Deluxe aviation model with dual channel and audible tone. Designed specifically for aircraft magneto synchronization and engine timing. Eliminates all guesswork and provides a greater safety factor by creating perfect timing quickly and reliably. Simply attach three clips to the magneto, and adjust until the illuminated LED turns off (extinguishes) and the tone sounds.
Deluxe model features dual channel (left & right), plus audible tone.
Sounds a different tone when left-in-sync, right-in-sync, and/or both-in-sync.
Uses electronic inductance to accurately signal when points break.
Very compact form factor: 3.125" (79mm) wide x 5.5" (140mm) long x .75" (19mm) high.
Completely safe as it does no use any high voltages (4.5V max test voltage).
Comes ready to use with a 9V battery.
Specifically designed for aircraft use.
