It's not so much the rate of consumption that's the concern, but the fact that if one uses the device only rarely, there's every chance it won't work when required, and that one will then have to locate replacement batteries and insert them. This is all managable of course, but in this role a device that isn't battery powered seems preferable. Sylvia.

I would think that if your need for such a device is so infrequent that you run the risk of having flat batteries when you *do* want to use it then you don't have enough of a need to justify owning such a tool. If you *really* want to own an accurate vernier and don't want the hassle of battery problems, then hunt around on ebay for an old manual one. Non dial equipped verniers can be had for little money, however finding a metric one would be difficult if you need one. -- Regards, Noddy.

Isn't that my decision to make? Sylvia.

It certainly is, but from the sounds of it you have as much need for one as most people would have for an iron lung. -- Regards, Noddy.

Many Australians would appreciate an iron lung as it would save them the effort of breathing. And there are clearly a fair proportion whose entire mental capacity is used consumed by concentrating on breathing. You'll find them at the polling booths on the 21st, handing out how-to-vote cards for the Greens. :-) -- /"\ Bernd Felsche - Innovative Reckoning, Perth, Western Australia \ / ASCII ribbon campaign | For every complex problem there is an X against HTML mail | answer that is clear, simple, and wrong. / \ and postings | --HL Mencken |
