They're pretty similar in function. Both have bi-directional control and 'special functions', and of course do all the expected scan tool stuff... read and clear DTCs, data stream, etc. They both have 7 inch screens. Their batteries are slightly different, with the 900BT having a little more capacity. The Pro has a few more service functions at 35 versus the 28 on the 900BT, but the 900BT covers more vehicles. 

Probably the biggest difference is the Pro's DLC is cabled and the 900BT is wireless (Bluetooth), hence the "BT" in its model number. Both come with a two year subscription.
