The industry standard for fast & accurate synchronizing of 4 x carburetor / FI throttle valves on 2 & 4 stroke engines. Suitable for 2 & 4 stroke engines. Hook up 6 cylinders with the optional adapter kit.

The easy to use ME (marine) model includes internal rechargeable 1,5Ah NiMH batteries that provide 6 hours autonomy. Recharge the battery with any 12VDC source, such as a vehicle battery or 12VDC adapter while synchronizing.

Bright, water resistant & buoyant holder makes it ideal for on-board marine & external use
Four vertically arranged LED bars (40 LEDs per bar) provide clear visuals even in sunlight.
Shock resistant composite molded polyurethane & polycarbonate casing is strong & resilient. Self calibrates for barometric pressure changes. Solid state medical grade sensors are drop proof.

Three selectable modes provide the total synchronizing solution -
‘RPM’ mode for adjustment of engine speed of 2 or 4 stroke engines during synchronizing.
‘AVE’ mode with 3 overlapping scales from 5 to 55 cmHg & fixed resolution of 0,5cmHg for general synchronizing.
‘DYN’ mode for troubleshooting - allows for immediate visual check why engine cannot synchronize, possibly causes could be a non sealing valve or a cracked manifold.
