The external screws on the CTX3030 are marine grade 316 stainless steel. These are then blackened for cosmetic purposes. It has come to our attention that a batch of blackened screws used in the initial production run was supplied to Minelab with a faulty blackening process. The issue is typically highlighted when the unit is immersed for some time into sea-water.
The result is that on effected screws the black coating pits and comes off; this is only cosmetic. However, it should not be occurring and certainly affects the overall look of the detector.
This pitting will not affect the integrity of the underlying screw or the detector itself.
Should any customer find that any of the screws on their CTX3030 exhibit the effect as shown in the example above, then please contact your regional Minelab Customer Care Office (contact details are on the Minelab website) and we will arrange, at no charge, to have the screws replaced.
We apologise for the inconvenience.
Should you have any further queries, please do not hesitate to contact your regional Minelab office.
