The Vlocity Jr. has one force mode setting, a three blade spring loaded paddle, instant auto-jam, re-programmable software and a double vision eye. When considering the Vlocity Jr., you should compare it to the standard Vlocity Select force. The Vlocity Jr. holds 180 paintballs vs. 200 in the Vlocity Select force. The Vlocity Jr. feeds paintballs at 20 balls per second vs. 25 for the Select Force version. The Vlocity Jr. has a large lid opening where you load your paintballs into the hopper. Many players prefer the Vlocity Jr. version over the Select force version. This is because the Vlocity Jr. is more compact (smaller target) and easier to load (bigger mouth). If rate of fire is a concern, the Vlocity Jr. can receive a select force upgrade chip which give it the same load speed as its bigger brother.
