Metal Detector and PinPointer Performance

[Garrett350@NC]

Many people assume that as long as their metal detector's battery is still showing green and hasn’t completely died, it’s operating at full capacity. But here’s the truth: that assumption couldn’t be further from reality.

As your battery level drops, so does your metal detector’s performance—its sensitivity and depth detection quietly decline without you even realizing it. The same goes for pinpointers, which also suffer from reduced efficiency with a low battery.

And let’s not forget the impact of colder temperatures—freezing conditions can drain battery life even faster, leaving you with less time to uncover those hidden treasures.

1. Reduced Signal Strength​

• Metal detectors rely on a strong and stable electrical current to generate electromagnetic fields. A low battery can result in weaker electromagnetic fields, reducing the detector's ability to detect metals at its usual depth or range.

2. Inconsistent Operation​

• A low battery may cause the detector's electronics to function inconsistently, leading to false positives or missed targets. This inconsistency can make the device unreliable.

3. Weaker Audio Signals​

• Many metal detectors emit an audio tone when metal is detected. With a low battery, the audio output may become faint, distorted, or intermittent, making it harder to identify detections.

4. Reduced Sensitivity​

• Sensitivity settings may not work as effectively with insufficient power, causing the detector to overlook smaller or deeper targets.

5. Premature Shutdown​

• A critically low battery might cause the detector to shut down unexpectedly, interrupting usage and requiring replacement or recharge.

Recommendations:​

• Check the Battery Regularly: Always start with a fully charged or fresh battery before heading out.
• Use the Recommended Battery Type: Stick to the manufacturer's specifications (e.g., alkaline, rechargeable lithium-ion).
• Carry Spares: If you're in the field for extended periods, bring extra batteries to avoid interruptions.
• Monitor Battery Indicator: Most modern metal detectors have a battery level indicator—keep an eye on it.

A well-powered metal detector ensures optimal performance and accurate detection, so keeping the batteries in good condition is essential.

This chart is an expentency based on Ideal conditions. Depending on the batteries being used and quality. Some batteries perform better then others. Some Head phones are better then others when it comes to energy saving. Coils come in different sizes and like everything else so many factors come into play. These results may just be based on one metal detector, Manufacturer etc. Also, while digging is the metal detector turned off or does it remian on? User habits also play a significant roll in battery life.
NOTE: Currently I am working on a project that will allow me to use Dewalt batteries as a power source.

The deus batteries are in the coil/stem/PP/Headphones-they will drain even if not used.
In the traditional older detectors your post was bang on.

Newer detectors, it seems the batteries hold a charge till-bang their dead.
Not a great option either-
Batteries don't like the northern climate either.

This hasn't been true in 30 years or more. Modern detectors are designed with voltage regulators to maintain the same circuit voltage regardless of the battery voltage. The only exception are some high-powered PI detectors where the TX might run directly off the battery. A decently designed detector can run at the same performance right up to the point the battery hits the discharge cliff.
