Apeks XTX50 Review: A Workhorse Regulator for Serious Divers

For divers who want reliable performance without breaking the bank, the Apeks XTX50 has earned its reputation as a solid choice. This regulator appeals to instructors, technical divers, and recreational divers who need dependability across different diving conditions. It’s built to handle cold water, deep dives, and the daily abuse of dive center life.

Key Specifications

The XTX50 uses an over-balanced diaphragm first stage. It has four medium-pressure ports on a rotating turret and two high-pressure ports. The system weighs 1,269 grams with a yoke connection or 1,139 grams with DIN. Price sits around $649 USD for the complete system. The regulator comes nitrox-compatible to 40% right out of the box and can be oxygen-cleaned for higher concentrations. It’s designed for all water temperatures and features an environmental dry system that keeps water out of the main spring chamber.

Real-World Performance

Many of my customers use the XTX50, and the feedback is consistently positive. The rotating turret makes hose routing simple, which matters when you’re setting up doubles or sidemount. A colleague instructor who switched from rental gear to an XTX50 mentioned the difference was immediately noticeable on the first dive—smoother breathing and better response at depth.

The regulator breathes well in all positions. Whether you’re face-down, looking up at a wreck, or hovering vertically, the airflow stays consistent. The venturi lever and opening effort control knob are easy to adjust, even with thick gloves in cold water. The large purge button is straightforward to use.

Durability has been solid based on what we’ve seen. One divemaster working in Indonesia has been using the same XTX50 for over three years without major issues. Regular servicing keeps it running smoothly. The heat exchanger helps prevent freezing in cold water, though like any regulator, proper technique matters more than the equipment when diving in extreme conditions.

The weight doesn’t seem to bother most divers. It’s heavier than some lightweight travel regulators, but the solid build quality justifies the extra grams. The Comfo-bite mouthpiece reduces jaw fatigue on longer dives.

Cold water performance is where this regulator shines. The environmentally sealed first stage and dry chamber design prevent ice buildup. I’ve heard from technical divers using it in Great Lakes diving during winter who report reliable performance, though they’re always careful about proper surface procedures to avoid free-flows.

Comparison Context

The XTX50 competes directly with the Scubapro MK11 EVO/C370, which costs about $50 more but lacks the rotating turret. For similar money, the Scubapro system offers good performance but fewer port configuration options.

Step up to the $1,000+ range and you get the Scubapro MK25 EVO/S620 Ti or Aqualung Leg3nd Elite. These premium regulators offer titanium components and slightly better breathing performance, but the XTX50 delivers 90% of the performance at roughly half the cost. If you need the absolute best breathing characteristics, those higher-end models are worth considering. If you want excellent performance and proven reliability for less money, the XTX50 makes more sense.

The rotating turret is a practical advantage. Sidemount divers especially appreciate this feature, and it makes doubles configuration cleaner. The Scubapro MK11 EVO works fine but requires more careful hose routing.

Our Professional Opinion

The main strengths are reliability and versatility. This regulator handles warm tropical water, cold temperate diving, and everything between. The over-balanced design means breathing effort actually decreases as you go deeper, which is noticeable on dives below 30 meters. The rotating turret simplifies setup for different configurations.

The weight and bulk are the main drawbacks. It’s not the lightest regulator for travel. If you’re primarily a vacation diver flying to warm destinations, you might prefer something more compact. Service intervals are standard at annual inspections, though Apeks parts kits can sometimes be harder to source than Scubapro.

This regulator works well for instructors and divemasters who need equipment that can handle daily use in varying conditions. It’s also suitable for recreational divers advancing into technical diving or cold water environments.

Final Recommendation

Buy the XTX50 if you need a dependable regulator that performs across different diving environments. It’s a smart choice for divers who want professional-grade equipment without paying for premium features they don’t need.

This regulator suits cold water divers, technical divers setting up doubles or sidemount, and dive professionals who need reliable equipment that can handle abuse. The rotating turret makes it particularly good for divers who switch between different configurations.

Skip it if weight is your primary concern for travel, or if you’re mainly diving in warm water where a lighter, less expensive regulator would work fine. The XTX50 is built for versatility and durability, which means it carries some extra weight compared to travel-focused models.
