OP
I’ve not used BHM before - what do they charge for a fill? The Buddy fill card is 12 air/nitrox for $100 - is it really better than that? (I’m used to paying more than that for a fill in SoCal)For a 3.5 month trip, I would buy my own tanks and use BHM for fills. If you dive regularly, you would save a ton of money over a fill card.
