How much does (my) scuba diving REALLY costs?

Hobbies are never cheap, right? 

Some hobbies costs money - some more than others. 

But I can tell you, diving is NOT cheap! But the experience -- priceless! 

Let me briefly calculate what I have spent roughly since I started diving in 2019.

Grand total? 
About RM23,250 excluding upcoming trips about RM450 with food.

And considering I have and want to go diving so much more... and get a full gear (BCD+Reg approx RM4000), and probably take up DM (RM3500)... yeah it all adds up...

So why take up diving? 

Because life is short.. if not now then when?
