Curious to see how many of you might have used or own one of these wireless tachometers? Here is a link to one of the ones that I am talking about: http://www.ebay.com/...=item2a2d57921e


I currently have a vibra tach but to be honest I hate using it and when trying to set max rpm I really don't want to be standing that close to the engine in case something let loose. Maybe it is the stack that makes it seem like it is running faster than what it is but I would rather just have to get close to the coil wire and get the rpm.

Actually came across another one. http://www.amazon.co..._pr_product_top

This one is a little more expensive but it will also do more than just single cylinder engines.

Here is another one that is pretty cheap but has good reviews. Might try this one since it isn't something I am going to use everyday.

That's what I use, laser tach, just put a small sticker on the crank pulley and it works.

George, I used one like the one in your first link along the way.  I borrowed it off a guy I knew, since I never needed one often enough to buy one.

 

It worked great, but I was warned to keep the battery 100% or the readings will go funky.  I don't know what that means practically, but I think the general idea was to keep it near charge all the time.
 

If worst comes to worst you can always buy one from Snap-On for a couple grand.  :mad2:

I use the reflective tape and optical type tach and they work very well as long as you have a rotating part you can get the tape onto and get a clear shot at to take a reading. I use a calibrated version at work to verify speed on centrifuges.I have no experience with an rf pickup type like the first one shown here. I think it could be subject to interferences depending on what other RF energy is coming into the antenna. The optical type will also work on any equipment, diesel, electric or whatever as you are directly measuring RPM's rather than the ignition pulse.

We use the laser type Picked it up from our local Auto parts store for 15.00 on sale, as for the reflective tape just buy a reflecrive strip for a trailer and cut it up. Red or white both work the same and you only need a small peice

Can the reflective tape be mounting  anywhere that spins ? Thinking the flywheel screen area  or front of the PTO ?

I've been using the 3 rd one the CyberTech for a couple of years. It seems to take a few moments to start reading out the speed.

Actually seems to work very well, Also you don't really need to put reflective tape on White Chalk works equally well.

That's exactly like mine & works like a million bucks!  Just stick a small 1/4" piece of reflective tape on a pulley or shaft & instant readings, and extremely accurate & responsive.

I use a wireless unit that you simply point at the spark plug wire.  It is an Echo PET 304.  I service a lot of trimmers and chainsaws and most tachs won't indicate over 9,000 RPM, but this one does.  Not an issue with a GT, but the point is that it does everything I need it to and it is about the size of a box of Tic Tacs. 

 

Here is a link that shows all the options from Echo. http://www.yamabiko-...global/?cat=269
