Upgrade in Minelab CTX 3030

Minelab introduced changes in its CTX 3030 metal detector: strengthened battery box seal and new armrest lock. Upgraded metal detectors are marked with a special stamp.

Enhanced battery box seal


One of the Minelab CTX 3030 disadvantages was the problem of sand ingress into the battery box. It was a serious problem, hunters themselves tried to seal the joint. Since 2016, the Minelab CTX 3030 metal detectors are produced with a new enhanced seal.

New armrest lock


The Minelab CTX 3030 armrest has adjustment – you can move it choosing the most comfortable arm position. But… If you often use this adjustment, the armrest loses its locking ability.
The Minelab CTX 3030 upgrade version has the armrest lock with additional fixing.

How to recognize the upgraded Minelab CTX 3030


The metal detectors that include these updates are marked with a special stamp. Starting from 2016, all new Minelab CTX 3030 metal detectors must have such a stamp.

I am wondering will there be other stamps? Maybe it’s time to produce a New Shaft Lock stamp? The Minelab CTX 3030 shaft that slips out – is it a trivial matter?

In sober fact, the problems of the Minelab CTX 3030 construction are not the most important ones. Personally I am not comfortable with the CTX 3030’s signal processing speed. When the targets are close together, the detector combines the responses. But the manufacturer can hardly solve this issue (at least not in CTX 3030).

  • easy fix on usb port and BATTERY BOX SEAL little rubber seal is thin and not giving the battery compartment a solid waterproof seal.

    i have fitted a slighty thicker seal (o ring ) made from silicone that will not rot in salt water, as divers will use silicone masks over rubber , because the seal is thicker the battery box snaps shut with a “click” nice n tight ensuring its water tight seal ,,,,also a major problem is water getting into usb port that can kill the machine ! i have fitted a O ring and everytime i remove cap to load programs , i will put a small amount of plumbers tape over the thread , before screwing cap back on ensuring a water tight seal,
