Merlin McFly compression testing tool

This is the fully CNC machined ‘Compression Testing Tool’ from the Merlin McFly factory. Made from high quality Swiss 7075 alloy, the whole assembly is easily screwed into the glow plug hole of any glow engine with a turbo plug. Once you switch in on and turn the engine to the top dead centre you can read the compression of the engine on the digital readout and compare it with your other engines or those of your friends.
