## Questions & Answers

**Q: How does it work? Does it utilize a laser that you must point to a moving target?**
A: Huh?  Wellll no.  The pickup wire you wrap around the spark plug cable inductively picks up the firing of the spark plug and measures the frequency.

**Q: Will it work on on Mercury 4 strike outboard?**
A: I believe you mean “4 stroke”, and yes, it should work great.

**Q: How long is the pick up wire**
A: A little over 40 inches.

**Q: Will this work on 2 cylinder 4 cycle Lawn Mower Engines?**
A: As long as there is a spark plug,  I don't see reason why not.  You would need to power it up with a CR 2032 battery to lit up the screen.
