Apeks MTX-RC vs. Scubapro MK25/S600: Choose The Best Regulator for Your Next Dive

For this article we have chosen two of the biggest hitters in the diving regulator market. 

Choosing the right scuba diving regulator is crucial for a safe and enjoyable dive. These two popular options for divers who are looking for high-performance regulators are the Apeks MTX-RC and the Scubapro MK25/S600.

While both regulators offer premium quality we believe, the Apeks MTX-RC stands out as the superior choice, especially for divers who need reliability in extreme conditions.

Let's compare these two regulators and highlight why the MTX-RC is the better investment for your next underwater adventure.

First Stage Comparison: MTX-RC vs. MK25

Apeks MTX-RC First Stage:

  • Apeks Apeks MTX-RC Regulator by Oyster Diving Shop
    Military-Grade Durability: Developed in compliance with military standards for extreme cold-water performance.
  • Over-Balanced Diaphragm Design: Provides superior breathing performance at depth.
  • Environmentally Sealed: Prevents ice buildup and contamination in cold and murky waters.
  • Optimized Hose Routing: Features five low-pressure (LP) ports and two high-pressure (HP) ports for excellent configuration options.
  • Rugged Construction: Made from solid brass with a satin chrome finish for long-term durability.

Scubapro MK25 First Stage:

  • Piston-Based Design: Allows for high airflow but is not environmentally sealed, making it more susceptible to freezing in cold conditions.
  • Balanced Piston Mechanism: Provides excellent breathing resistance but lacks the over-balanced advantage of the MTX-RC.
  • Compact Design: Features a swiveling turret for flexible hose routing, but fewer protection features compared to the MTX-RC.
  • More Maintenance Required: Due to its piston design, the MK25 requires more frequent servicing, especially in harsh diving environments.

Winner: Apeks MTX-RC

Why? The MTX-RC's environmentally sealed, over-balanced diaphragm ensures better performance, especially in cold water or extreme conditions. The MK25, while offering smooth airflow, is more vulnerable to freezing and debris buildup.

Second Stage Comparison: MTX-RC vs. S600

Apeks MTX-RC Second Stage:

  • Advanced Heat Exchanger: Reduces freezing risk, making it ideal for cold-water and technical diving.
  • Venturi and Breathing Resistance Control: Customizable breathing effort for different dive conditions.
  • Tough, Lightweight Construction: Built with durable materials for rugged environments.
  • Reversible Hose Configuration: Ideal for sidemount or alternate configurations.
  • Low Work of Breathing: Effortless airflow even at depth, reducing diver fatigue.

Scubapro S600 Second Stage:

  • Adjustable Venturi & Breathing Effort: Similar to the MTX-RC but lacks extreme cold-water protection.
  • Lightweight and Compact Design: Comfortable for long dives.
  • Less Freeze-Resistant: While effective in moderate conditions, it lacks the military-grade durability of the MTX-RC.
  • Traditional Exhaust System: The exhaust design is effective but doesn’t offer the advanced heat-dissipating properties of the MTX-RC.

Winner: Apeks MTX-RC

Why? The MTX-RC is better suited for demanding conditions, including technical, wreck, and cold-water diving. The S600 performs well in warm waters but lacks the same durability and freeze-resistant design.

Overall Verdict: Why the Apeks MTX-RC is the Better Choice

While the Scubapro MK25/S600 is a popular choice among recreational divers, it falls short when it comes to extreme conditions and long-term reliability. The Apeks MTX-RC is simply the better choice for divers who demand superior performance, durability, and versatility.

Key Reasons to Choose the Apeks MTX-RC:

Better for Cold Water & Technical Diving – The MTX-RC is built to perform in freezing temperatures, unlike the MK25/S600.

 Lower Maintenance & Higher Durability – Environmentally sealed design means fewer servicing requirements.

More Hose Routing Options – Ideal for both recreational and technical divers.

Proven Military-Grade Performance – Designed to withstand extreme environments.

For divers who want reliability, safety, and superior performance, the Apeks MTX-RC is the clear winner.
