I am a scuba diver since about 1 1/2 year with closely 250 dives! And i am working on my DiveMASTER.
I am not perfect, or i do not know everything!
But, i think, it is not about how many dives i or others have! Or how long i am scuba diver!
I think its the ability, to see things before they happend, or to know what your buddy or Instructor needs!
i rather diving with someone who is new, than an 10 year diver with 150 dives in his log!
I did a beachdive a while ago with a friend, who invited an other diver....
the other diver show's up with tec gear on a beachdive! he dives for years, he said!
I mean nothing happend was a normal dive. But the reef is in only 20 feet of water, i mean what an paranoid idiot was that.
You guys should have seen his gear, he was ready for the Titanic!
So anyhow, if you have enough dives (minimum requ.) and you think your are confident, yes go for it! Become a Master...
