Halo, Revy, Rico. All work but battery cost add up fast, Turbo doesn't use batteries.
TPI 98 with RT APP rear stock and double trigger
No Batteries Period!
Cant seem to find any.
Purchased from a website early last fall. Recieved it and had installed in 5 minutes. It doesnt take a genius to install. Just clip the air line to my responce trigger slipped in fittings on put hopper in place. Have run thru about 10 cases of paint without any problems just seems to work fine . The inner finger seems to be made of some soft forgiving rubber that aggitates the balls at just the correct spot above exit port allowing the balls to move freely downward. Also we play in some ruff terrain an the shell and lid have taken some good beating without damage. My kid brother has a spyder (newbee) basic we put on on his it also works fine.
I would recommend the Turbo loader , you save money from no batteries money saved means more money for paint.
