- Create a Grid: Divide the area into smaller sections for systematic searching.
- Overlap Your Passes: Ensure that each pass overlaps slightly with the previous one to avoid missing targets.
Slow and Steady Movement
- Move the detector slowly and steadily across the ground.
- Keep the search coil parallel to the ground for optimal detection.
Listening for Signals
- Pay attention to both audio and visual signals on the display.
- Practice recognizing different tones and target IDs to improve your detection skills.
Maintenance of the Garrett CSI 250
Proper maintenance of your metal detector is vital to ensure its longevity and performance.
Cleaning the Detector
- After Each Use: Wipe down the search coil and control box with a damp cloth to remove dirt and debris.
- Avoid Submersion: While the search coil is waterproof, do not submerge the control box in water.
