I highly recommend IGaging EZ CAL, it has everything you need in a digital caliper,(large display, auto shut off, etc.) and does not eat batteries
Question: Does this caliper hold/retain the position reading when it's turned off? I'd guess that it does not, because that would use battery power when off, and you mentioned that it doesn't eat batteries. Couldn't find any mention of retaining the positional info on any of the manufacturer's descriptions. Not a deal breaker, but it would be useful to know. Thanks!

Yes it does, it also has auto shut off .,when you turn it back on it shows the last position it was set at.

it shows the current position it is set at.
If you measure something,let's say it is .250", then leave the caliper on the table ,it'll shut off after a couple of minutes but when you turn it back on it'll still show .250",so it shows the last measurement /position it was set at.:):):):):):):):):):):)

I think they all have to do this in order to remember where zero reference is, no? Otherwise you would have to close the jaws & re-calibrate with zero button every time before using?

I have a very nice looking electronic caliper from Clockwise Tools that has very readable (~⅝" tall) numbers on the display. Smooth operation, thumbwheel, IP54 rated. But it loses zero when you power it off. Every time you turn it on, no matter where it is or was, it initially reads zero. A bit of an irritation to have to close the jaws and re-zero. But as I'd mentioned earlier, not really a deal breaker. Love the display!

PS - another foible that seems to be related to position loss is that, unlike most electronic calipers, mine won't turn on by itself when you move the head. Makes sense. In order to keep track of position, the measuring circuitry has to continuously read the position (which may lead to battery drainage in some cheapos). Just the display is turned off. Similarly, in order to turn on when moved, the circuitry must also continuously be reading position. One goes with the other.

I have three digital callipers, two no name and one mitutoyo. One no name has auto shut off and it looses it's position. I have to close it turn power on, or turn power on close and zero. The other two do not have auto shut off, and if I turn them off, then back on they remember where they are. I put LR44 cells in them so long ago that I don't recall. I usually turn them off after use, but on occasion the one by the lathe has been on when I open the drawer to get it. I wouldn't consider any of them hard on batteries. I buy all my small cells from Dollar Tree.
