Core Features and Technical Specifications

The Garrett Ace 350 operates at 8.25 kHz, a frequency that strikes a deliberate balance between depth penetration and sensitivity to smaller metallic objects. You’ll find this particularly effective when hunting gold nuggets in challenging terrain.

The 8.5″ x 11″ PROformance DD coil delivers superior performance in areas plagued by ground mineralization, where standard concentric coils struggle. Its blunted design lets you sweep closer to rocks and obstacles without sacrificing scan coverage. The waterproof coil construction ensures durability when detecting in wet sand or shallow water environments.

You’ve got eight sensitivity levels to fine-tune depth performance against environmental interference. The 12-segment Target ID system provides precise object classification, while Enhanced Iron Resolution with four discrimination segments lets you filter ferrous trash effectively. The detector includes electronic pinpointing to enable faster target recovery and more precise location identification.

Coil compatibility remains limited to Garrett’s proprietary searchcoils, though the included configuration handles saltwater beaches and mineralized soil admirably.

Detection Performance and Target Identification System

Real-world hunting conditions demand more than impressive specifications—they require a detector that translates technical capabilities into reliable target recognition. The Ace 350’s 8.25 kHz frequency delivers exceptional ground discrimination in mineralized soils, while its 12-segment Target ID system provides continuous readout backed by three distinct audio tones.

You’ll separate coins from trash instantly, even in iron-contaminated areas where lesser detectors falter.

The system’s target accuracy proves itself through:

Enhanced Iron Resolution with 4 adjustable segments strips away junk signals in cluttered environments
Electronic pinpointing locates targets within 1-2 inches, minimizing digging and maximizing recovery speed
DD coil configuration penetrates mineralized ground while maintaining precise target separation in tight spaces

The detector excels at identifying small conductive targets like coins and jewelry, making it particularly effective for hobbyists focused on recovering valuable finds in challenging terrain. Its robust design ensures reliable operation across diverse environments, from beaches to open fields, withstanding the rigors of frequent outdoor use.

You’re getting field-tested performance that turns technical capability into recovered finds.

Search Modes and Customization Options

When conditions shift from park hunting to relic recovery, five distinct search modes adapt the Ace 350’s discrimination pattern to match your target priorities. Zero mode eliminates filtering entirely, while Jewelry, Relics, and Coins modes apply factory-optimized settings for specific targets. You’ll cycle through options using the MODE pushbutton, with LCD confirmation of your selection.

Advanced discrimination controls separate valuable finds from trash through Accept/Reject (✓/X) and DISCRIM pushbuttons. Four dedicated iron segments filter ferrous targets, while dark LCD segments indicate accepted signals.

Custom mode delivers complete user customization—program your own discrimination pattern or modify any preset configuration. The Target ID Cursor cross-references with the LCD legend, while eight sensitivity levels compensate for mineralized ground. The unit’s electronic pinpointing feature delivers precise target location coordinates, accelerating recovery time and reducing the size of excavation holes.

This 8.25 kHz platform supports three-tone audio feedback for enhanced target classification. The depth scale displays target burial depth, such as 4 inches, helping you determine the excavation effort required before digging.

Ideal Hunting Environments and Applications

Having configured your search parameters, you’ll want to understand where the Ace 350 delivers its strongest performance advantage. This detector’s materials compatibility with mineralized soils and iron-dense environments makes it exceptionally versatile across hunting disciplines.

The user interface adapts seamlessly to these specialized applications:

Coin and jewelry hunting: 8.25 kHz frequency targets smaller objects while Enhanced Iron Resolution eliminates false signals in cluttered parks and beaches
Relic recovery: 12-segment Target ID distinguishes ferrous from non-ferrous materials in ghost towns and iron-saturated battlefields

Beach operations: Optimized for dry sand detection with notch discrimination for wet sand conditions

Your hunting freedom extends from fresh water to highly mineralized grounds. The 8.5″ x 11″ DD coil maintains stable target identification where conventional detectors struggle, giving you unrestricted access to challenging territories other hunters avoid. At 2.8 lbs, the detector remains comfortable during extended hunting sessions across varied terrain.

Improvements Over the ACE 250 Model

The ACE 350 represents a substantial engineering advancement over its predecessor, delivering measurable performance gains across detection capabilities.

You’ll experience 50% greater maximum depth (150 cm versus 100 cm) and enhanced coin detection reaching 30 cm compared to the 250’s 25 cm limit.

The ACE 350 achieves 50% deeper penetration and extends coin detection range by 5 cm over the previous model.

The upgraded 8.5″x11″ DoubleD coil operating at 8.25 kHz outperforms the 250’s 6.5″x9″ concentric configuration, providing 5.6% to 30% better target response—particularly on historical relics and oxidized metals.

Enhanced iron discrimination with four notches versus two enables superior target separation in contaminated ground.

The DoubleD configuration excels in mineralized soil conditions, maintaining stable detection where concentric coils struggle with ground interference.

Added volume control grants operational flexibility the 250 lacks.

While slightly heavier at 1.27 kg, improved weight distribution reduces sweep fatigue during extended hunts.

The ACE 350’s Target Depth Determination feature provides real-time depth estimates, enhancing excavation efficiency during recovery operations.

Note: neither model supports underwater exploration without additional waterproof housing.

Frequently Asked Questions

How Long Does the Battery Typically Last During Continuous Use?

Picture the sun crossing the sky—you’ll get 25-40 hours of continuous battery life depending on your cell type. Power management favors alkaline batteries, delivering superior runtime compared to rechargeables. Field-tested insights confirm this range consistently across varied conditions.

Is the Garrett ACE 350 Waterproof or Water-Resistant?

The detector’s partially waterproof, not fully water-resistant. You’ll find waterproof features in the search coil and poles, but the control box lacks protection. This limits your freedom to shallow-water hunting where you can keep the housing dry.

Can I Use Different Search Coils With the ACE 350?

Yes, you’ll find excellent coil compatibility across the ACE series. Your search coil options include Garrett’s 5×8″ PROformance, 6″x11″ Viper, and third-party alternatives like Detech’s 18×4″ Widescan—each optimized for specific terrain and target conditions.

What Is the Learning Curve for Beginners Using This Detector?

Your journey from novice to proficient requires 100 hours—mastering metal detector calibration, audio tones, and pinpointing techniques. While beginner friendly features accelerate learning, you’ll achieve true independence through practice, building instinctive target recognition and precise recovery skills in diverse conditions.

Does the ACE 350 Work Well for Beach Metal Detecting?

You’ll find mixed beach detection results—it excels at treasure hunting on dry sand but struggles in wet saltwater conditions. You’ll need to reduce sensitivity by three notches and notch out iron for workable performance in challenging mineralized environments.
