All You Need to Know About The Mares Rover 2S Regulator:
Standout Features
The Mares Rover 2S may be simple, but it comes with a couple of features that improve your breathing experience underwater. The combination of Mares’ Dynamic Flow Control (DFC) in the first stage and Vortex Assisted Design (VAD) in the second stage helps the regulator deliver smoother airflow than you might expect at this price point.
Dynamic Flow Control (DFC) First Stage
The piston first stage uses Mares’ DFC system to reduce pressure drop during inhalation. In practice, that means you get a more consistent flow of air, even when you’re at depth or exerting yourself. For you, this translates into easier breathing without feeling like you have to pull hard on each breath.
Vortex Assisted Design (VAD) Second Stage
The second stage includes Mares’ VAD system, which channels air through a bypass tube to create a vortex with a low-pressure area. This helps keep the diaphragm open, making inhalation feel smoother and more natural. You’ll notice it most when you take a deep breath—airflow feels steady and unrestricted.
Sturdy Build
The second stage is made from tough technopolymer, a material that stands up to heavy use and saltwater exposure. Many dive shops use it in rental fleets because it can take repeated dives without showing much wear. For you, that means long-term durability with minimal worry.
Affordable Reliability
The Rover 2S is priced to be accessible for new divers, yet it still benefits from technology used in Mares’ higher-end models. If you want dependable performance at a cost that fits your budget, this regulator delivers.

What We Like:
✅ Affordable Price
The Rover 2S is one of the most budget-friendly regulators you can buy. If you’re starting out and don’t want to overspend, it gives you a reliable option that doesn’t drain your wallet. Many divers use it as their first regulator before moving on to more advanced setups.✅ Durable and Proven
This regulator is trusted by dive shops worldwide for rental fleets. That alone says a lot. It can handle daily use, saltwater exposure, and new divers putting it through its paces. If you want something that will hold up to years of diving, the Rover 2S is built for that.✅ VAD Second Stage
The Vortex Assisted Design makes each breath feel smoother and more natural. By keeping airflow steady, it reduces the effort you put into inhaling. That’s something you’ll notice when you take deeper breaths on a dive.✅ DFC First Stage
The Dynamic Flow Control system keeps air delivery consistent, even when you’re working harder or diving a little deeper. You don’t have to fight for air, which adds comfort and confidence underwater.✅ Easy to Maintain
With its simple piston first stage and unbalanced second stage, servicing is straightforward. Parts and service kits are available almost anywhere, making upkeep less of a hassle. That’s a big advantage if you travel or live in a place where service support can be limited.What We Don't Like:
❌ Limited Features
The Rover 2S keeps things simple, but that also means you miss out on features like adjustable inhalation or a Venturi switch. If you like fine-tuning how your regulator breathes, this isn’t the model for you.❌ Not Ideal for Cold Water
The unsealed piston design works best in warm or temperate waters. If you plan to dive in cold environments, you’ll want a regulator with environmental sealing to prevent free-flow.❌ Basic Comfort Options
While the second stage is lightweight, the mouthpiece is fairly standard. If you’re prone to jaw fatigue or want a more ergonomic design, you may need to swap out the mouthpiece for something custom.The Verdict
The Mares Rover 2S is a regulator built for divers who want reliability, simplicity, and value. It doesn’t try to compete with high-end models packed with features, but it delivers steady airflow with the help of Mares’ VAD and DFC systems. That gives you smoother, more natural breathing than you’d expect at this price point.
It’s best suited for beginner and recreational divers who mostly dive in warm water. If you want a dependable first regulator or a backup you can trust, the Rover 2S is a smart choice. Dive centers also benefit from its durability and low-maintenance design, which is why it’s found in rental fleets around the world.
If you’re looking for an affordable regulator that covers the basics well and holds up to repeated use, the Mares Rover 2S fits the bill.
