Hey there, I'm going to Da Nang in Vietnam. I have my advanced scuba cert but want to do spearfishing. I need a freediving cert right? Seems when i google "spearfishing" i dont see anything. My plan is to do it in Da Nang or in Krabi, Thailand and get my freediving cert, then just use word of mouth to find where i can do spearfishing, since it seems theres not a bunch of schools for it like scuba. Any advice? Da Nang and Krabi are my two spots i really want to be, but if yall have any reccomendations on other spots in SEA like philippines let me know please as I've always wanted to spearfish, thanks!
