Detector Care and Safety (Continued)
MAINTENANCE OF PARTS
Tightening the Camlocks
The plastic parts of the Camlock stretch slightly during 
normal use and may need adjusting periodically (every few 
months of regular use). 
Adjust the Camlocks to reduce the tension prior to storing 
the detector for a month or longer.
1.  Open the Camlock.
2.  Gently tighten the 
Thumbscrew in small 
increments.
3.  Close the Camlock.
4.  Check after adjustment by 
applying normal force to 
the Shafts. 
5.  Repeat until the Shafts do not collapse easily under 
normal force.
Do not over-tighten the thumbscrew as this may 
damage the camlock parts.
Battery Maintenance
Lithium-ion battery performance may degrade if unused for 
long periods of time. Fully charge the battery at least once 
every 3 to 4 months to prevent this from occurring.
Even with correct care and maintenance, Lithium-ion 
battery performance reduces over time with normal use. 
Therefore the battery may need to be replaced every few 
years. Replacement batteries can be supplied and installed 
by a Minelab Authorised Service Centre.
Do not apply any chemicals including O-ring 
lubricant, grease or silicon grease to seals or 
O-rings if replacing the internal battery, as this 
will damage the battery seal.
Coil Maintenance
The Skidplate is a sacrificial/replaceable part intended to 
protect the Coil from damage. Replace the Skidplate when 
it becomes excessively worn, but before it wears through in 
any place.
After Beach/Saltwater Detecting
Sand is abrasive, and salt can corrode metal parts of the 
detector over time. Following the listed advice is essential 
to avoid damage to parts of your detector.
Removing Sand From the Detector
Immediately after detecting at the beach or in saltwater, 
rinse all parts of the detector with fresh water. Avoid 
wiping the detector to remove sand as this may cause the 
sand to scratch the detector.
Open both Camlocks and flush with clean fresh water.
Remove the rubber Shaft Bung then flush the insides of 
the Shafts with clean fresh water.
Headphone Socket Maintenance
Immediately after underwater detecting sessions, make 
sure that the area around the connector is dry and free of 
sand/mud before disconnecting the headphones (or the 
waterproof dust-cap).
If any sand/mud accidentally gets inside the Headphone 
Socket, flush it gently with fresh water before drying it 
thoroughly.
ML 105 Headphones Maintenance
