Apeks EVX200 vs Apeks MTX-RC for UK Cold Water Diving

Comparing Apeks EVX200 vs Apeks MTX-RC for UK cold-water scuba diving. Both regulators are excellent for British conditions, but they serve different priorities. The MTX-RC is engineered for extreme cold reliability and anti-freeflow performance, making it a favourite among instructors and technical divers. The EVX200 delivers smoother breathing, improved ergonomics, and modern performance while remaining fully capable in UK waters. This guide breaks down which regulator is best for your type of diving.

UK diving places unique demands on regulators. Cold quarries, winter sea temperatures, repetitive dives, and high gas flow rates increase the risk of free-flow and performance drop-off.

This comparison focuses on real-world UK cold-water diving, not marketing specs—covering recreational, club, instructor, and technical use.

If you’re choosing between Apeks EVX200 and Apeks MTX-RC, here’s what actually matters.


Apeks EVX200 vs MTX-RC: The Big Picture Difference

  • MTX-RC = extreme cold-water reliability and anti-freeflow engineering
  • EVX200 = smoother breathing, modern design, and strong cold-water capability

Both are excellent for UK diving — they simply prioritise different performance characteristics.


Quick Decision Table

Feature Apeks EVX200 Apeks MTX-RC
Best for Comfort and performance Extreme cold reliability
UK winter diving Very good Excellent
Anti-freeflow focus High Maximum

Design Philosophy

Apeks MTX-RC Design Approach

Developed from military and extreme-environment requirements, the MTX-RC is built to keep working when conditions are at their worst.

  • Environmentally sealed first stage
  • Over-balanced design for stable airflow
  • Heavy focus on anti-freeze protection
  • Tuned conservatively to prevent free-flow

Primary intent: Reliability and stability in extreme conditions.

This is the regulator many UK instructors trust for winter quarry and training dives.

Cold-Water Performance in UK Diving Conditions

MTX-RC as a Cold-Water Specialist

This is where the MTX-RC earns its reputation.

  • Excellent resistance to ice formation
  • Performs reliably in 4–8°C water
  • Handles repetitive dives and high workloads
  • Favoured for decompression, training, and long bottom times

UK verdict: If cold water diving equipment and a regulator specifically design for preventing free-flow is your top priority, this is the safest choice.


EVX200 as a High-Performance Cold-Water Regulator

The EVX200 is fully suitable for UK conditions, but with a different emphasis.

  • Strong cold-water reliability
  • Improved thermal management compared with older designs
  • Less aggressively tuned than the MTX-RC

UK verdict: Ideal for most UK divers, but less focused on extreme-environment protection.

  • Comfortable mouthpiece reduces jaw fatigue
  • Easy-to-use controls with thick gloves

Overall feel: Premium, refined, and easy breathing.


MTX-RC Breathing Characteristics

  • Adjustable cracking resistance and venturi control
  • Can be tuned tighter for cold water use
  • Slightly firmer breathing to prioritise stability

Overall feel: Solid, dependable, and confidence-inspiring.


Durability and Ruggedness

  • MTX-RC: Built to take abuse and continue operating in harsh environments
  • EVX200: Strong construction but tuned for performance and comfort

Hose Routing and Configuration Options

EVX200 Configuration

  • Improved hose ergonomics
  • Reversible second stage
  • Well suited to single cylinder and crossover setups

MTX-RC Configuration

  • Compact forged body
  • Popular for twinset, sidemount, and technical setups
  • Clean hose routing under load

Which Regulator Should You Choose?

Choose MTX-RC if You:

  • Dive year-round in UK water
  • Instruct or follow a technical diving pathway
  • Regularly dive below 6°C
  • Want maximum anti-freeflow confidence
  • See the MTX-RC regulator setup

Choose EVX200 if You:

  • Want the smoothest breathing regulator Apeks offers
  • Mostly dive recreationally with occasional cold-water exposure
  • Value comfort and ergonomics
  • Dive primarily spring to autumn or travel internationally
  • View the EVX200 regulator package

Honest UK Verdict

Cold reliability ranking:

  1. MTX-RC
  2. EVX200

Breathing performance ranking:

  1. EVX200
  2. MTX-RC 

Most UK instructors lean toward the MTX-RC because preventing free-flow in 4°C water matters more than marginal breathing smoothness.


How This Fits Into Your Buying Decision


Final Takeaway

Both the Apeks EVX200 and MTX-RC are excellent regulators for UK diving. The decision comes down to breathing comfort versus extreme cold reliability.

If you want the smoothest breathing experience, choose the EVX200. If you want maximum confidence in the coldest UK conditions, choose the MTX-RC.
