I think this is Pro version,cause we can see that is firmware B7P9.Even i buy the Pro version also show me is DW1620 and the diffrent between Pro and non Pro is outside the box,if it's Pro version outside the box will show the model as "DW1620 Pro" if non Pro just show "DW1620" and one more thing we can see is the Firmware version,if Pro version will be latest firmware like B7P9 or above,just like my Pro version it's come with Firmware B7S9 and outside box also show me it's DW1620 Pro.
Good Luck.
