Scuba Pressure Gauges SPG for Recreational and Technical Regulators

Discover our selection of scuba SPG pressure gauges for recreational diving, technical configurations, DIR, sidemount, and regulator servicing.

A scuba pressure gauge is one of the most important instruments for monitoring remaining tank pressure during a dive, improving safety, gas management, and overall configuration control.

At MOMODIVE you can find:

  • Analog SPG pressure gauges
  • Dive consoles
  • Compact SPGs
  • High-visibility pressure gauges
  • Technical gauges for regulator servicing
  • Tank pressure control gauges
  • HP hoses and accessories

All compatible with the main scuba regulators and both recreational and technical diving setups.

Types of Scuba Pressure Gauges

Analog SPG Pressure Gauges

Analog scuba pressure gauges are the most common solution in recreational and technical diving.

They offer:

  • Immediate pressure reading
  • High reliability
  • Excellent underwater visibility
  • Universal compatibility

They are available in different diameters, pressure scales, and configurations.

Compact SPG Gauges

Compact pressure gauges are often used when reducing weight and bulk is important.

They are commonly used on:

  • Stage cylinders
  • Decompression cylinders
  • Light sidemount setups
  • Minimalist and travel configurations

Their compact size helps reduce the total weight on the cylinder and minimize underwater bulk.

In primary technical diving configurations, many divers instead prefer larger gauges for improved readability and precision.

High-Visibility Pressure Gauges

Higher-end gauges often use larger dials, typically:

  • 52 mm
  • 63 mm

A larger dial provides:

  • Faster underwater reading
  • Improved visibility in difficult conditions
  • More readable scale markings
  • Better reading precision

Choosing the correct pressure scale is also important:

  • A 0–300 bar gauge generally provides better readability for 232 bar cylinders
  • A 0–360 bar model is more suitable for 300 bar cylinders

A properly matched pressure scale significantly improves underwater readability.

Dive Consoles

Dive consoles combine multiple instruments into one compact unit:

  • SPG pressure gauge
  • Depth gauge
  • Diving compass

For many years consoles were the most common solution in recreational diving thanks to their ease of use and readability.

Today, many divers prefer wrist-mounted dive computers with integrated digital functions.

Digital Pressure Gauges

Digital pressure gauges use electronic displays to provide precise readings and advanced features such as:

  • Pressure alarms
  • Wireless transmission
  • Dive computer integration
  • Dive data storage

They are particularly appreciated in advanced and professional diving.

Technical Gauges for Regulator Servicing

There are also dedicated technical gauges used during scuba regulator servicing and maintenance.

These instruments allow checking:

  • First stage intermediate pressure
  • Second stage tuning and adjustment
  • HP pressure verification
  • Regulator performance during servicing and testing

These tools are mainly used by:

  • Regulator technicians
  • Service centers
  • Scuba workshops
  • Advanced technical divers

Tank Pressure Control Gauges

There are also dedicated gauges used to verify scuba cylinder pressure during:

  • Pre-dive tank checks
  • Tank filling operations
  • Gas transfer procedures
  • Technical inspections and maintenance

These instruments are widely used in both professional and technical environments to quickly check remaining cylinder pressure directly from tank valves or filling systems.

They are especially useful for:

  • Dive centers
  • Service technicians
  • Technical divers
  • Stage and decompression cylinder management
  • Travel gas pressure checks

How to choose a scuba pressure gauge

Choosing the right scuba pressure gauge mainly depends on the type of diving, the configuration used, and the desired underwater readability.

Use Recommended Gauge
Recreational diving Standard SPG or console
Technical diving High-visibility SPG
Stage / decompression cylinders Compact SPG
Sidemount Compact or technical SPG
Regulator servicing Precision technical gauge
Tank pressure control Dedicated HP pressure gauge

Comparison: Compact SPG vs Large Dial Gauge

Feature Compact SPG Large Dial Gauge
Bulk Reduced Larger
Weight Lighter Heavier
Immediate readability Good ✔ Excellent
Stage / deco cylinders ✔ Ideal Used
Main diving configurations Used ✔ Very common
Reading precision Medium ✔ Higher

FAQ – Frequently Asked Questions

What is an SPG?
SPG stands for Submersible Pressure Gauge and is used to monitor remaining tank pressure during a dive.

Compact or large pressure gauge?
It depends on the intended use. Compact SPGs are widely used on stage cylinders and lightweight setups, while larger gauges improve readability.

What is the difference between a 0–300 and a 0–360 bar gauge?
A 0–300 bar gauge generally provides a wider and easier-to-read scale for 232 bar cylinders, while 0–360 bar models are better suited for 300 bar cylinders.

Are scuba pressure gauges compatible with all regulators?
Most gauges use standard 7/16” HP connections.

Are there gauges for regulator servicing?
Yes, dedicated technical gauges are available for intermediate pressure checks and second stage tuning.

Which gauge diameter should I choose?
52 mm and 63 mm gauges generally provide easier reading compared to ultra-compact models.
