The calculated tunings, imho, are slightly better. It certainly calculates faster, the battery lasts longer. Everything go faster. Down side is when back lighting is used,, which is necessary, battery life is dramatically affected. It is stronger physically because it now has a metal structure inside not plastic. It seems much stronger. The manual is useless on the extended memory as it does not even mention it even though the advertising hawks the extended memory. I like it better than my old SATIII just because of the speed and accuracy. It is pricey, but on the other hand, we know how long they last and their resale value. This is my 3rd SAT in my career.
