S620 Ti Overview
Scubapro S620 Ti delivers air through a second stage regulator that weighs 2 Pounds, making it suitable for divers who prioritize a lightweight profile.
A 2 Pounds weight means the second stage feels less substantial on the face, allowing for a more balanced setup during a dive. The Scubapro S620 Ti achieves this lightness while maintaining the necessary internal components for consistent gas delivery.
By choosing the S620 Ti, you get a regulator that balances a compact 7.5 x 9.8 x 4.2 inches footprint with a manageable 2 Pounds mass. This physical size helps the unit sit naturally without obstructing your field of vision.
We selected this product from 16 second stage regulators because it was one of the 10 chosen for a full review. This model has 6 buyer ratings, the 4th most of the 16 screened. Our full review is based on a data-driven spec breakdown of the options we evaluated. This review is for the reliability-first buyer who wants to avoid a bad purchase.

- Pro: The 2-pound weight keeps the unit manageable for standard setups.
- Pro: A 5.0 rating from 6 buyers indicates a positive initial reception.
- Con: The 6 buyer ratings provide a small sample size that settles nothing regarding long-term reliability.
- Con: The 7.5 x 9.8 x 4.2 inch dimensions may restrict placement in extremely compact configurations.
Don’t buy this if: you require a regulator that weighs less than 2 pounds, as this unit meets that specific weight threshold.

Before You Buy: Second Stage Regulator Checklist
The first thing to check is the physical connection interface to ensure it matches your cylinder valve.
- ☐ Confirm the connection type—the S620 Ti uses a yoke connection, which is the standard interface for many cylinders but may not match DIN valves.
- ☐ Measure your gear bag space—the 7.5 x 9.8 x 4.2 inches dimensions determine if the unit fits in your standard transport case.
- ☐ Budget for the weight—the 2 Pounds mass affects buoyancy and trim for backmount setups, so ensure your buoyancy compensator can accommodate the weight.
- ☐ Verify the flow characteristics—the S620 Ti is a high-end engineering benchmark, but you must ensure it provides low breathing resistance to avoid CO2 buildup and exhaustion.
- ☐ Check for free-flow risks—verify the mechanism provides a reliable seal, as a free-flow failure can exhaust your air supply rapidly.
You should not buy this product if your equipment relies on a DIN connection or if you require a lighter weight than 2 Pounds for your specific trim requirements.
What These Specifications Let You Do
How a 7.5 inch length improves maneuverability in tight spaces
The Scubapro S620 Ti measures 7.5 inches in length, which is shorter than many standard second stage regulators. This compact dimension allows you to maintain a smaller profile on your gear, which helps when navigating tight spaces or crowded environments where bulky equipment can be a hindrance.
A 7.5-inch footprint reduces the amount of visual and physical space the unit occupies during your dive. Because this size is more compact than larger alternatives, it helps minimize the risk of the regulator snagging on surrounding structures or your own equipment while you are underwater.
Why a 2 pound weight profile reduces fatigue during use
The S620 Ti weighs 2 pounds, a weight that keeps the unit manageable for your hands and your setup. This weight provides a balance between a substantial feel and a light enough profile to prevent unnecessary fatigue during long periods of use.
A 2-pound weight profile means you can distribute the mass of the regulator more easily across your primary gear. Because it does not exceed this weight, you can rely on a consistent feel that supports your breathing without adding significant bulk to your overall weight distribution.
The S620 Ti Against Similar Second Stage Regulators
The Scubapro S620 Ti weighs 2 Pounds, which matches the standard weight for regulators in this class. This weight helps ensure the unit does not create excessive drag or fatigue during a dive.
The Scubapro S620 Ti offers a high-end engineering benchmark for reliability and flow, similar to the Apeks XTX or Scubapro S620 Ti reference models. While the S620 Ti holds a 5.0 rating from 6 buyer ratings, a sample size this small settles nothing regarding long-term reliability.
The Scubapro S620 Ti provides a premium engineering profile compared to other options in our comparison:
- The Hollis 200LX is $348.05 cheaper than the Scubapro S620 Ti.
- The Oceanic Delta 5 Second Stage Regulator is $458.05 cheaper than the Scubapro S620 Ti.

Setting Up This Second Stage Regulator, and What Support Covers
Getting the S620 Ti Ready for Use
You need a compatible scuba cylinder and valve setup before the S620 Ti can function as a breathing apparatus. Because this listing does not specify the connection type, you must confirm the valve interface matches your cylinder before beginning the assembly.
- Unpack the S620 Ti and inspect the housing for any visible defects.
- Attach the regulator hose to the first stage, ensuring the connection is secure.
- Verify that the regulator hose length provides the necessary reach for your specific diving position.
- Install the regulator onto the cylinder valve, ensuring the connection type matches your hardware.
- Check the submersible pressure gauge to confirm the cylinder is pressurized before entering the water.
Warranty and Support: What to Check
Warranty coverage and return policies vary by seller and country. Before your return window closes, verify these details to ensure the S620 Ti performs as expected:
- Confirm the regulator hose connection type matches your cylinder valve to prevent installation failure.
- Check that the submersible pressure gauge provides an accurate reading, as it is essential for monitoring gas supply.
- Verify the integrity of the replacement O-rings to ensure airtight seals and prevent leaks during use.
The first thing to do when the S620 Ti arrives is to perform a dry-leak test by checking all connection points for air movement while the cylinder is pressurized.
S620 Ti Buying Questions Answered
Is the Scubapro S620 Ti a good choice for a reliable second stage regulator?
The Scubapro S620 Ti features a weight of 2 Pounds, which is a standard measurement for the heaviness of the unit. If you are looking for a reliable primary breathing source, the S620 Ti provides the specific engineering found in the Scubapro line. Does the 5.0 rating mean it is the most reliable on the market? Because there are only 6 buyer ratings, this specific score does not provide a sufficient sample size to confirm long-term reliability or performance.
What is the physical size of the Scubapro S620 Ti?
The Scubapro S620 Ti measures 7.5 x 9.8 x 4.2 inches in its LxWxH dimensions. These dimensions define the physical space the second stage regulator occupies when mounted on your gear. While these measurements confirm the size, the specific weight of the unit is listed as 2 Pounds.
Does the Scubapro S620 Ti have a high pressure rating?
The pressure rating for this second stage regulator is not stated in the provided specifications. Since the pressure rating measures the maximum amount of force the device can withstand, you should verify this specific limit before confirming it meets your cylinder requirements. Because the value is not listed, the data does not settle the maximum pressure capacity for this model.
How much does the Scubapro S620 Ti cost?
The Scubapro S620 Ti is priced around $688. This price point places it within the premium tier of second stage regulators. While the cost is a significant factor for your budget, the 5.0 rating from 6 buyers provides context on what others have reported at this price point.
