Finally, Pro Mode, also known as Pinpoint Mode, narrows the search area, precisely locating a detected target․ Use it after a signal is found in other modes for accurate digging․ Understanding these modes and their applications is crucial for maximizing your detecting success and efficiency․
All Metal Mode
All Metal Mode on the Garrett Ace 250 is your foundational setting for detecting all types of metallic objects, regardless of their composition․ This mode maximizes detection depth, making it perfect for locating deeply buried targets․ However, it doesn’t discriminate – you’ll receive signals for iron, aluminum, gold, and everything in between․
It’s best used when you want to identify everything present, or when prospecting in areas where you don’t want to miss potentially valuable finds․ Remember to dig all signals, as identifying targets relies solely on audio cues and digging․ This mode is a great starting point for learning the land’s signals․
Discrimination Mode
Discrimination Mode allows the Garrett Ace 250 to filter out unwanted metallic targets, like iron and aluminum, saving you time and effort․ Using the discrimination settings on the control panel, you can ‘notch’ out specific target IDs, effectively ignoring signals from those materials․ This is incredibly useful in trashy areas, focusing your efforts on potentially valuable finds like coins and jewelry․
Experiment with different discrimination levels to find the optimal balance between rejecting trash and retaining desirable targets․ Remember that higher discrimination levels may reduce detection depth for all targets, so adjust carefully!
Pro Mode (Pinpoint Mode)
Pro Mode, also known as Pinpoint Mode, is activated by pressing the pinpoint button on the control panel․ This mode narrows the detection field, allowing for precise localization of a detected target․ Unlike standard search modes, Pro Mode doesn’t display a Target ID number; instead, it provides an audio tone that increases in pitch and volume as you move the coil closer to the center of the target․
Use pinpoint mode after a target is initially detected in another mode to accurately center the coil over the object before digging․ This minimizes the size of the hole and speeds up recovery!
Interpreting Target ID Numbers
The Garrett Ace 250 displays Target ID numbers ranging from 0 to 99, offering a guide to potential target composition․ Lower numbers (0-20) generally indicate iron or junk, while higher numbers suggest more valuable finds like silver (60-69) or copper (63-79)․ However, these are estimates, heavily influenced by ground conditions and target depth․
Don’t rely solely on the ID number! Consider the audio tone, signal strength, and surrounding environment․ A fluctuating or weak signal might indicate a deep or corroded target․ Experimentation and digging practice are crucial for accurate interpretation and successful recoveries․
Ground Balance: Achieving Optimal Performance
Ground balancing is vital for the Garrett Ace 250’s performance, minimizing interference from minerals in the soil․ Incorrect ground balance causes false signals and reduced depth․ The Ace 250 features automatic ground balance, simplifying the process for beginners․
