Sidemount Principles for Success by Steve Martin and Kim David is widely considered the "gold standard" for online sidemount diving education. It is an intensive, high-production-value course designed to transition divers from standard backmount or basic sidemount configurations into a refined, high-performance system. Quick Verdict

This course is best for divers who are perfectionists about their trim, buoyancy, and equipment configuration. It is not a substitute for an in-water certification course, but it is the most comprehensive technical resource available to supplement physical training. Core Course Components

The program is broken down into modular "principles" that cover every aspect of the discipline:

Equipment Mastery: Unlike generic manuals, this goes deep into the "why" behind hose routing, bolt snap placement, and wing adjustment. It focuses heavily on the XDEEP Stealth 2.0 system but applies the logic to all minimalist sidemount rigs.

The Physics of Trim: High-definition video tutorials explain how to achieve a perfectly flat profile. It uses visual overlays to show exactly where a diver's center of gravity and buoyancy should be.

Propulsion Techniques: Detailed breakdowns of the modified frog kick, helicopter turns, and back-kicking, specifically adapted for the different weight distribution of sidemount.

Cylinder Management: Step-by-step guides on "tail-out" vs. "tail-in" positioning and how to keep tanks perfectly parallel to the body throughout a dive. Strengths

Visual Clarity: The use of slow-motion underwater footage and multiple camera angles makes complex movements easy to mimic.

Verified Progression: The "Verified" aspect often refers to the structured curriculum that mirrors the actual skills required by major technical agencies like TDI, IANTD, or PADI TecRec.

Lifetime Access: The content is frequently updated to reflect new gear or refined techniques, and students retain access to these updates. Weaknesses

Equipment Bias: While the principles are universal, the course is heavily oriented toward minimalist/harness-style rigs. Divers using "hybrid" or heavy BCD-style sidemount rigs may find some sections less applicable.

High Price Point: It is a significant investment compared to standard diving books or shorter YouTube tutorials. sidemount principles for success verified

No "C-Card": Completing the online material does not give you a certification card; you still need to perform the skills in front of an instructor for an official license. Is it worth it?

Buy it if: You are struggling with "swinging tanks," poor trim, or messy hose routing and want a professional, technical solution.

Skip it if: You are a casual recreational sidemount diver who is already happy with your local instructor’s guidance and don't plan on doing technical or cave diving.

The primary "verified" principles for success in sidemount diving revolve around four foundations: buoyancy, trim, propulsion, and equipment configuration. Mastering these allows a diver to move from struggling with gear to experiencing total "freedom" underwater.

The following story illustrates these principles through the eyes of a diver transitioning from traditional back-mount to sidemount, following the curriculum of specialized guides like the Sidemount: Principles For Success eBook by Andy Davis. The Story of Leo’s Transition

Leo had been diving with a tank on his back for ten years, but as he started exploring deeper wrecks, he felt "clunky." He decided to switch to sidemount, expecting it to be an easy gear swap. He was wrong.

Day 1: The Reality CheckOn his first day of training, Leo felt like a beginner again. Instead of a single tank on his back, he had two cylinders clipped to his hips. He initially struggled with the clips and felt "out of alignment," with hoses dangling everywhere. His instructor, a specialist from a program like Sidemount Essentials, filmed his every move. When they reviewed the footage, Leo saw he wasn't horizontal; his feet were heavy, and he was "cycling" his legs to stay upright.

Applying the PrinciplesLeo began to focus on the Four Foundations:

Equipment Setup: He spent hours on land adjusting his harness and bungees so the cylinders sat tight against his body, streamlined and parallel.

Trim & Buoyancy: He practiced "dynamic trim," learning how to shift his weights and adjust his BCD to achieve a perfect horizontal hover.

Efficiency: He swapped his traditional flutter kick for a frog kick, moving efficiently without stirring up silt.

The "Success" MomentBy the sixth dive, something clicked. Leo no longer felt the weight of the tanks. He felt "one with the water," a feeling many sidemount divers describe as "nirvana". On a dive at a wreck site, he realized he could access his tank valves right in front of him, making him feel safer than ever. He was able to slip through a narrow hatch that would have been impossible with a bulky back-mount setup.

Sidemount diving is more than a gear configuration; for those who master it, it becomes a complete philosophy of underwater efficiency, comfort, and safety. Originally developed by UK sump cavers who needed to push through tight, flooded passages, the system has evolved into a mainstream preference for technical and recreational divers alike.

Achieving proficiency requires moving beyond just "clipping tanks on" and mastering the specific foundational principles for success that separate expert sidemount divers from the rest. 1. Master Your Equipment Configuration

The first foundation of sidemount success is a deep, intimate knowledge of your specific rig.

Dedicated vs. Hybrid Systems: While hybrid harnesses exist, dedicated sidemount systems are generally more streamlined, easier to set up, and provide superior stability.

Modular Valves: Ideally, use left- and right-handed modular valves. This "mirrored" setup allows valve handles to face outward and regulator first stages to face inward, protecting them from impact and streamlining hose routing.

Cylinder Selection: Choice depends on the environment. Aluminium 80s (11L) are standard for wetsuits/freshwater due to their neutral-to-positive buoyancy as they empty. Heavier steel tanks (12L) are often preferred for drysuit diving in saltwater to offset the suit’s loft. 2. Achieve Near-Perfect Stability and Trim

Stability is the hallmark of a high-level sidemount diver. It allows you to perform complex tasks or emergency drills without losing your position in the water column.

Horizontal Trim: Cylinders must sit parallel to your torso—never floating above or sinking below. This reduces drag and is critical for navigating tight spaces.

Center of Mass: Correct weighting and positioning of lead on the harness help maintain a horizontal posture without constant finning or hand movements.

Bungee Tension: Bungees should hold the cylinder valves tightly under the armpits. Self-sizing your bungees is essential, as "off-the-shelf" lengths rarely provide the exact tension needed for your torso. 3. Precision in Sidemount-Specific Skills

Once stable, you must build a systematic approach to standard operations.

Gas Management & Regulator Switching: Because sidemount uses independent cylinders, you must switch regulators at predetermined pressure increments (e.g., 30 bar or 500 psi) to keep your gas supply and cylinder buoyancy balanced. The Principle: Everything must be tucked tight to the body

Donning and Doffing: One of sidemount's greatest benefits is the ability to kit up in the water, which is ideal for rough shore entries or small boats. Success here means having a consistent process, such as always donning your primary (left) cylinder first.

Propulsion Techniques: Mastery of the frog kick, helicopter turns, and the backwards kick is essential for maintaining control and minimizing impact on the environment. 4. Verified Emergency Drills

In sidemount, your valves and regulators are directly in front of you, making it easier to identify and fix problems than with backmount. Success depends on these drills being second nature.

The S-Drill: Practice out-of-air scenarios at the start of every dive, with one diver acting as the donor and the other as the receiver.

Valve Shutdowns: Since valves are accessible under your armpits, you should be able to quickly isolate a free-flowing regulator or hose failure.

Feather Breathing: Advanced divers learn to manually operate a cylinder valve to breathe from a malfunctioning regulator. 5. Quality Training and Continuous Practice

Sidemount has a steep learning curve. Many divers struggle or give up because they attempt to teach themselves or take a course that is too short (e.g., only two days).

3. The Streamlined Profile (The "Sausage")

New sidemount divers often look like "flying squirrels"—arms and tanks flared out wide. This is the antithesis of sidemount success. The configuration is designed to fit through restrictive spaces.

  • The Principle: Everything must be tucked tight to the body. The cylinders should hang just below the armpits, and the diver’s arms should rest naturally against the tanks or chest.
  • The Success Key:
    • Bungees: The bungee system must be tensioned correctly. Too loose, and the tanks droop; too tight, and they ride up into the armpits, causing restriction and anxiety.
    • Clips: The bottom butt-plate clip must be secure to prevent the tank feet from swinging.
  • Verification: The "Doorframe Test." If you can swim through a simulated restriction (or an actual cave restriction) without your tanks or hoses snagging, your streamlining is verified.

Sidemount Principles for Success Verified: A Blueprint for the Asymmetric Diver

In the world of technical and cave diving, few equipment configurations inspire as much passion, debate, and confusion as sidemount. For every diver who claims it changed their life, there is another struggling with tank flop, first-stage entanglement, or catastrophic trim issues. The difference between these two divers isn’t luck or expensive gear; it is adherence to a set of verified principles.

The phrase "Sidemount Principles for Success Verified" is not just a marketing tagline. It represents a distillation of decades of cave exploration, instructor feedback loops, and real-world failure analysis. If you are currently frustrated with sidemount—if your tanks feel like they are trying to kill you, or if you simply want to streamline your rig—these are the seven verified pillars that guarantee success.

2. Precise Cylinder Balancing (The "See-Saw")

One of the unique challenges of sidemount is managing two independent buoyancy cells (the cylinders) alongside your personal buoyancy (the wing/BCD).

  • The Principle: You must balance the gas in your cylinders. As you breathe down your right tank, it becomes lighter. If you do not switch to your left tank, you will list (roll) to the left.
  • The Success Key: Frequent gas switches. A successful sidemount diver switches regulators every 200–300 PSI (15–20 BAR). This ensures both cylinders maintain similar buoyancy characteristics throughout the dive.
  • Verification: Look at your SPG (Submersible Pressure Gauge). If both tanks have equal pressure at the end of the dive, and you didn't have to constantly fight to stay level, your balance management is verified.

1. The Principle of Horizontal Trim (The "Hydrofoil")

The single most verified indicator of a successful sidemount diver is flat, horizontal trim. Unlike backmount, where the tank position significantly influences trim, sidemount places the diver's body entirely in control.

  • Why it matters: In sidemount, the cylinders are positioned along your sides. If you drop your legs, you create a massive surface area for drag. You effectively become a parachute.
  • The Success Key: You must achieve a flat "skydiving" position. The goal is to have your fins slightly elevated so they do not disturb the sediment (critical for cave/wreck) and to reduce drag to near zero.
  • Verification: If you can hover motionless without sculling your hands or fins, your trim is verified.

5. The Principle of Progressive Gas Management

In sidemount, your gas strategy is your navigation.

  • The Rule: Always know which tank you are breathing and which is your reserve.
  • The Standard (Open Water / Cavern): Breathe one tank down to 1/3 of its starting pressure, then switch to the other tank. Breathe the second tank down to 1/3, then return to the first tank (Rock Bottom method).
  • The Cave/Wreck Rule (Third’s): Breathe one tank down to 2/3, switch. Breathe the second down to 2/3. Now both have 1/3 left. Turn the dive.
  • Verification: At any point in the dive, you can state your current tank pressures and which tank you will switch to next, and you have sufficient gas for you and your team to exit.

2. Prioritize straightforward, repeatable rigging

  • Adopt a standardized rigging checklist and follow it every dive.
  • Secure bungees, cam bands, and butt plates consistently to maintain cylinder alignment.
  • Keep hoses routed the same way every time to avoid confusion under stress.
  • Label or color-code primary/secondary regulators and cylinder valves when appropriate.

3. Buoyancy Control

  • Trim and Buoyancy: Achieving good horizontal trim is critical. This means your body should be parallel to the seafloor or swimming surface to minimize your profile and reduce gas consumption.
  • Continuous Monitoring: Constantly monitor your buoyancy and make adjustments as necessary to maintain optimal trim and avoid touching the bottom or disturbing sediment.
