Watch the video test: Mars Discovery coil for Makro Racer. Plus a photo report and comparison with the original coil. It was interesting to try an off brand one.
The video test. Firstly, I was interested in finding out whether the Makro Racer still remained capable of separating the targets. Secondly, I wanted to make sure the VDI remained the same.
