Just lay it next to the spark plug and it instantly picks up the induction from the plug wire and reads out the RPM's. There was no need to connect the included wire for any of the lawn equipment I tried this on. This is easily one of the best little "tools" in my box, and for the price, if / when the battery dies, I will definetely buy another.

It's very accurate. Did not fluctuate much. Definitely work the money very simple too use. Wrap the wire 4 too 5 times around plug wire. Zip tie end back too the wire . Worked great for me. Used it on 4 other 2 stroke engine. ### ⭐⭐⭐⭐ This inductive Tach is a must have. *by K***J on August 31, 2022* Just hold it close to the spark plug and it reads RPM. Also can be mounted on the unit to teach run time hours . So inexpensive I bought two ! Factory settings and carbs with limiter caps do not work up here at 4,000’ . Set the mixture with max RPM at idle and see it back down as you turn the screw , set it down 500 . Then crank it up to Max speed . Look up your unit’s spec and set Torre limit . Now starts well & runs great !!! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/258722983-runleader-digital-mini-tach-hour-meter-tot-hours-accumulate-real](https://www.desertcart.hr/products/258722983-runleader-digital-mini-tach-hour-meter-tot-hours-accumulate-real) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-24*
