Thank God I have a real E6B ( no batteries required). The electronic version
on the test machine was ok but very limited.

You get to put them back in, they only remove them to clear the memory.

For certain calculations, like the flight planning questions on the IFR
written, an electronic version is really handy. The Sporty's version
only requires to to enter changed values, remembering the others as
constants. The solution is displayed alongside the input parameters,
making double checking easy.

FWIW, I brought both versions, along with several plotters, to tests.

Why? Each plotter and the metal E6B has different information and
formulae printed on it.
