive Ground Balance Window helps it cope with mineralised soil, and a 0-99 digital Target ID and adjustable threshold give clear target information.

The detector has a backlit display for early-morning or evening hunts and built-in Z-Lynk wireless, and the package includes CS-3 wireless headphones and four AA batteries. It is fully submersible to 10 feet (3 m). For relic hunters at old forts and settlements, and for anyone who wants a tough single detector for all ground types, the AT Max is a strong choice.
