if your ion is shooting down. its either:
1. needs a new battery (a good one not some ****ty one as whats the point saving hundreds and buying cheap batteries)
2. dwell needs upping (take the battery out when its live, put it back in and the settings should be stock. increase dwell if it still drops off)
3. the bottle or on/off arent in/on all the way and the constant air supply is not....constant
give the bolt a clean a bit of lube and it'll be running sweet. ignore the smart parts haters. its always the manufacturers fault when the user fooks up aint it???
