What Is The Difference Between The SP And The SP PRO?

In terms of stabilization performance and build quality both the SP and SP-PRO are on par with one another.

Here are some features the SP-PRO has that the SP does not:

1. SP PRO has wireless bluetooth capability which allows it to be controlled with our smartphone app and wireless remote. The smartphone apps enables you to control camera functions like zoom, direction of way lens is facing you, shutter, etc all using the handle of the gimbal.
2. The SP PRO can be charged through the USB port. The battery does not need to be removed for charging and requires only one battery instead of two. 
3. The SP PRO has upgraded motors and encoders making it quicker to respond.
