Hi,DiveNav...the operation of the two units is identical. With the exception of the location of the nitrogen tissue loading bar, the displays are identical as well. If you are doing the VT3, you are essentially also doing the T3.
Again, same manufacturer, same unit...even the list price is identical. Why wouldn't you develop the "two" courses at the same time? Aeris and Oceanic are the SAME company.
we are quite familiar with Aeris/Oceanic and their products.
There are quite few graphical differences between the VT3 and the Elite T3 that would force us to capture different videos for each of them.
