Ain't 20FSW the same as 20FFW?
Yes 20 feet is 20 feet but a lot of fresh water dive's are at altitude (different dive tables and weights) this is a way of specifying diving at sea level in saltwater.
Cozumel is on my bucket list. Did you do a drift dive?

No it is not the same. While it is fairly straight forward, diving at altitude does have its concerns and procedures. Usually you can figure adding approximately 4% to your actual depth for every 1000' in altitude you dive in. For instance, if your diving at 5000' then you would add 20% to your actual depth, that 60' dive would become a 72' dive with all the compression and decompression issues.
