Available for a limited time only, you can now upgrade your MiniDV Stabilizer Pro purchase to include a 7-12" extendable main tube for only $20 more.     Benefits With the help of the 3" extension kit included with the MiniDV Stabilizer Pro , the extendable tube increases the maximum camera weight support to 4.25 pounds. Fine tuning vertical balance is as simple as adjusting the length of the extendable tube. Thanks to the more adjustable alignment of the components, it also reduces the pressure on the main bearings, reducing friction on the panning rotation a stunning amount, giving you super smooth flying.   Offer valid on new Min iDV Stabilizer Pro purchase only.  Offer s ubject to change . 

Working our way up the camera stabilizer from the base plate, we come to the main tube.  The piece that connects everything together plays another important role.  The length of the main tube above and below the gimbal affects the vertical balance of the camera stabilizer (top to bottom).  The goal in the long run is to adjust the vertical balance so the center of gravity is just below the gimbal, so depending on the design, making adjustments to the main tube may be necessary. The basic concept is the longer you make the tube below the gimbal, the more camera weight the stabilizer will support.  Stabilizers designed for ultra light cameras may benefit from a longer tube above the gimbal depending on the design.   The million dollar question of course is how long do I make it? There of course is a whole bunch of math that you could run based on weights and measurements, but it's far easier to just experiment.  A simple starting point is the 1to1 ratio...
