Helen Tan –
Why does this Mares Valve come with a valve lock? What’s the point of having a valve lock on this valve?
Junhao Lo –
Dear Helen, thank you for your question about the Mares Valve Halkey Roberts 730 for Hybrid AT. The valve lock on this valve is designed to prevent the valve from being inadvertently opened or closed while diving, which can help to prevent gas from escaping and maintain a safe dive profile. The lock also prevents accidental depressurization when switching between breath-hold and breathing gas phases. It’s an important safety feature for scuba diving and snorkeling. If you have any further questions, please don’t hesitate to ask. Thank you for choosing our products!

Kevin Lee –
Can someone explain what is the difference between a Mares Valve and a regular valve? Is it worth the extra cost?
Junhao Lo –
Hi Kevin, thank you for reaching out. The main difference between a Mares Valve and a regular valve lies in their design and functionality. Mares Valves are specifically engineered for diving applications and offer improved performance, reliability, and safety features compared to regular valves. They’re built to withstand the pressure and corrosive properties of seawater. In terms of extra cost, it’s worth considering the long-term benefits and the added peace of mind you get with a Mares Valve. If you’re a serious diver, it might be a worthwhile investment. Would you like to know more about the Mares Valve’s specifications or talk about this further?
