Q:The 2280-21 had a back light button, so I could see the measurements in low light conditions, but I don't see that button on the 2281-20.... nor do I see "backlight" in the product specs. Is there a backlight/Can you see the measurements in the dark on the new 2281-21? Need to know before I order one, as I use it all day every day and I need that feature. Thank you!!!! Tom H.
A:Yes, the unit has a backlight display
