WHAT IS THE DIFFERENCE BETWEEN LOBE SENSOR AND HALL EFFECT KITS?

Pertronix lobe sensing kits use unique lobe sensor technology, which uses the point cam to trigger, rather than a magnet sleeve or ring. The standard Hall Effect Ignitor module has the integrated circuit triggered by the cobalt magnets in the magnet sleeve or ring that is mounted on the shaft (usually on the cam lobes). Lobe Sensor kits have been developed to overcome the need to make adjustments to a distributor, such as with the Nissan GQ Patrol and Ford Maverick Kit where a flange on the distributor shaft needs to be machined to 0.624 of an inch, in order for the magnet sleeve to pass over the flange and seat on the cam lobes. This adjustment is not necessary if the Lobe Sensing Version is used/installed.
