A eddy current/visual plus inspection is now required every 30 months on 6351 alloy tanks per DOT reg. Luxfer however "recommends" it be done annually.
Annual VIP's for scuba tanks are a dive industry standard and not a legal requirement. Other than for 6351 alloy tanks as indicated above, a VIP is only legally required every 5 years - at the time of the hydro test per DOT reg.
I have no problem with dive shops charging for VIP's annually. I am also ok with them double checking the tank when it comes back from hydro, but since they are already making money off you for a pickup and delivery service and in some cases a marking up the cost of the hydro itself, charging you for a redundant VIP is an abusive business practice.
