While the coherer was one of the first radio wave detectors, it had many limitations. Another form of detector that came into use was the magnetic detector, often known as the Maggie for obvious reasons.
The magnetic detector took over from the coherer, especially on maritime installations. It was also used by Marconi for his famous transatlantic transmission in 1901.
It had the advantage that it was possible to directly hear the detected incoming signals. With the coherer any signals were only indirectly heard.
