Amicks has the stihl edt-9 for $69

 Now remember the 9 is faster then the 8. Here is a guy that bought the 9 review.

After using my stihl edt-9 tach for a couple weeks I feel like I can offer an opinion on it.

It's my first tach, which I got because I was tired of tuning by ear, being confidant I wasn't getting the performance I should whilst simultaneously being nervous as hell about burning up a saw.

I researched alot of tachs, but was seduced by the size and mount-ability despite an unknown refresh rate and only a few reviews. It's a lot slower than I was hoping for. Not a full 2....I would put it at 1.5 seconds just my best guess. Not quick enough. It does however offer many cool onboard mounting solutions so will prob find a home on some piece of equipment just not a saw. (Well, maybe on a csm)

Paid $80 or so including shipping from here
http://www.amickssuperstore.com/Stihl_Tach_p/stihl tach.htm


No battery change possible but with my experience with other small lithium(?) powered devices this should outlast its value and then some. its always on which i like. no forgetting to turn it off and toasted battery
see photo of back side of unit. battery permanently covered in injected molded or pressure formed plastic or epoxy of some kind. Can see battery outline. 3v lithium?

Seems robust. Is stupid simple, only one button. I spilled bar oil all over it and it still works. Bounced it around in pockets with keys pocket knives etc. Not worried about longevity.

Antenna attachment is just a loop molded in the plastic closer to the wireless receiver.
No actual plug in. For both the wireless antenna and longer wire w alligator clip, they simply thread into the holes seen in the attached pic. My most reliable results have been with the alligator clip .

See owners manual photo for operation and spark types supported. Does 3 different ignition types based on pulse number and timing: 2 pulses per 1 revolution, 1 pulse per 2 revolutions, and 1 pulse per 1 revolution.

As stated, only one button. The diagram on the directions took me a second to decipher (I'm slow) You hold the button for 3 seconds and it takes you from current RPM to max recorded RPM. If you release within 3 seconds it returns to currently reading, keeping the saved max RPM. Hold it through until the max blinks and returns to zero and you'll then start cycling thru the ignition options at 1 second intervals. You'll stay in the "ignition submenu" as long as you hold the button down. Release it when you're on the type you wish to use. Sounds incredibly difficult but in reality it becomes second nature quickly. If you can send a text message you can use this.

For my purposes it works on my traditional 2 stroke saws. Tested on MS250, MS460s and an 046. Haven't tried it on any other two stroke equipment or my 4mix stuff

So, in summary:

It's small enough to carry anywhere or mount on any piece of gasoline equipment

It's reasonably resilient (only had it 2 weeks)

It's interface is simple quick and reliable

It's finicky about placement on the saw in
antenna mode. Works better on some saws than others Alligator clips yield much better results but require removing plastic and tuning without air filter covers in place etc.

It's refresh rate is slow enough I'm replacing it for shop work. Probably with a DTI or something else at .5 sec refresh. I don't like having to WOT that long just to get a single reading, and half the time not getting one anyways bc of poor placement. This may be my fault, I'm experimenting with different ways of holding it while tuning etc. I suppose I could permanently mount wires to saws and attach the tach when using that saw but that seems like more work that a wireless tach should require

Above reasons mean it's not much use keeping in a pocket while cutting either.

Hope this was helpful for anyone considering an EDT-9

What's the refresh rate?

Faster then the 8 but still not  the .5 we  use.  Not as fast as the edt-5 TT  DTI-20K etc

Per CCC Dave  edt 7 and 8 out of production edt 9 has decent speed and works with the multi-pole flywheels.

Head to head still not as fast a refresh as the 20K


Also make sure to read in the tach thread above the feedback of a edt-9 user.

OPPAMA PET 302  Husqvarna 502711401  .5 refresh is what you want IMHO   $99 here, husky branded $149 and up

Info shared by Amick's. The OPPAMA PET-302R Tachometer is a pulse activated tachometer/hourmeter. It detects and counts electric pulses produced at the time of ignition on gasoline engines, and processes the detected signals into rpm readings according to the type of engine being monitored. This tach is capable of monitoring up to 3 different types of engines including 2 and 4 stroke engines. This tachometer comes with a 39" cable w/ clamp to connect to a plug wire for a hands free reading. Does not work on Diesel Engines.
We have been using the Oppama tach in our two cycle shop for over 20 years and we love them. The refresh rate (the amount of time the tach takes to give you the rpm) is only 0.5 seconds. Accurately measures within + or- 10 rpms. Made in Japan. Has a normal non changeable battery life of 7.5 years using 7 hours per day or 20,000 running hours.
