Multi Facet Donger™


Termite and building inspections include the checking of timbers using a timber inspection tool that produces a change in tone when damage or anomalies are present. This tool is typically known as a Donger but is also referred to as a timber Sounder, Tapper, Knocker or Probe.

The Multi Facet Donger (MFD) is the latest innovation from Trade Management Systems (TMS), it has been designed and engineered to reduce the risk of missing timber damage by providing greater surface contact and covering substantially more surface area than conventional tools.
