As the manufacturer develops the stilts, the Pro-Jump has evolved and changes have been made to it. The following charts try to show the changes so it will be easy for you to check which version you have. All the research has been carried out by me, and there could be some errors, if you spot any let me know & I'll update it as / when I can. Also need to add a picture of the back of the footplate on one of the versions so will have that soon.
These charts may be applicable to other brands who are made by the same manufacturers but they could have had some stilts / parts in between or after which may not be on these charts.
A special thanks to all who have given me info, pictures and pointers on this.
UPDATE:
V7 model = Same as V6 but has twin D links for the knee bar straps (came in red boxes)
V8 model = Introduced in July 2009, Same as V7 but comes with a full metal lower spring foot bracket without a gap between the two bolts (new black & white box with powerbockers on)
V8+ model = Introduced in July 2009, Same as the V8 model minus the knee bar & Standard bindings but with a calf cuff and Pro-Bindings (new black & white box with powerbockers on)
