In both military and civilian diving communities, the default solution to any problem has become the purchase of more equipment. Manufacturers feed this belief with a constant stream of “latest and greatest” gear, each marketed as the answer to capability gaps underwater. In recreational diving, this rarely raises concern—we’ve normalized a culture where a credit card is seen as a substitute for mastery.

But in the military diving world, the stakes are very different. Mission success, operational safety, and even national security hinge on diver competence—not on how much technology they can strap to their bodies. While operators are sometimes included in procurement discussions, the more troubling reality is that neither the operators nor the command often have the operational experience or comparative knowledge needed to make informed decisions. We routinely see millions of dollars’ worth of subsea vehicles sitting unused on the deck—systems from multiple vendors that look impressive on paper, yet few operators know how to employ effectively, compare their strengths and weaknesses, or integrate them into a coherent plan for use in a contested environment. The result is a procurement landscape where equipment is acquired faster than the institution can develop the skills, understanding, and operational concepts required to actually use it. In our work training U.S. military commands and allied forces, we routinely see talented operators spending enormous amounts of time troubleshooting, configuring, and learning to manage equipment suites that—ironically—are wholly unnecessary for 90% of the real-world requirements they face.

This is a classic failure pattern: replacing training with tools.
And as we often tell students,
“Equipment should never be a substitution for a skill issue.”

The Myth of the Gear Fix

There’s an old adage:
Hand the world’s best diver the worst equipment, and he’s still a good diver. Hand the world’s worst diver the best equipment, and he’s still a bad diver.

This isn’t hyperbole. In military operations—where the definition of “best” and “worst” has real consequences—the truth becomes even clearer. High-quality baseline gear matters just as a reliable weapon matters to a ground soldier. But beyond that threshold, equipment cannot compensate for poor technique, judgment, or experience (Tuan & Amirah, 2020).

Most seasoned operators intuitively understand this. They do not rely on gimmicks or the illusion of performance gains through technology. Instead, they return—again and again—to training, fundamentals, and repetition. Without mastery of buoyancy, trim, propulsion, situational awareness, and team communication, no diver can meet mission requirements (Muhamad et al., 2023).
And there is no piece of gear that can deliver those skills.

The Training Path: No Shortcuts

Skill acquisition research is crystal clear: deliberate practice, feedback, iteration, and adaptation are the only pathways to improved physical performance (Williams & Hodges, 2023). Divers do not become proficient by simply diving more. They become proficient by practicing correctly, under informed guidance, with feedback loops that develop confidence and automaticity.

Relying on equipment to mask weaknesses produces:

• inflated confidence
• poor gas management
• fragile emergency-response capability
• ineffective buoyancy and position control

Training, on the other hand, produces transferable attributes—neural control, coordination, stress management—that are essential not just in ideal conditions but when something goes wrong at depth.

There is no special fin, no magical computer, no breakthrough rebreather that can replace the value of hundreds of correct repetitions (Hammerton, 2017).

Bruce Lee Didn’t Buy Skill, and Neither Will You

Mastery—whether in martial arts, marksmanship, or military diving—comes from work.

No martial artist can circumvent practice by ordering a “skill booster” from Amazon. No shooter reaches proficiency without thousands of correct draws from the holster. And no diver, regardless of equipment, can perform well if they lack the underlying motor patterns, control, and situational awareness that only training can deliver (Kovacs & Paulsen 2017; Pollock, 2016).

Equipment is the icing, not the cake.

The Institutional Problem: Desert Wars and Lost Knowledge

Two decades of desert-centric conflict left the U.S. military with a fractured institutional memory of maritime and subsea operations. As the strategic environment shifts back toward great-power competition—where the oceans are again central—this gap has become painfully obvious.

Into that vacuum rushed industry.
The sales pitch is predictable:

“This device solves your underwater problem.”
“This system increases your capability.”
“This technology fills your gap.”

But it doesn’t.
Only training does.

Equipment can enhance an already skilled diver.
It cannot create one.

The Path Forward: Prioritize Training, Not Technology

Research, operational history, and our own direct experience training U.S Military, Allied SOF, and federal dive elements all lead to the same conclusion:

Diver performance is far more influenced by skill, training, and experience than by equipment selection.

Procurement should reflect this reality.

Before purchasing new systems—especially those with steep learning curves or marginal mission relevance—commands must:

1. Invest in diver skill development
2. Train to a standard before scaling equipment
3. Involve operators directly in procurement decisions
4. Establish evaluation criteria rooted in operational need, not marketing claims
5. Recognize that 90% of military dive requirements demand mastery, not gadgets

Buying gear before building skill is putting failure before success.

Conclusion

As the U.S. military rebuilds maritime and subsea capability for the modern era, the path forward is unmistakably clear:

• Train divers first.
• Build capacity through skill, not tools.
• Only then select equipment that enhances, not replaces, competence.

At Archetype Undersea, we see the same pattern across commands worldwide: divers who are more capable than their equipment suggests—but whose equipment often masks the very skills they need to survive and succeed.

There is no substitute for training.
There is no shortcut to competence.
And there is no piece of equipment that can fix a skill issue.
