When the battery is changed does it lose the time accumulated?

  • Going from memory of reading the instructions a long time ago, yes it will lose the accumulated hours time. If that’s a problem you will have to use an analog version with number wheels.

    I have one on an aircraft and it has been running for years. Unlike that one, this has a replaceable battery, which has both advantages and disadvantages. The one on the plane has only been replaced once since 2004, so it is bound to last long weather you get the batter, or battery free model. The battery is not supplied and not cheap where I live, just be aware of that. It seems easy to use, instructions are somewhat understandable. All you do is wrap it around the spark plug wire 4 times (not critical) use the supplied cable tie to secure it on the plug wire and you are ready to go. It could not be simpler.

    Small package but does a decent job. I used this unit to verify another unit I had installed on a 2-stroke hovercraft engine. The instructions for installation are easy enough, just wrap a single wire around a spark plug wire and tape it down with electrical tape. On the original installation I had to add about 3' of additional wire to reach the engine to be able to mount the tachometer up front for display. Not sure, but perhaps the additional length of wire caused a difference in readings as the installed tach read about 100 RPM less than this one. Bother were in the ballpark, so I'd say performance is acceptable. The display is a little hard to read in bright sunlight, but it can still be read. A big upside to this design would be a replaceable battery. Some reviewers said they could get the back of the case open to replace the battery. That may be possible, but on this one it is sealed up pretty tight. Still, when the time comes I may still try that. Remember to program it for your engine, for a 2-cylinder 2-cycle engine I had to select the setting for two sparks per engine revolution. Once set it seemed to work just as expected. Accuracy +/- 100 RPM or so, but generally speaking good enough.

    This little engine tachometer and hour meter works great. Like so many others have said however, the only con I can see is the lack of instructions. Due to the fact that my bulldog UTV does not have either a tachometer or hour meter, I found it necessary to purchase this to keep track of the number of hours that the engine was running for maintenance purposes and oil changes. Again as others have mentioned in their reviews the pulse sensing wire was not long enough. I did a simple in-line splice of an 20 gauge wire to add the necessary three additional feet I needed to get from the dash back to the engine compartment. I did as others had suggested and wrapped around one of the spark plug wires approximately 5 full turns of wire. The five turns in conjunction with the splice appeared to be more than enough to provide the pulsing information to the meter as everything is working exactly as it should. I am however puzzled at the two switches labeled S1 and S2. I have tried a number of times depressing either one of the other or both of the switches to see if there was a way to correctly input the fact that this engine is a four stroke twin cylinder. I tried momentarily depressing S1, nothing happened. Then depressing S2 momentarily nothing happened. Then pressing and holding S1 for several seconds then releasing with nothing happened. Then depressing S2 for several seconds and releasing with nothing happening. Then depressing and holding S1 while momentarily depressing S2 nothing happened then pressing and holding S1 well pressing and holding S2 for several seconds nothing happened then pressing and holding S2 for several seconds while momentarily pressing S1 nothing happened and finally pressing and holding S2 and pressing and holding S1 again nothing happened. Anyone else been able to figure out what if anything the switches do? I have also read that some complain about the inability to change the battery internal to the meter. On mine the back can be pried off and the battery replaced. However as cheap as these are I would simply throw the old one away and install a new one. Other than that this thing works great!

    The only thing holding these back from a 5 star review is when it's cold the unit seems to be a little temperamental. Haven't had an issue with it working the way it is supposed to when needed. But after hauling in the back of my truck from the races it doesn't seem to work till it warms up again.

    can't attest to accuracy, but does work. If anyone needs to know how to go through programming just hold down the s1 OR s2 button and keep held down until your selection you want comes up.

    Haven't used it yet but hoping it works with my motorcycle. Quality of the tachometer is just so so, the face was coming loose when I open the box but I guess for the price it's ok.

    This tach works fine for setting RPM on small engines. I don't have it mounted to anything so I can't speak for it's weather resistance or long term durability, but it is accurate at reading sparks per minute. The main drawback being that it is pretty slow to register the RPM. It takes a few seconds. It is just fine for tuning engines which is what I use it for. If you want a tach for instant readout of data, go with the much higher priced Tiny Tach which I have for my mower.
