Correct. I just noticed that you had posted to him:
"I never heard of a handheld GPS with a built-in barometric altimeter."
and took the time to give you a link to examples.
Which happened to be the same link I gave to him in my post #30, to illustrate that they do exist despite the fact I had never heard of them before.
All fine but I don't think (not 100 percent on this, but fairly sure) those handhelds are legal for primary navigation anyway. Put another way, a private pilot would be ill-advised to pull one out during an FAA examination in the aircraft, under normal circumstances.
