Got one Digital Laser Photo Tachometer to day, cost $93.00 here in Norway, Accuracy of ±(0.05%+1 digit) Sampling Time of 0.5 sec., have to test it an other day, so I can't tell you anything more about it.

Here is a link, and one pic, of almost the same model, this is a Digital Laser Tachometer, (no Photo), but I don't know the difference? other then it's at a lower cost($49.00) in US.

Did some reading in the Tach manual, and tested it on one saw today.
The difference between Laser PHOTO and non PHOTO, is that the Digital Laser PHOTO have a shorter Detecting Distance and wider Laser beam, so it's easy to use. This model have memory for last Max and Min RPM reading. There is also a symbol in the display for when the Tach is reading correctly.
I taped on some reflecting Tape to the flywheel on my muffler modded Husky 55, this saw is tuned by ear, and did some reading whit the Tach. The idle was 2770-2850 RPM, the WOT was 12750-13080 RPM. I think this Tach is easy to understand and use.

Does your manual give the min & max distance ranges for the Digital Laser Photo ?

Yor getting your Tools all wet! I haven't seen a Grey Top 55 in a long time, they look great with the Grey Top. :cool: :cool:

I can promise you that everything here is getting wet when you'r outside, cos here is a new RECORD in RAIN:censored: And the Grey Top 55 is one of the saw's I bought new in 1991, it has seen plenty wood and it's still going strong:)

Yes, for the Digital Laser Photo, the Detecting Distance is 50mm to 500mm.

Your 55 looks like BRANDNEW I have seen new chainsaws used less than 1 hour look worse than your 1991 saw! You keep a Tidy Ship. :bowdown:

Thank you, and yes, I try to have all my tools clean up and tidy after use :cool: I think it's mush better for the tools, and it's more nicer when you are taking the tools out to use again. My thinking is that the saw's or any tool should be cleaned up real good if they are to rest fore some time.

I was looking at those, but didnt want to have to put the reflective tape on all the saws to get the readings. especially when i line 4 up in a row to check in about 5 mins. Thats what scared me off that tach. But glad it worked for you.
Nice looking husky too!

I think this Tach is easy and fast to use, but as you say, you have to put on Reflective Tape on the flywheel on every saw. But if you clean it good whit Aceton before you put on the Tape, it should stay pretty good in place fore some time I think. And thank you, I think the Husky is nice too :)

I bought one those tachs for about $32 including shipping. I my case I'm not using it on saws - way to tricky to hold it and tune at the same time. I'm using it to see the speed of my lathe, drill press etc. Nice units...

Yes it tricky to hold it and tune the saw at the same time, but I tune the saw and then do some reading whit the Tach. And it seem to be at a lower cost in US, as always :laugh:
 
I just bought this tach from a small engine shop on Ebay.

I have sent a message to the seller to see if he has more available. It seems like a great unit with fast .5 sample rate, replaceable battery, max RPM readout, etc.

I'll post a follow up once I get the tach.

It was $99 shipped

EDIT: he does have more available, and as a newbie 'round here, I would love to know the appropriate way to share info for those interested.

I used the same tach for two years - worked great... RBTREE now owns it..
 
Thanks for the thumbs up Andy. :D

edit: I talked with one of the tech guys at Design Technologies, and he said the 20K is just a little faster sampling than the Fast Tach, comes with the wiring harness & the protective boot and is just as good with chain saws.

He echoed Andy's comments saying the 20K is used by many shops, including some brand name manufacurers.

He even offered to let me trade my Ebay bought 20k for a Fast Tach, but we both thought I would enjoy the 20k just fine.

It sounds like Design Technologies can be added to the list of companies with great support. :)
