Need help with GTA San Andreas plz?

Hey man in this mission you do not have to use Satchel charges at all.It is for the Bet shop's robbery.You have to blow up all the ATM's with Melee weapon like Baseball bat,Knife,Br knuckles,Katana,Chainsaw,Cane etc.Although they are too feeble that you can even blow up with you punches.Hope this help.
