HOW DO I SWITCH THE FERROUS TONES ON AND OFF?

To disable the ferrous tones OFF simply push and hold the minus button when the PRO-FIND 40 is powered on.
To enable the ferrous tones ON simply push and hold the plus button when the PRO-FIND 40 is powered on.

CAN I SWITCH THE LED FLASHLIGHT OFF?

No, the LED flashlight cannot be adjusted. 

CAN I TOGGLE THE VIBRATION ON/OFF?

No, the vibration cannot be toggled ON/OFF.

WHEN SHOULD I USE THE RAPID RE-TUNE FEATURE?

The rapid re-tune feature was designed so that users do not have to power cycle the pin-pointers to re-tune the PRO-FIND to the environment.
To re-tune the PRO-FIND 40 simply short-press the power button when the PRO-FIND 40 is powered on.

WHAT ADVANTAGE DOES THE ADJUSTABLE SENSITIVITY HAVE?

At maximum sensitivity the PRO-FIND 40 can detect targets at greater distances which can be both an advantage and a disadvantage. To pinpoint a target sometimes it’s better to have a less sensitive probe to reduce the search area, so we have given you the ability to adjust it how you see fit. The sensitivity may also need to be reduced in mineralized or salty soils, so that you are only detecting metal and not the minerals in the ground.

AFTER CONTINUED DIGGING, AND DETECTING A TARGET, I DON’T FIND ANYTHING.

Side detection occurring with the target (or multiple) in the side of the hole. Use the tip of the probe to check around the sides of the hole. Reducing the sensitivity can also help.

CAN I USE MY PROFIND 40 WHEN I’M GOLD PROSPECTING?

Yes, but be aware that it won’t have the same sensitivity to very small nuggets as a quality Minelab metal detector. It will be a good aid in target recovery for larger nuggets.

CAN I WASH MY PROFIND 40?  

Yes, the PRO-FIND 40 is waterproof to 3 meters (10ft) and can be washed. When washing always use clean fresh water.

HOW DOES THE AUTO POWER OFF SYSTEM WORK?  

If no targets are detected or buttons pressed for 5 minutes, then the PRO-FIND 40 will start a slow constant beep (Lost Alarm). This alarm will sound for 5 minutes and then the PRO-FIND 40 will power off to save battery life.

WHY IS MY PROFIND 40 NOT POWERING UP?  

The battery may be flat or inserted incorrectly. Replace the battery and/or check the battery orientation. If you are still having issues, contact your closest Minelab Service Centre.

THE LIGHT COMES ON AND THERE ARE 2 BEEPS, BUT NO DETECTION OCCURS, WHY?  

The PRO-FIND 40 has a 3rd beep that notifies you that the pin-pointer has calibrated to the environment. This can sometimes take up to 30 seconds to occur depending on environmental conditions. You can short press the power button to perform a rapid re-tune. You should then hear a confirmation beep and the PRO-FIND 40 should now detect metals.

GENERAL TIPS  

Tips for switching on:

Make sure there is no metal close to the probe.
Listen for the third beep (short) before trying to detect any metals.
If it has been a long time since the unit was last used (several days) or there has been significant temperature change since its last use, then it may take up to 30 seconds to calibrate.
Calibration usually takes less than a second when the unit has been used recently.

In highly mineralized soils:
You may need to use the rapid re-tune feature, particularly if the soil has variable mineralization levels.
You might benefit by reducing the sensitivity to ensure smooth operation.
