I have recently been using a small alarm I purchased at PC World designed for protecting laptops etc. It has a spring-loaded retracting wire that loops around the kitbag, through the trigger guard etc and locks into place with a combination. Cutting the wire sets off the loud alarm, and it can also be set to react to movement with a choice of 4 or 8 second delays. Not bad for £10. The motion detection has to be used with caution, as otherwise it goes off whenever someone accidently kicks or brushes against the old kitbag, but at least all my gear is protected whilst I am out playing. It sucks that we have to take such precautions, but this is by no means a new problem; I have seen plenty of small stuff go walkies over the last 15 years, and paintballers can be a bit "rleaxed2 as far as squeegees etc are concerned. Marker thieves, however, deserve their own special circle of hell where they are forced to listen to PBNation monkeyboys dry firing and talking about gats and noobs for all eternity.
