I've never scuba'd but how do your ears not explode at 30 feet? When I've snorkled I've gone down 10-15 feet and I feel like that dude from scanners.
Yeah, touching the bottom of the 10 ft city pool was the ultimate show of little kid manliness as a kid. ears hurt at that depth.
feel pressure / pop ears / repeat
descend at a rate you are comfortable with
after the first 30ft the pressure increase isn't as bad. so once you've made it that far getting down to around 90ft is pretty easy.
going to Cozumel next week for some diving + R&R
