TSCM Products

+ Details

One of John Little activities while in Government Service was the development of Counter Measures equipment.  This is the basis of Shearwater TSCM today.  Products are continually being updated to combat the ever changing threat and knowledge gained during the ongoing Sweep Service operations is fed back to refine and increase the efficiency.

Two main products are the Shearwater Merlin Mk4 and the Bloodhound.

However, such is the nature of the ever increasing threat a breadth of technology is required for seamless defence.  Shearwater TSCM offers full suits of equipment and all necessary training.
