My brother and I completed our OW referral on Cayman Brac in 2001. Our first dive as certified divers the next morning started with dropping to a swimthrough that began around 95' (iirc) and dumped us out at 106'. You mean this isn't normal?
Here's the details. It was a boat dive and our instructor was now the DM for the 6 people on the dive. He briefed on the swimthrough and let everyone know we could skip it.
In his defence he did offer to skip it!
