Getting Started with Your Garrett ACE 250
The Garrett ACE 250 metal detector is a fantastic choice for beginners and seasoned detectorists alike. This versatile machine offers excellent performance without overwhelming you with complicated features. When you first unbox your ACE 250, you’ll find the control box, search coil, and adjustable shaft that breaks down into three pieces for easy transport.
Setting up your ACE 250 is straightforward. Start by assembling the three shaft pieces and securing them with the camlocks. Make sure the search coil cable is properly connected to the control box and wound around the lower shaft to prevent snags while detecting. The ACE 250 runs on four AA batteries, which typically last between 20-30 hours of detecting time.
Understanding the Control Panel
The control panel on the ACE 250 is intuitive and user-friendly. The LCD screen displays target identification, depth readings, and battery level. The five search modes (All Metal, Jewelry, Custom, Relics, and Coins) allow you to filter targets based on your hunting goals. The sensitivity and discrimination controls let you fine-tune your detector’s performance based on ground conditions.
Mastering the Basic Settings
Sensitivity Settings
The sensitivity control on your ACE 250 affects how deep your detector can search. In areas with minimal interference, crank it up to maximum for the deepest detection depth. But in locations with electrical interference or mineralized soil, you’ll need to reduce sensitivity to maintain stable operation. Start at mid-range sensitivity and adjust based on your results.
Discrimination Mode
Discrimination helps you filter out unwanted targets like nails and pull tabs. The ACE 250 offers eight segments of discrimination, allowing you to accept or reject specific types of metal. For general hunting, the preset modes work well, but you can create a custom mode by adjusting the discrimination levels to match your specific hunting environment.
Search Techniques for Better Finds
The Proper Swing Technique
The key to successful metal detecting is developing a consistent swing technique. Keep the search coil parallel to the ground and maintain a consistent height of 1-2 inches above the surface. Overlap each swing by about 50% to ensure complete coverage. Move at a steady pace – about one step every 3-4 seconds is ideal for thorough searching.
Pinpointing Your Targets
When you get a signal, use the pinpoint button to precisely locate your target. Center the search coil over the strongest signal point and press and hold the pinpoint button. Move the coil slowly from side to side to find the exact location. The depth indicator on the LCD screen gives you a good estimate of how deep to dig.
Essential Accessories for Your ACE 250
Headphones
While the ACE 250 has a built-in speaker, using headphones significantly improves your detecting experience. They help you hear faint signals, block out background noise, and extend battery life. Look for headphones with a 1/4-inch jack that provide good audio quality without breaking the bank.
Digging Tools
A good digging tool is essential for recovering targets without damaging them. The Lesche digging tool is a popular choice among detectorists, offering durability and precision. For softer ground, a sturdy hand trowel works well. Always fill your holes and leave the area as you found it.
Common Issues and Troubleshooting
False Signals
If you’re experiencing false signals, check your sensitivity setting first. High sensitivity in mineralized soil or areas with electrical interference can cause erratic behavior. Also, ensure your search coil cable is properly wound and not touching the coil itself, as this can create interference.
Battery Life Concerns
If you notice your batteries draining quickly, check for any corrosion on the battery contacts. Using high-quality alkaline batteries or rechargeable NiMH batteries can improve performance and longevity. Always remove batteries if you won’t be using your detector for extended periods.
Advanced Tips for Better Results
Ground Balancing
While the ACE 250 doesn’t have automatic ground balancing, you can manually adjust for mineralized soil by reducing sensitivity until you get stable operation. In highly mineralized areas, you might need to lower sensitivity significantly to maintain performance.
Target Recovery
When you’ve pinpointed a target, cut a neat plug by making a horseshoe-shaped cut in the grass. Fold back the sod carefully, recover your target, and replace the plug. This method preserves the lawn and makes your detecting less noticeable to others.
Maintenance and Care
Cleaning Your Detector
After each hunt, wipe down your ACE 250 with a clean, dry cloth to remove dirt and moisture. Check the search coil for any cracks or damage. Store your detector in a cool, dry place away from direct sunlight when not in use.
Annual Check-up
Once a year, inspect all components for wear and tear. Check the coil cable for any breaks or fraying. Test all controls to ensure they’re functioning properly. If you notice any issues, contact Garrett’s customer service for assistance.
Where to Hunt with Your ACE 250
Public Parks
Parks are excellent locations for finding coins, jewelry, and other modern relics. Focus on areas around old trees, benches, and playground equipment where people tend to congregate. Always check local regulations before detecting in public spaces.
Old Home Sites
With permission from property owners, old home sites can yield amazing finds. Look for areas where people would have gathered, such as near porches, walkways, and old outbuildings. Research the history of the property to identify the most promising areas.
Comparing the ACE 250 to Other Models
ACE 250 vs. ACE 300
The ACE 300 offers more advanced features like digital target ID, iron audio, and higher frequency operation. But the ACE 250 remains a solid choice for beginners due to its simplicity and reliability. The ACE 300 might be worth considering if you’re looking for more advanced features as you gain experience.
ACE 250 vs. Other Brands
Compared to other entry-level detectors, the ACE 250 offers excellent build quality and performance. While some competitors might offer similar features at lower prices, the Garrett brand reputation and customer support make the ACE 250 a worthwhile investment.
Getting the Most from Your ACE 250
The key to success with any metal detector is practice and patience. Spend time learning how your ACE 250 responds to different targets in various soil conditions. Keep a log of your finds and the settings you used – this information becomes invaluable as you develop your skills.
Remember that metal detecting is about more than just finding treasure. It’s about getting outdoors, learning history, and enjoying the thrill of discovery. With proper care and technique, your Garrett ACE 250 will provide years of detecting enjoyment and help you uncover countless treasures waiting just beneath the surface.
