I have the most recently updated 2016 core rules and the 2016 annexure in front of me. Absolutely NO mention of an electronic level - just states a SPIRIT LEVEL is allowed. All good to state it's not allowed according to the rules, another story altogether to state exactly where it says so?
And btw, there's no difference in the world between an electronic spirit level and a bubble level - you gain zero advantage using the one or the other. Unlike electronic wind instruments, that can tell precise wind direction, speed etc.
Maybe read the rules thoroughly before making these kinds of bold statements, or enlighten us as to where you see it's not allowed.
