How to repair / replace the faulty speaker of the Nokta Makro Simplex metal detector

In this tutorial, I will show you how to repair / replace the faulty speaker of the Nokta Makro Simplex metal detector. Notice that the original speaker has 40 mm diameter, 2 Watt and 8 ohms impedance. I found a compatible one on Aliexpress. I didn't film the case opening, but you can reverse the tutorial to see how it is done. NOTICE that you need a drill and a 1.5 mm spiral drill to unstick the faulty / broken speaker from the Nokta Macro Simplex case. That is not a simple operation, because the speaker is very well pasted with a kind of epoxy resin. I replace it in this tutorial with sanitary silicone, much flexible and easy to replace.
