Getting Started with Your Ace 250
Before heading out on your first hunt, take time to familiarize yourself with your detector’s controls and features. The Ace 250’s interface is straightforward, but understanding each function will significantly improve your detecting experience.
Assembling Your Detector
The Ace 250 comes in three pieces that easily connect. The camlocks ensure a secure fit and prevent the sections from rotating during use. Make sure the coil connector is properly plugged in and the cable is neatly wound around the stem to prevent false signals.
Adjusting the Arm Strap and Length
Proper adjustment is crucial for comfortable, extended detecting sessions. The arm cuff should support your forearm without restricting movement. Adjust the stem length so the coil sits about an inch above the ground when your arm is extended naturally at your side.
Understanding the Control Panel
The Ace 250’s control panel is designed for intuitive operation. Let’s break down each control and its function.
Power/Mode Button
This button turns the detector on and cycles through the five preset search modes: All Metal, Jewelry, Custom, Relics, and Coins. Each mode automatically adjusts discrimination patterns for specific target types.
Target ID Cursor
The 12-segment target ID provides a visual representation of what your detector is sensing. Different metals register at different points on the scale, helping you determine whether to dig or move on. For example, most coins typically register between segments 4-8, while pull tabs often appear at segments 9-10.
Low Battery Indicator
When the battery icon illuminates, it’s time to replace your batteries. The Ace 250 operates on four AA batteries, which typically last 20-30 hours depending on usage.
Pinpoint Button
This feature helps you locate targets precisely within your excavation area. When you get a signal, press and hold the pinpoint button while moving the coil side to side to narrow down the target’s location.
Mastering Detection Techniques
Even the best metal detector requires proper technique to maximize its potential. Here are essential techniques to improve your success rate.
The Sweep Pattern
Maintain a consistent, level sweep about 1-2 inches above the ground. Overlap each sweep by about 50% to ensure complete coverage. Avoid swinging the coil like a pendulum – keep it parallel to the ground throughout the sweep.
Speed Control
Move at a moderate pace – approximately 3 feet per second. Moving too quickly can cause you to miss targets, while moving too slowly wastes time. Practice maintaining a steady rhythm.
Audio Signals
Listen carefully to the audio feedback. The Ace 250’s proportional audio provides different tones based on target conductivity. Higher-pitched tones typically indicate higher-conductivity targets like silver or copper, while lower tones suggest iron or steel.
Discrimination Strategies
Learning to effectively use the Ace 250’s discrimination features will save you time and increase your finds-to-trash ratio.
Understanding Iron Discrimination
The three-level iron discrimination allows you to filter out unwanted ferrous targets. Start with level 2 for general hunting, but adjust based on your location and target goals. In areas with heavy iron trash, you may need to increase discrimination, but remember that this can also eliminate good targets.
Custom Mode Programming
The Custom mode allows you to save your preferred discrimination pattern. After adjusting the discrimination to your liking in another mode, switch to Custom and your settings will be saved for future use.
Balancing Depth and Discrimination
There’s always a trade-off between depth and discrimination. Higher discrimination settings may eliminate trash, but they also reduce your detector’s depth capability. In clean areas, lower your discrimination to detect deeper targets.
Accessory Recommendations
While the Ace 250 works well out of the box, several accessories can enhance your detecting experience.
Headphones
A good pair of headphones not only preserves battery life but also helps you hear subtle signals in noisy environments. Look for headphones with volume control and a 1/4″ connector.
Digging Tools
A quality digging tool is essential. For coin hunting in parks, a hand trowel may suffice. For more serious relic hunting, consider a sturdy shovel or Lesche digging tool.
Coil Covers
Protect your search coil with a durable cover. This inexpensive accessory can significantly extend the life of your coil and prevent scratches that might affect performance.
Maintenance and Care
Proper maintenance ensures your Ace 250 provides years of reliable service.
Cleaning Procedures
After each use, wipe down the control box and stem with a damp cloth. Remove any dirt or debris from the search coil. Never use harsh chemicals or submerge the control box in water.
Battery Management
Remove batteries if you won’t be using the detector for extended periods. This prevents battery leakage that could damage the battery compartment. Always use fresh, high-quality batteries for optimal performance.
Storage Tips
Store your detector in a cool, dry place away from direct sunlight. Avoid storing it with the stem fully extended, as this can weaken the camlocks over time.
Common Issues and Troubleshooting
Even reliable detectors like the Ace 250 can occasionally present challenges. Here’s how to address common issues.
False Signals
If you’re experiencing intermittent false signals, check for loose connections, ensure the coil cable is properly wound, and verify you’re not near power lines or other electromagnetic interference sources.
Intermittent Audio
Check your headphone connection if using headphones. If the problem persists with or without headphones, the issue may be with the control box or speaker.
Reduced Depth
If you notice reduced detection depth, first check your batteries. Weak batteries are the most common cause of performance issues. Also verify that your coil is clean and free from damage.
Real-World Success Stories
The Ace 250 has helped countless detectorists make exciting discoveries. Here are a few notable examples:
Historical Relics
Many Civil War relic hunters started with the Ace 250 and successfully located buttons, bullets, and other artifacts at permitted sites. The detector’s ability to distinguish between different metals proved invaluable in these trash-laden areas.
Modern Jewelry
Beach hunters frequently report finding rings, watches, and other jewelry with their Ace 250s. The detector’s sensitivity to small, low-conductive targets makes it particularly effective for locating gold jewelry.
Coin Hunting
Numerous detectorists have reported finding silver coins from the early 1900s and even earlier using their Ace 250s. The key is researching old sites and using proper techniques to detect targets at maximum depth.
Advanced Tips for Ace 250 Users
Once you’ve mastered the basics, these advanced techniques can help you find more targets.
Grid Pattern Hunting
When searching an area systematically, use a grid pattern. Walk parallel lines across your search area, then turn 90 degrees and repeat. This ensures complete coverage and helps you keep track of where you’ve already searched.
Target Recovery Techniques
Learn proper target recovery to minimize ground disturbance and preserve the site. Cut a neat plug, flip it over, retrieve your target, then replace the plug carefully. In grassy areas, replace any removed turf to leave no trace of your activity.
Research and Permission
The Ace 250 is only as good as the sites you search. Invest time in researching potential locations through historical maps, local records, and talking to longtime residents. Always obtain proper permission before detecting on private property.
Conclusion
The Garrett Ace 250 remains an excellent choice for beginners and casual detectorists. Its combination of user-friendly operation, reliable performance, and affordable price makes it a standout in the entry-level market. By mastering the techniques outlined in this guide and practicing regularly, you’ll be well on your way to making your own exciting discoveries.
Remember that metal detecting is as much about the thrill of the hunt as it is about the finds themselves. The Ace 250 will be your faithful companion as you explore history, enjoy the outdoors, and perhaps uncover treasures that have been hidden for generations. Happy hunting!
