Reflections on Twenty Years of Excellence: Holding The Line
GUE Instructor Guy Shockey waxes philosophical on the role and importance of standards in the quest for diving excellent, drawing on wisdom from the world of baseball.

By Guy Shockey
Every once and a while an essay seems to write itself. It’s a welcome change from the times when collecting ideas and putting them together into some sort of cohesive whole was like pulling teeth. Recently, I happened upon an article by baseball consultant Chris Sperry. He recounted his experience listening to coach John Scolinos, who delivered one of those magical life lessons so often provided by senior coaches and wise mentors. While Scolinos was using baseball as a metaphor, I knew I could use his ideas to support something I had been thinking about for some time.
Scolinos spoke to more than 4,000 baseball coaches at the 1996 American Baseball Coaches Association convention. It was a memorable oration. Scolinos walked on stage with a baseball home plate hanging on a string around his neck. He went on to talk for 25 minutes before he finally acknowledged what everyone was wondering about. He began by asking individuals from the assembled coaches how wide a baseball home plate was. The answers were all the same: 17 inches wide.
He then asked what the major leagues did when a pitcher couldn’t throw the ball over the plate. He answered his own question and said, “they send him to Pocatello [home of minor baseball leagues]!” He told the coaches that what they didn’t do was widen the plate for the pitcher. He continued with the metaphor and applied it to other things, such as players who showed up late for practice, arrived unshaven, or who had been caught drinking. Scolinos summarized the discussion by asking, “Do we hold him accountable, or do we change the rules to fit him; in other words: do we widen home plate?”

According to Sperry, the lesson that Scolinos imparted to the coaches that day was this: “If we fail to hold ourselves to a higher standard, a standard we know to be right, and we are unwilling, or unable, to provide a consequence when they do not meet the standard…there is but one thing to look forward to, dark days ahead!” I am leaving out much of Perry’s article. I would encourage you all to read it. It speaks to accountability and maintaining a higher standard and not allowing that standard to change because it is easier or because it benefits one person.
As a Global Underwater Explorers (GUE) instructor, I am charged with making sure we don’t widen “home plate” in our GUE training. Sometimes that’s easy, but other times it’s not. There are often happy smiles, but sometimes there are disappointed faces. What there will always be, however, is a 17-inch home plate. And that is the standard we hold GUE students to in obtaining their certification.
For nearly all of us, diving is a recreational sport, but it is not without risk. Much of the diving world has been misled into believing that home plate can be whatever size we want it to be—that everything is subjective. Unfortunately, this is simply not the truth. There are objective frames of reference we can use to define whether a person is “a good diver” or not. There are factors such as precision buoyancy control, proper trim, specific propulsion techniques, and other standards that we can measure in approximately the way we can say that a baseball pitcher is a good pitcher because 90% of his pitches cross home plate. And every single one of our students and members knows this.
GUE’s reputation for excellence, which includes maintaining “home plate” at 17 inches, is what attracts those individuals who are equally attracted to excellence. They understand that there are objective measurement criteria, and they are not willing to accept anything less than being measured against excellence.
Our job as instructors, teachers, and mentors is to make sure that we not only provide our students with a frame of reference about where they are now, but that we also help them on their journey to excellence by providing guidance and direction. If we dropped someone into the middle of the desert with a map and told them to “head to Florida,” the first thing they would need to do is establish exactly where they were at on that map. Then they would locate Florida and begin their journey.
We all know that our students’ destination is excellence, so it is our job to both show them where they are and how to get to their destination. Sometimes that’s easy and sometimes it’s hard, because we don’t let them widen home plate to get there. And therein lies the reason our students feel the sense of accomplishment they do after being successful, no matter how long it took them. They knew that they arrived at their destination by crossing the same home plate as every other GUE diver. In a day and age of flexible standards, it is refreshing for all to know that the metric of measurement was not subjective, and they were “weighed, measured, and found not wanting.”
The next time you either consider GUE training or reflect on your certification, know that you will be, or you were, measured against an objective standard that was not allowed to drift or change. Your home plate is the same size today as it was 20 years ago.
You can rest assured that GUE has maintained its commitment to excellence and that your certification carries with it a legacy that is unmatched anywhere else in the diving world. This seems to me a suitable reflection on this, GUE’s 20th anniversary. I, for one, am proud to be a part of it.

Cave
The Aftermath Of Love: Don Shirley and Dave Shaw
Our young Italian poet-explorer Andrea Murdoch Alpini makes a pilgrimage to visit cave explorer Don Shirley at the legendary Bushmansgat cave in South Africa. In addition to guiding the author through the cave, Shirley and Alpini dive into history and the memories of the tragic loss in 2005 of Shirley’s dive buddy David Shaw, who died while trying to recover the body of a lost diver at 270 m/882 ft. The story features Alpini’s short documentary, “Komati Springs: The Aftermath of Love.”

South Africa, Komati Springs.
On October 28, 2004, two cave divers and long-time friends, Don Shirley and David Shaw, planned a dive at Boesmansgat (also known in English as “Bushman’s Hole”) a deep, submerged freshwater cave (or sinkhole) in the Northern Cape province of South Africa. Dave dove to 280 meters, touched the bottom and started exploring. At that time, Shaw had recently broken four records at one time: depth on a rebreather, depth in a cave on a rebreather, depth at altitude on a rebreather, and depth running a line. While on the dive at Boesmansgat, he found a body that had been there for nearly ten years, 20-year-old diver Deon Dreyer.
After obtaining permission to retrieve the body from Dreyer’s parents, the two friends returned three months later. They enrolled eight support rebreather divers (all of whom were close to Don) and Gordon Hiles, a cameraman from Cape Town, who filmed the entire process—from the preparation on the surface to the operation at the bottom of the cave. The surface marshal was Verna van Schaik, who held the women’s world record for depth at the time. Little did they know that Dave would not come back from his 333rd dive, one that he himself recorded with an underwater camera.
Researchers have determined that while attempting the retrieval, Dave ran into physical difficulties with the lines from the body bag and the wires from the light head. The physical effort of trying to free himself led to his death for what is believed to be respiratory insufficiency (see video below). Don Shirley nearly died as well, and apparently was left with permanent damage that has impaired his balance.
Nearly 20 years later, our own Andrea Murdock Alpini visits Don and has this to say:

February 2023—I arrive at the mine owned by cave expert and pioneer of deep diving, Don Shirley. The place is fantastic—the wild nature, the warm water, and the dives are amazing. Every day I spend at least 230 minutes underwater, filming the mines and what is left of man’s influence in this beautiful and God-forgotten corner of Africa. Every day I have time to talk, plan dives, and prepare the blends together with Don Shirley.
The following is a part of the story that links Don Shirley to South Africa. Stories and places intertwine between Komati Springs, Boesmansgat (or “Bushman’s Hole”) and then the fatal dive with his friend Dave Shaw.
Monkeys arrive on time every 12 hours. They showed up last night at about 5:00. They came down from the trees in large groups. They start playing, throwing themselves from one branch to another, chasing each other. Mothers hug their little ones. Some of them play with oxygen cylinders, the smaller ones instead with methane gas tanks, the ones we use for cooking. We are surrounded by gas blenders of all kinds.
A herdsman’s hat rests on the workbench. Two hands with delicate, thin skin take adapters, cylinders, and whips.They open and close taps. Notebooks report all the consumption for each charge, strictly written in liters with the utmost precision. Impressions: An Amaranth t-shirt, an unmistakable logo, that of the IANTD. A pair of jeans and then some boots. He has a slight physique, he is lean and athletic with a beard that is white now, and a few days’ old.
While he works carefully, I do not disturb him, for I know well that when mixing, one is not to be interrupted, at least this is so for anyone who loves precision. Then, when he’s done, we have time to talk a little bit together.

We sit at his desk and then go to the board to plan the dive in the mine.
Don shows me the map of the first level. He explains some important facts to me, then his hands pull out a second sheet with the plan redesigned from memory of the second level at 24 m/70 ft deep. “This is the guitar level,” he says.
At first I don’t understand. He chuckles. I look at the shape he drew and, yes, that floor plan is a cross between a Fender Stratocaster and a Picasso guitar. Anyway, it’s a guitar, no doubt.
We begin planning the dive together. It’s exciting to hear him talk; he speaks in a soft, elegant tone, and it moves me. I look at his index finger moving. I listen to his words, but I also look at his eyes.
He gives me some advice but also tells me, “This mine is more similar to a cave. I have left it as it is. I want people to explore it and not follow any lines.”
Freedom of thought, plurality of choices. Acceptance of risk, inclusion of the other in what belongs to you. It’s clear that Don’s vision of diving is uncommon. Freedom is beautiful, but it is the most dangerous thing there is, if mishandled.

The next day, we have an appointment at 7 o’clock at the lake. Before diving this morning, we saw where the “Tunnel of Love” originates on the surface, a curious gallery which I came across underwater. There are two parts of the mine that survived the destruction of the mining facility after its closure. One of these is the tunnel where we are going, the other part is perched in the middle of the mountain.
Don explains that the tunnel is now frequented by the wild animals who go to drink there, so we follow their trail. The water has flooded everything up to just a few meters below the surface of the bush. Don cuts the underbrush that makes the path difficult. He wears his faithful herdsman’s hat and never takes it off. The ground begins to tilt slightly, a good sign that we are about to arrive. A series of stones suggest that here the path has been paved. “It was covered in wood,” Don explains.
The path that started from the building where the miners lived is now demolished. Following it, we arrive at what was called “The Tunnel of Love.”
The tunnel that was the mine’s main entry point. Narrow and difficult, the tunnel led to level one—now underwater at a depth of 18 m/60 ft.
We turn on the headlamps and enter. A small colony of bats flaps its wings upon our arrival. The water touches our boots. Some roots filter from the rock and stretch to the resurgence. The scenery is evocative.

Don kneels, peering at the water, and something. He looks at the water and something changes within him. Something has changed in our shared dialogue.
It’s as if Don takes on another language as he speaks. He always looks straight ahead. His vocabulary changes, and with it his tone of voice. We talk about politics, economics, the future of Komati Springs, the origin of the name of the place, the history of the mine, but we never mention two topics: diving and Dave Shaw.
Don’s a real caveman. I know that those who love caves are not ordinary people. We who do are a little bit mad to do what we do and love, but he’s different. He is comfortable here; he has found his dimension.
I remember asking him a question when we were inside the Tunnel of Love, breaking one of the long silences: “What thoughts are going through your mind?” He seemed to have reached a meditative state, a kind of catharsis. He replied, “I am just relaxing. This is a peaceful place. “
Around nine o’clock, we travel again to the lake, leaving the dry caves behind.

The first dive lasted 135 minutes, the second 95 minutes. Once the equipment is set up, I return to the cottage to dry everything and recharge the cylinders.
Don’s hands this time are again without gloves. Before we start mixing, we walk into his office.The walls are lined with articles he has published over the years.
He shows me the medals for valor he got when he was on duty in the British Army. When we return to a small corridor that acts as a barrier, my eyes fall on two photographs. “Is that Dave?” I ask. “That’s him. We were here in Komati,” Don tells me. “You see? This is his hat,” and he points to what is on his head.

The Consequences of Love
These are the consequences of love, I think. A friendship that transcends time, life, but also death.
It’s time to prepare the blends for tomorrow. As the oxygen pumps out, Don asks me, “Have you ever seen our Boesmasgat’s diving slates?” Obviously, I had never seen the decompression tables of that famous and tragic dive to 280 m/920 ft depth at 1,600 meters (nearly 5,000 feet) altitude.
“Hang on a sec.” Don picks up a small black box with a yellow label and brings it to me. He opens it. “These are the original dive charts. These are mine; these are Dave’s.” The box also contains the famous blackboard with the inscription, (“DAVE NOT COMING BACK”) from the documentary, as well as a pair of underwater gloves used in that dive, and then the heirloom of his CCR computer that broke due to excessive hydrostatic pressure.
He exits the room. He leaves me with those emotionally charged objects in my hands. I can’t see them any differently. They obviously have historical value; but, for me, the human sense prevails. I look at the decompression tables, touch the gloves, and think about the hands that wore them, that read the various whiteboards, and I imagine the scenes of that time.


I place everything back in the box. I hand it to Don as I would hand him a precious urn. In part, it is one. I find it hard to express myself in that moment. He understands why.
At this point I ask him, “What was the true meaning of that extreme dive that Dave wanted to do? Why did he do it?”
“He just wanted to explore the bottom of that cave,” Don said. “Wherever Dave went, he wanted to get to the bottom. That’s how we’ve always done it together. So that’s what we did here at the mine.”
Don then tells me a series of details and information about that place, about the geological stratification of the cave; he talks a little about the owner of the land where the famous sinkhole is located, and finally he talks about many other aspects of their failed dive. I promised to keep it to myself, and I will do so, forever.
Such is a connection that endures over time.
