I looked high and low for a product that would detect spark and translate it into an RPM reading. This thing works. I've had zero issues with it picking up a signal, always using the clip lead. The unit is rubberized and feels solid. Came with a battery.You can select engine type, but I will say that you must apply some common sense logic to the readings. Some single cylinder engines fire twice per cycle and you need to manually divide the reading to get the actual RPM. This device can't know how the ignition system functions for every motor, but it is it good at picking up and counting the plug firing. Start by testing idle, since you will roughly know what that should be and then get the reading correlated to that by trying different engine settings on the menu.The reading is stable if the RPM is stable. It probably takes a 1/2 second to register, so if you think you are going to rev an engine and have it catch the peak RPM, then you are asking too much. It is meant to read RPM while the motor is being held at a steady RPM.

This inexpensive digital inductive tachometer makes setting the idle on most engines very easy. I got it to tune up my lawn mower engines, since I can't judge by ear when they are idling at the prescribed 1750 rpm. It worked fine and both mowers -- 12 hp and 14 hp Briggs and Stratton engines -- start, idle and run much better now.Note that the reading on the tach jumps around a bit on simple engines like these, say from 1725 to 1800 or so, but that's OK. Just get the idle in the ball park, set the idle mixture needle valve per the manufacturer's instructions, re-adjust the idle if needed and you're good to go. If the engine idles smoothly and accelerates cleanly to it maximum operating speed, it's almost certainly running fine.The ESI328 is a really handy tool, one that I wish I had discovered a long time ago. Highly recommended.

I operate a small engine repair shop. One of the things I have to do when tuning engines, is adjust low engine idle, and wide open throttle, on mowers and stuff. My old tach meter broke, so I had to buy this one. This is a very nice meter for the price. It has enough durability for use in a small engine shop, without having the crazy price tag you find on Fluke automotive meters. This tach meter uses an inductive pickup method for measuring RPM. You can either attach the alligator clip to directly to the sparkplug wire, or the negative sound of the engine coil. This meter also has wireless functionality, where you can just put the meter close to the sparkplug, and it will pickup the reading.This meter can read 2-cycle engines between 1 to 4 cylinders. It can also read 2-cycle engines that either fire on every revolution, or twice per revolution. It can also read 4-cycle engines between 1 to 6 cylinders. And it can read 4-cycle engines that fire once every other revolution, or once per revolution. It is very easy to set the meter for the type of engine your going to be reading from. Plus this meter comes with backlight incase your using the meter in the dark, and it oddly comes with a flashlight as well, but its pretty wimpy, so don't expect much from that.The reason I am giving this meter 4-stars, is due to accuracy issues. This meters largest problem, is not being able to give reading's within 200-MS or less. It gives reading in 750-MS. Well, 750-MS might as well be a full second, because thats what its going to feel like, while its providing readings to you. If your engine's idle is running rough, the readings will dance around all over the place. In some ways that would be considered accurate, but because it doesn't update fast enough, it comes off feeling inaccurate. Also, when revving the engine, its very slow to respond, so if your looking for an instant reading, look somewhere else, like an analog tach gauge.If you slowly increase throttle instead of reving it, the display will update fast enough to keep up, and will give you a good solid reading. Would I feel this to be accurate enough for a small engine shop? Well, considering thats what its designed for, the answer is yes. This meter however, is not accurate enough for an automotive shop. But if you operate a automotive shop, your clearly going to have the money to afford an expensive Fluke meter, so I would just go with that if your an auto tech. See video's on Youtube of this meter functioning, to help you to make a final decision. 4 out of 5 stars!

was impressed after my first use. Used on exmark zero turn. Learned that engine speed (rpm) was important to life of engine as it is an air cooled engine and it is recommended to run at 3400 rpm to cool correctly. Also at this rpm the mower will spin blades at a speed to greatly increase efficiency. First use was with the wire clip on the plug wire. I then tried using the unit wireless. Both methods gave almost identical reading. I will be using on chainsaws, string trimmers and blowers soon. Expect it to be a great help it setting carburetors on these small engine two strokes. Recommend the EZ tach plus

Arrived on time was hoping for good things at this price I am not disappointed best small engine taco I have owned good for tuning accurate and allowed me to check and tune an out board on the waterWould buy again if it goes missing

Worked exactly as described. Found the cheaper rpm testers sold online are very inaccurate. Great addition to my small engine toolbox.

Easy to use and didn't jump around on the readings too much . Great to check my ATV rpm timing on single cylinders .
