Precision / XR · Technical & Extended Range · Gated
This Is Where Recreational Diving Ends and Precision Begins.

Precision / XR is not a harder version of recreational diving. It is a different discipline: one that demands repeatable skill, deliberate gas planning, and genuine team awareness before the first technical dive ever happens.

What Precision / XR Builds

Precision starts with your fundamentals. Not your depth.

Every diver who has had a buoyancy problem, a navigation issue, or a moment of task-load overwhelm has already encountered the skills this pathway addresses. XR Foundations is not about going deeper. It is about making your core diving skills stable, repeatable, and reliable enough to hold up when the environment gets demanding and the task load gets real.

From there, the pathway builds progressively. Overhead-environment and rebreather pathways may follow for divers who meet the prerequisites, have the right configuration, and are approved by the instructor team. Each step requires demonstrated readiness at the previous level. Readiness is assessed before enrollment, not to gatekeep, but because arriving prepared is what makes the training work.

Before you begin

What Readiness Looks Like for Precision / XR

The assessment before XR Foundations is a conversation and an in-water evaluation, not an exam. Not every diver who is curious about XR should start with XR Foundations. Tom’s instructors are looking for specific things. Divers who arrive with these in place get more from the training. Divers who arrive without them are better served building them first.

The foundation we look for

  • Solid buoyancy and trim in recreational diving, not perfect, but stable enough to hold position under light task load
  • Reliable gas management habits: you know your SAC rate, you plan your turns, you don’t surface on reserve
  • Enriched Air Nitrox certification: gas planning is foundational to everything in the XR track
  • Diver Stress & Rescue completed or scheduled: Tom’s may require this before entering the Precision / XR track depending on course, configuration, and instructor assessment
  • Genuine interest in the discipline, not just curiosity about the gear

If any of these are missing, Tom’s instructors will map out the shortest path to get you there. The assessment conversation is the starting point, not a rejection.

Where to begin

Start Here: Three Paths Into Precision / XR

Not sure you’re ready?

Build the foundation first

Perfect Buoyancy, Navigation, Enriched Air Nitrox, and Diver Stress & Rescue are the courses that develop the skills XR Foundations will demand from the first session. They may not all be formal prerequisites for every student, but they represent the actual capability the XR track will demand.

Call for an XR readiness conversation

Tom’s instructors will talk through where you are, where you want to go, and what the path looks like. Then an in-water evaluation confirms whether XR Foundations is the right next step or whether there is something to build first.

XR Foundations is the first training step

XR Foundations is available in single backmount or sidemount configuration. For most divers, it is the entry point into the Precision / XR track and the expected foundation before further XR training at Tom’s.

Precision / XR · Step 1

XR Foundations: Currently Available

Build the precision your recreational training never demanded. Two configurations available now.

XR Foundations · Single Backmount

Your everyday setup. Held to a higher standard.

The same equipment you already dive: trained to the precision that technical diving demands. Buoyancy, trim, propulsion, and team habits refined in the configuration you know best.

View course →

XR Foundations · Sidemount

Better streamlining. Built-in redundancy. Different habits.

Sidemount changes how you move, how you manage gas, and how you position with a team. XR Foundations in sidemount builds the configuration-specific skills that make it useful rather than just different.

What comes after XR Foundations

Where XR Foundations Can Lead

Depending on instructor availability, prerequisites, configuration, and student readiness, XR Foundations may lead toward further training in some or all of the following areas. These are not entry points and not a course catalog. Talk with Tom’s before assuming any next step is available or appropriate.

  • Extended Range and decompression procedures: planned decompression dives with staged gas management
  • Technical wreck diving: progressive wreck procedures, guideline discipline, gas planning, and overhead-environment decision-making
  • Overhead-environment training: cavern, cave, wreck, or other overhead pathways only when instructor availability, location, prerequisites, and student readiness align
  • Rebreather pathways (SCR / CCR): fundamentally different life-support systems requiring separate conversation, unit-specific planning, and instructor approval
  • Gas blending: oxygen-compatible procedures, blend calculation, fill-station standards, and analysis discipline

Each of these areas has its own prerequisites, equipment requirements, instructor availability considerations, and enrollment criteria. Call Tom’s to discuss.

Why Tom’s for Precision / XR

Precision / XR Training Requires a Shop That Takes It Seriously

Precision / XR training requires more than adding courses to a catalog. It requires instructor judgment, appropriate fills, clear prerequisites, equipment planning, and a culture that prioritizes capability over certification. At Tom’s, XR training is part of the same commitment to capability over certification that applies to every course we teach.

On-site nitrox fills to EAN40

Tom’s fills nitrox on-site up to EAN40. That supports Nitrox certification, XR Foundations, and many pre-technical training needs. If a course requires additional gases, oxygen-clean protocols, staged decompression gases, or off-site blending, we will discuss those requirements before enrollment.

Multiple configurations supported

XR training may be available in single backmount, sidemount, twinset, SCR, or CCR depending on the course, instructor availability, student readiness, and equipment configuration. We will help you choose the configuration that fits your goals rather than forcing a one-size-fits-all path.

91°F pool for XR skills work

The XR Foundations skill circuit is pool-based. Our on-site 91°F pool lets students focus on trim, propulsion, buoyancy, and team procedures without cold stress becoming the main event.

In business since 1982

Tom’s has been teaching in Austin since 1982. The Precision / XR program is part of a shop with 40-plus years of investment in diver development, not a new offering added to a course catalog.

Common questions

Questions About Precision / XR

What does the assessment involve?

A conversation with a Tom’s instructor about your dive history, current skills, and goals. It is not a test with a pass or fail. It is a calibration so we can tell you honestly whether you are ready to start, what to work on first, and what the path looks like from here.

Who should consider Precision / XR vs. continuing with recreational CE?

Precision / XR is for divers who want to pursue technical diving, extended range depth, decompression diving, or sidemount as a primary configuration. If your goals are within recreational no-decompression limits and single-tank diving, the recreational CE lanes cover everything you need.

How many dives do I need before the assessment?

There is no fixed minimum. What matters more than logged dives is the quality of your buoyancy, trim, and gas management in realistic conditions. Some divers with 50 logged dives are ready. Some with 200 are not. The assessment determines this, not a number.

What equipment do I need for XR Foundations?

XR Foundations requires a back-inflation BCD (or sidemount harness), primary and backup lights, a dive computer, a surface marker buoy with reel, and a slate or wrist notebook. Tom’s can advise on specific configurations during the assessment conversation.

How long is the XR Foundations course?

XR Foundations typically runs across several sessions covering pool skill circuits and open water dives. The exact schedule depends on the configuration (single backmount or sidemount) and the student’s starting point. Tom’s instructors will outline a realistic timeline during the assessment.

Is Dive Ready required before Precision / XR?

It is strongly recommended, not technically required. Diver Stress & Rescue and Oxygen Provider are the most directly relevant. Technical diving environments have less margin for error than recreational diving, and the rescue skills in Dive Ready reflect that.
