Introduction
The heart of any scuba diving setup is its regulator. Its the lifeline that provides breathable air from your tank while underwater. But just like a car needs more than an engine to run smoothly, so does a regulator need accessories to perform optimally and provide you with the best possible experience. Regulator accessories are add-ons designed to enhance performance, durability, comfort, or ease of use for dive regulators. Whether youre a beginner or a seasoned pro, investing in these small but mighty components can make a significant difference.
Types of Regulator Accessories
The world of regulator accessories is diverse and caters to various needs. Here's an overview of the most common types:
Mouthpieces
- Standard Mouthpiece: The default option that comes with most regulators, usually made from silicone or rubber. While functional, they can sometimes become uncomfortable over extended dives due to pressure on the jaw.
- Comfortable Silicone Mouthpieces: A step up from the standard mouthpiece, these are softer and designed for more comfortable use during longer dives. They often feature a slightly larger bore that allows for easier breathing.
- Octopus/Spare Air Mouthpiece: Designed to be used as an emergency backup air source (octopus) or as part of a small standalone scuba set (spare air), they are typically shorter and thicker than standard mouthpieces, making them easier to grasp while wearing thick gloves. They also have a larger bore for faster breathing.
- Purge Valves: These accessories attach to the mouthpiece and allow you to quickly clear water from your regulator without removing it from your mouth. This is especially helpful in situations where waves or currents can cause flooding.
Hose Protectors
- Mesh Hose Wraps: These are fabric wraps that protect hoses from chafing against rocks, coral, and other underwater hazards. They also provide a bit of extra insulation from the cold water.
- PVC/Rubber Hose Covers: These offer more robust protection for hoses, especially in areas with abrasive surfaces or strong currents.
- Hose Guides & Clamps: These are designed to keep hoses neatly organized and prevent tangling while diving. They can be attached to your BCD (Buoyancy Control Device) or other gear.
Hose Extensions
- Short Extensions: These short pieces of hose allow you to position your regulator closer to your mouth for better comfort, especially if you have a shorter neck.
- Longer Extensions: For divers with longer necks or those who prefer a specific regulator placement on their BCD, longer extensions can be used to achieve the desired setup.
Alternate Air Sources (Octopus)
While not strictly a regulator accessory, an octopus is a crucial piece of gear that every diver should carry. It's a secondary regulator designed for use in emergencies where your primary regulator malfunctions or runs out of air. Its important to choose an octopus with a comfortable mouthpiece and easy-to-grip design.
Regulators Weights
- Lead Weights: These weights are attached directly to the regulator body, helping to offset buoyancy issues caused by lighter regulators (often found in cold water environments).
- Trim Weights: These weights help you achieve proper trim underwater, reducing fatigue and improving hydrodynamic efficiency. They can be added to your BCD or other gear.
Regulators Lanyards
This simple accessory prevents accidental loss of your regulator if it becomes detached from your BCD. Its a small but important safety feature.
Key Features to Consider When Choosing Regulator Accessories
Before you head out and buy every shiny new gadget, here are some key features to consider:
- Material: Silicone is the most common material for mouthpieces as it's flexible, durable, and resistant to saltwater corrosion. Rubber can also be used but isnt quite as comfortable. Hose protectors often use mesh fabric or PVC/rubber materials.
- Size & Fit: Make sure any mouthpiece you choose fits comfortably in your mouth without being too tight or loose. Consider the bore size if you have difficulty breathing through a regulator a larger bore allows for easier airflow. For hose extensions, ensure they are long enough to achieve your desired positioning but not so long that they create excessive drag.
- Durability: Regulator accessories should be able to withstand repeated use and exposure to saltwater without deteriorating quickly. Look for products made from high-quality materials with reinforced seams or stitching.
- Compatibility: Always check the compatibility of regulator accessories with your existing gear before making a purchase. Different regulators have different connection points, so it's important to ensure that any new accessory will fit properly.
- Price: Regulator accessories range in price from affordable to quite expensive. While you dont need the most expensive option, investing in good quality items is always recommended for safety and longevity.
Benefits of Using Regulator Accessories
Beyond comfort, regulator accessories offer several other advantages:
- Enhanced Safety: Having a backup air source (octopus) or purge valve can be crucial in an emergency situation.
- Increased Comfort & Enjoyment: A comfortable mouthpiece and proper hose positioning can significantly improve your diving experience by reducing jaw fatigue and making breathing easier.
- Extended Regulator Lifespan: Hose protectors help prevent damage to hoses, which can lead to costly repairs or replacements down the line.
- Improved Performance: Properly trimmed gear reduces drag and improves buoyancy control, allowing you to conserve air and dive for longer periods of time.
