The "Sporty's" one is just an ASA model. The old CX1.
Only reason I know this, is someone left one in our lost and found for a couple of years. Never picked it up. Was going to get tossed since it wasn't working, and I cleaned it up, and the battery connections. Learned to use it, and read the online docs from the ASA site.
Then, about a week or two later, one of my students came in with the flat Sporty's model. The interface is exactly the same. Buttons are in a different place on the sporty's model, and they have 4 way arrows rather than two, but the screen is the same layout, and function.
It is much faster to fill in a flight planning form, with the digital one. Conversions it does are pretty cool. Does the Hour:Minute:Second to hours.tenths conversion. So when you have a a 13.5 minute leg, and you are trying to figure fuel burn, it is a little easier to read, than trying to guess what line the circular slide rule points to. But then, I always just round up on stuff like that on the e6b for safety.
I wouldn't pay the amount charged for them by these companies, but since I got what was like a $60 tool for free, I'm happy to see it does work well in some situations. It stays in my flight bag, but I have yet to try and use it to punch in the buttons in flight.
It would be much easier to figure something at any time with, since you are always prompted for the next thing. You can add inline for each requested entry. And answers that apply, carry over automatically for the next calculation you want to do, and are autoentered. Also, changing one thing, like a speed, is a matter of hitting enter a few times, and the previous entries will autofill each time, and you just type in the new number in the one place it is needed.
