As a boat/shore guide in a visitor destination, I'm pretty sure I can speak for my peers about the most likely regulator on the boat to free-flow; the serviced last week previously in some landlocked closet for the last 18 months reg. Even my oldest and ugliest rental reg was in the water just a few days ago and worked well enough to make a dive. ![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Percentage of dives aborted due rental reg failure vs successful rental reg dives might be less than 5%. Percentage of dives aborted due occasionally used personal reg failure vs successful occasionally used personal reg dives might be over 30%.![Shake Head :shakehead: :shakehead:](/community/styles/scubaboard/smilies/shakehead.gif)
95%. Percentage of tourist divers who had to abort first vacation dive due occasionally used personal reg failure who said, "I just got that reg serviced before I left home."![Coffee :coffee: :coffee:](/community/styles/scubaboard/smilies/coffee.gif)
