This is one great feature of the CTX 3030, updatable. Here is a link to the firmware updates for the CTX. I downloaded the updated Exchange 2 plugged the CTX in and it prompted me to a new firmware update. Less than 10 minutes it was complete.
The best new feature is the locking pinpoint trigger. Minelab hit the nail on the head with this feature. Oh, by the way it was FREE.
