the kids today, the new ADS divers in the Mark 3s and 4s, they have this “ZeVDeK”—Zero Visibility Detection Kit—with color-imaging sonar and low-light optics. The picture is relayed through a heads-up display right on your face bowl like a fighter plane. Throw in a pair of stereo hydrophones and you’ve got a real sensory advantage over Zack. That was not the case when I first went exo. We couldn’t see, we couldn’t hear—we couldn’t even feel if a G was trying to grab us from behind.
