sounds cool enough. I would have gotten it for myself a few years back when I had a harder time identifying pipe size. It shouldn't be limited to just those pipes if it's offering a pipe sizing guage. I mean with how often copper and pex is , it should be there too.

I love it, I hate it, I'm indifferent to it.
It does look like a useful tool, especially with my eyesight getting worse with age.

I don't get it. Though for $12.95, how can one lose? Except blown time screwing around measuring pipes sizes that you should have known/ been taught from the git.

I can use for it under water or in some mud....but I don't figure out what pipe I need until its been dug up. I told the guy I could tell from experience he said experience shouldn't be trusted?

Here is his full pitch....I left his name out
Being a second generation Irrigation Consultant with over 30+ years of experience in all aspects of Landscape & Golf Course Irrigation as well as being the former treasurer for the Northern California Chapter of A.S.I.C., I agree John with your method of sizing pipe "hydraulically." As far as sizing the O.D. of a pipe, Chad is correct, but the "String & Chart" method of sizing pipe is really a slow, time consuming, & clunky method of getting the correct nominal O.D. of a pipe.
As an irrigation professional, I have to admit that I'm embarrassed with the fact that Rain Bird, Hunter, Toro, Orbit, Sunset Books, and Ortho Books "still" recommend & push the "String & Chart" method of sizing pipe in all their literature & books when there is a "much" better & faster way to determine the nominal O.D. of a pipe or conduit using a tool we invented called the Pipe Sizer.
To give you a little background on how we came up with this invention, I was down in a 4' deep hole repairing a 3" main line when I called my Dad to order & have him drop off a 3" flex & slip coupling along with a 20' length of pipe. Well... about 2 hours later, my Dad stops by the job & drops off the 3" parts. Guess what? The main line was 2-1/2"... "not" 3". I just "knew" the main line was 3". As mentioned in Chad's post above, most "experienced" irrigation folks just "know" by looking what size a pipe is. Uh... okay. ;) I was embarrassed to admit my mistake, and this led to my Dad and I coming up with many different prototype inventions before we decided upon the final version of the Pipe Sizer. After many battles with the U.S.P.T.O., we were awarded a patent for the Pipe Sizer. We also have a tool called the Nut Sizer for sizing nuts & bolts, but that's another story. ;)
After doing extensive field testing & trials, we've determined that the Pipe Sizer is by far the quickest & most accurate method for sizing the nominal O.D. of a pipe or conduit in the field. We're still "scratching" our heads in amazement how the likes of Rain Bird and the other major irrigation manufacturers still use the "String & Chart" method in their design guides.
Take a look at our website (see below) to get a better idea on how quick and easy it is to use the Pipe Sizer tool in any possible environment whether it be under water or in a muddy hole next to other pipes in the ground. With the Pipe Sizer, only half of the pipe needs to be exposed vs. needing 360 degrees of exposed pipe for the "String & Chart" method or O.D. tape method. You can literally ID the nominal O.D. of a pipe in about 7 to 15 seconds using the Pipe Sizer vs. anywhere from 4 to 10 minutes using the "String & Chart" method or O.D. tape method.

If you want a good chuckle, watch the following videos using the "String & Chart" method and O.D. Tape method. ;)
This post isn't a sales pitch, but I do want the Irrigation Consultants & experts to know that there "is" a much better way to get the correct size O.D. of a pipe quickly & accurately saving time & money for anyone making repairs or getting field data needed for retrofit designs or determining pipe sizes for hydraulic calculations. :) The Pipe Sizer is made of rugged stainless steel, and there is an optional protective case that you can get. This tool easily fits inside a glove box, toolbox, or briefcase.
If you're interested in trying out a Pipe Sizer, send me an e-mail and mention this post. I'll make you a deal you can't refuse. ;)
If you have any questions on the Pipe Sizer, shoot me an e-mail. Thanks again for your replies...

Might be helpful, but shouldn't one be able to judge pipe sizes from 1/2 to 2 1/2 by looking at them? I suppose its helpful in the mud or whatever, we usually pump out the hole.

Include CTS size measurers and you have something

If you're dealing with pipes of that size, wouldnt you have fittings on hand to butt up to it and figure it out? without another extra tool?

as nifty as the tool looks i wonder if it measures O.D. controlled only pipe or if they have made allowance for various O.D./I.D. and wall thickness.

The tough one, when using 160 or 200 psi poly with pack joints, is both take a different size insert fitting, where the coupler is the same.

I think more in terms of copper, and maybe the ancient ABS pressure pipe that was made in CTS sizes - poly pipe not under pressure might be out of round, and not so easy to get a read on.
By now, there are enough SIDR ratings for IPS poly pipe, each with it's own set of OD's, that it wouldn't be practical to make this tool for poly pipe.
