## Overview

The GTC TA100 Smartach+ is a rugged, wireless ignition analyzer and tachometer designed for professional-grade diagnostics. It measures spark plug voltage up to 50,000 volts and RPMs from 200 to 20,000 with 0.05% accuracy, supporting 1 to 12 cylinder engines across multiple ignition systems. Its quick, wire-free setup and clear LCD make it an essential tool for precise engine tuning and troubleshooting.

## Description

The TA100’s unique and proprietary technology allows the user to perform quick and reliable diagnostics of non-starts, misfires, fouled up or damaged spark plugs and/or spark plug wires, by comparing digital read-outs of the spark plug voltage between cylinders on engines using conventional distributor/ignition coil, DIS (Distributor-less) or waste spark and magneto technologies.

Review: A neat little device - Great device. Great for ignition wire kilovolt testing. I also used it to verify my in-dash tachometer reading (turns out my in-dash tach is not that accurate). It's light and very easy to use, just hold it over the distributor cap and the RPMs pop up. It can also be used with distributorless systems (I believe all you need to do is to set it to 2 cycle if your engine uses a waste spark system). I needed to diagnose a vibration in an older GM car and the diagnosis required an accurate RPM reading. The SmarTach was key. I would imagine it would also be a great aid if you need to set idle speed or any kind of RPM dependent work. There are no wires to set up. It really is a smart diagnostic tool. Works with 2 to 12 cylinder engines, 2 cycle and 4 cycle.
Review: Great device - I bought this to service and tune up chainsaws. The case is tough. The unit itself is very durable. Works exactly like the demo video in the listing. Very easy to use. Turns itself off after a minute of idle time (which is good for battery life). The reset button allows you to quickly get and clear your highs for carb adjustments on two strokes. desertcart has the lowest price by a long shot. Highly recommended.

## Questions & Answers

**Q: i own a small engine repair shop will it tell if the coil is misfiring on a single or twin cylinder engine**
A: Yes, it will tell you if the out put voltage is varying. A very useful tool for a small workshop. It senses the voltage indirectly via the spark plug, or a coil lead to a distributor cap.

**Q: 1. For a car, does this work on only 1 cylinder at a time?
2. Does it have the range so it can this be used in the cockpit while test driving?**
A: 1. Only one cylinder at a time, especially if you want to use the ignition condition checking mode.2. The range can be up to about 500mm, depending on interference, on a single cylinder engine such as an outboard or a golf car. however, it needs to be a lot closer for a multi cylinder engine.

**Q: will this work to check rpm on 
small house gen?**
A: First, I bought the TA100 after an extensive search primarily to accurately check idle speed on my 2 & 4 cylinder motorcycles. It works perfectly. There is a setting for single cylinder engines so the answer is "Yes". Very well made with quality hard case.

**Q: Does it check for coil resistance output. Could it tell me if the ignition coil is good or bad?**
A: Basically it checks ignition voltages. It will tell you what voltage each spark-plug has before it fires. It will tell you what voltage the ignition coil is putting out. It will give you RPM for any size engine:- chainsaw to V8 etc, but you will need a multimeter to measure resistance. Simple faults like broken coils can be determined by simple test gear. This instrument is for the devious faults.  Mark

### ⭐⭐⭐⭐ Pricey, but a Nice Tachometer!
*by J***E on November 12, 2020*

I use this tachometer primarily for small engine (2 and 4 Cycle) testing and repair where my optical tach is impractical to use. On a few occasions, I have used it on V6 automotive engines. It worked well in all cases. Also, I have found it to be considerably more accurate than others of similar design. In fact, I returned another manufacturer's much less expensive model because of unstable, inaccurate readings. The TA100, so far, seems t be accurate and having the Peak kV feature can provide some insight when troubleshooting. The case is plastic, and unfortunately, uses a cheaper "living" hinge rather than a proper pinned hinge, and may split over time.
