GS2scope_probeCOP Quick Pick-up Probe
Used for picking up the secondary ignition voltage by placing the tip on top of the ignition coil for the COP (Coil On Plug) / DIS (Direct Ignition System) where the ignition coil is placed on top of every cylinder.



IgnitionProbeHT_1Ignition HT Probe (High-Voltage Cable)
Used for picking up the secondary igition voltage by clamping the high tension (voltage cord of the distributor or the 2 ignition cables of the DLI (Distributor-less Ignition) ignition coil.
