An inaccurate tachometer can waste performance, fuel and engine life. Mechanical tachometers are notoriously inaccurate and should be checked at each annual and 100 hour inspection or any time aircraft performance is in question. The TruTach II Optical Digital Tachometer measures the true speed of your propeller from inside or outside the aircraft. Just point it at the propeller or rotor blades and TruTach II will directly display the rotational speed with a resolution of 1 RPM. No connection to aircraft systems is required and measurements may be made at any speed setting from 240 to 70000 RPM. Direct display is available for 2, 3, 4, and 5 blade propellers. Digital Signall Processing assures rock-solid display in single and multi-engine aircraft as well as helicopters. The compact 4-inch instrument weighs just 4 ounces and may be used with fast turning ultra-lights and kit plane propellers. Just turn it on, select the number of propeller blades and point. Automatic shut-off turns the unit off if you forget. The Tru Tach II includes a standard 9 volt battery providing 150 hours of operation. |

Awesome little unit. Easy to use, easy to read. Confirmed my suspicions that my tach was reading high, which is unusual. Had my prop balanced after purchasing the unit and while balancing the prop, the mechanics unit showed I was turning at 2180 when my tach showed 2300. This little unit read the same as the mechanics prop balancer. |

I didnt know what I was missing until buying this electronic tach. I have been flying our A36 Bonanza at 2320 RPM when the Beechcraft guage said 2400 RPM! This is a great addition to any propeller driven aircraft. Its accuracy is easily verified by simply pointing it to any florescent light! |
Thai A 01.08.2019 |
Good cooperation. |
David L 25.07.2019 |
Worked well for me in bright sunlight. |
Bill M 12.07.2019 |
There should be one of these in every toolbox. Easy to use and very accurate. I discovered my tach was reading 200 rpm low. |
Robert E 08.06.2019 |
High accuracy confirmed with a FAA calibrated Microvib II prop balancer. Excellent tool to confirm accuracy of mechanical and electronic techs. Also a small independent battery operated backup for your flight bag in the event of a tach failure. |
Ron 24.05.2019 |
This device works well. 4 star due to poor quality construction. Just touching the screen will cause the liquid crystal to bleed . A little more industrial robustness would make the price appropriate. |
Lynn A 19.04.2019 |
Works as advertised! |
Neil C 11.01.2019 |
Worked really well. Simple instructions straight out of the box. Easily picks up prop from inside even in overcast conditions. Turned out my tacho was way out and with my new rotax engine I could have been overreving, so this little gadget may have saved a lot of wear or worse. I will be using it as part of my 100 hourly from now on. |

Jamie 24.11.2018 |
Great little item! Loaded it up on the dash with Velcro and gave immediate readings of what I suspected was being erroneously provided by my mounted tach. 150 low! Now I have better idea of the true RPMs being generated and can better manage engine operation. Wish it worked more consistently after the sun starts to drop and the light fades, but at least I know now how my mounted tach should be interpreted. |
John H 06.11.2018 |
Works well in bright lighting if cloudy or IMC, may read LO, indicating it doesnt have appropriate light to create a reading. Lightweight and compact easy to use may need to weight or secure down depending on where you set it - it can move around a bit. Overall it does what it needs to well at a good price. |
Rocket A 11.09.2018 |
A very useful tool. |
Don 09.08.2018 |
seems to react to different light intensities and skip around a lot, would not recommend as primary instrument. |
David B 20.03.2018 |
I borrowed my mechanics. It worked great. I was able to confirm the accuracy of my mechanical panel tach. It worked through the windscreen while in flight. |
William A 16.03.2018 |
Thing works absolutely perfectly. Even in low light. AND its smart enough to turn itself off so the battery isnt dead when this boneheaded pilot forgets to turn it off. |
Dave 06.02.2018 |
Worked as advertised, quite surprising how quickly and easily it picks up the prop. I think it could have been made to have a higher quality look and/or feel. |
Dick C 01.12.2017 |
I am using as a diagnostic tool , can not freeze the reading to read at a convenient/safe time. Sensitive to lighting conditions, can not use anywhere but natural light Problem rolling large objects outside My experiences have shown this to be a poor choice. |
Thomas R 26.11.2017 |
Great addition to my PA28! Effortless set-up and installation. Popped it on top of the left side of my glare shield with adhesive backed velcro, and it provides a very accurate and easy to read RPM presentation. Great for models like mine with a 2150-2350 RPM restriction. |
Stephen B 12.10.2017 |
Excellent price on a quality tool that was shipped quickly and shipped free. - And that was to Alaska. It doesnt get much better than that. Thanks Guys. |
Dan D 05.10.2017 |
Works great. Very easy to use. |
Phil 08.09.2017 |
I wanted to check the accuracy of my electronic tach and it worked perfect. I too thought it was broken or something was not right when I powered this up in my garage with fluorescent lighting. It actually picks up the pulses of the lights at 60 cycles. Times 60 seconds . I had a reading of 3600 . Pretty cool. I now have used it with both model and homebuilt aircraft. Easy operation and I love that it uses 9v batteries as opposed to the very expensive CR series battery. |
Victor C 17.08.2017 |
Easy to use and sensitive. It has an on-off switch and a switch to select the number of blades on the propeller, 2 to 5. Calibration of the instrument can be checked using a fluorescent light. Florescent lights flicker at the frequency of the AC current 7,200 times per minute (for 60 Hz). When set to two blade propeller, the instrument should show 3,600 RPM when pointed to a fluorescent light. |
George M 20.07.2017 |
Works great! |
Matthew S 01.07.2017 |
Works great! The glare can sometimes throw it off, but minor adjustments to the angles will make it accurate again. I use this on the dash of my Mooney. I picked it up because I was nervous when my mechanical tach showed 100+ rpm over redline on takeoff. However, when using the Tru Tach and comparing them I found that I was reading ~100 RPM high on the mechanical tach and actually staying 25-30 rpm below the redline of 2700 rpm, according to the Tru Tach. |
Dan F 01.05.2017 |
A nice little tach that works quite well even when pointing at a angle. The reason for four stars is lack of TruTach support. I dropped mine and cracked the display causing it to black out. After multiple calls to the manufacturer no one ever answered the phone. I gave up and just bought another one. |
Jeff 23.02.2017 |
Works great. No need to be close to the prop. I have successfully used the TruTach II in flight through the windshield on Cessna 188 aircraft. |
Dirk P 06.09.2016 |
My performance did not meet the book values (I know, it rarely does). Bought another brand of tachometer and the readout would come and go. Returned it and purchased this one, set it to three blades, set it on the glare shield and it works perfect every time. Found my RPM was off by about 160 RPM. Great to set the power knowing the true value (still about 4 knots under the book value but close). |
Paul H 13.05.2016 |
Item works great...my tired Archer II tach was off by anywhere from 120 to 180 rpms....now I can set a power setting and get POH numbers.....especially good during long legs ..... |
Steve 06.12.2019 |
Fast delivery service from Aircraft Spruce and device works as specified. Simple to setup and use on my Arrow with easily read display. |
Will H 12.08.2019 |
Excellent product. I keep it on the glare shield as a backup. Of course I still have the factory tach and use it primarily, and the analog tach is easier for run up tests etc. but this is a great way to always know your rpm exactly. You can see the governor operate and whether itâ??s wandering. It does get hot In the sun though. Battery lasts a looong time. Even though I have it on for every flight. Donâ??t forget itâ??s optical. At dusk it gets funny until it quits altogether. Also can give some interesting readings sitting behind another plane waiting for the runway. |
Darryl K 26.07.2019 |
The tach matches my digital taçh in my plane rpm per rpm. It works great. |
Paul W 24.02.2019 |
This is the most trusted digital tach in our shop. Itâ??s the easiest and most reliable weâ??ve had yet. |
Dan S 26.04.2018 |
Works great, and canâ??t beat the price. |
Rc 29.11.2019 |
Pros: No complicated, confusing, intrusive, wiring, installation, or set up. Eliminates wasted time and money on trail and error bullshit like with many others Ive tried and returned due to erratic and inaccurate readings. Very fast, and simple installation with accurate readings. Pop in the supplied 9 volt battery, Turn it on with one of two switches, set number of blades with the other, set it on the dash facing the propeller(I used a small piece of Velcro to hold in place). Cons: Will stop reading at dusk or even dark clouds. Must have daylight. Some type of small laser light source for picking up the prop at night and a back light would be perfect and 5 stars. |
Ron 23.02.2020 |
Product worked perfect. |
J J 09.04.2020 |
Very accurate readings. Good value! |
Fred G 22.03.2020 |
This product works exactly as advertised. Very pleased. I tried a $30 optical tachometer from the internet. Total failure. Got this, checked calibration with a fluorescent bulb as instructed by mfg. It varied +/- 2 rpm (precision better than 0.001%). Got in the airplane and pointed it at the propeller. In 1-2 seconds, I got the propeller RPM. Also, very simple to change to correct number of prop blades. |
Chris R 20.04.2020 |
Could not be easier. Literally, set it on the glareshield and it begins its readout almost immediately. Confirmed our two different RPM readouts in the aircraft and now we know which one is more accurate. If you want a simple, effective means of validating prop RPM this is it. |
Eugene S 26.05.2020 |
Installed with velcro in less than 5 minutes. Works well. |
Johnny W 17.09.2020 |
Works perfect.! Also it is easy to check calibration. Just point it at a fluorescent light bulb 3600 rpms! |
Christopher O 06.10.2020 |
Mounted it on the top of my Piper 140s dash with a piece of velcro. Works great, far more accurate than the old mechanical tach and gives me a sort of heads up display. Only two negatives (not really a fault of the unit). When the setting sun is from behind, the reflection off the windshield can cause it to read double the RPM. When the ambient light drops below a certain threshold (just after sunset) it can no longer read the RPM. |
Jack 17.10.2020 |
Works perfectly, as advertised. Shall, light, simple to calibrate, and easy to read. |
Bill P 06.12.2020 |
Works very well. A good cross check of my tachometer. |
