The cons of any of the electronic ones is that the batteries will run
dead when you need it the most and can't replace the batteries (cuz you
are flying and/or just don't have batteries).
I had a discussion with my ground instructors about this issue.
Frankly spoken if you are concerned about battery lifetime I guess you
do hand prop your plane and have a signal-mirror to establish two way
communication :-)

Yes I have the slide version of the e6b with me but I have never used it
The batteries in a electronic e6b last for ever (I have the Jeppsen) and
it take me 20 sec. to replace it. (Yes I was curious and did this during
flight just to see if my instructor was right)

My only concern is the display if you have direct sunshine on it.

Maybe this is a personal thing but I need less time to use the
electronic version than to fiddle with the slide. And I need only one hand.

Just a remark: I love the old way, I have a slide rule which I use at
work and I use the slide E6B when I do my flight planning.
But during the flight I want to use the most effective and easy tool I
could get.

Maybe we should suggest to jeppsen,sporty, etc to develop a e6b with
solar cells , just to overcome the old battery story (well during night
flight you need them again):-)




The Pros: You have a piece of history in your hands
