Raj Singh –
This product has been a lifesaver for me. As a diving instructor, I need something reliable and efficient. The 2nd stage demand lever has exceeded my expectations in all aspects. The adjustability is perfect, and the build quality is top-notch. A bit pricey, but worth every cent.
Evelyn Wong –
Is the 2nd stage demand lever suitable for both cold and warm water diving?
Imran Hanafiah –
Thank you for your review, Evelyn. The 2nd stage demand lever on the Mares Voltrex/Beta is designed to work effectively in a wide range of water temperatures. It features a self-adjusting valve that maintains optimal air supply regardless of the diving conditions. However, the optimal performance may vary depending on specific user preferences and diving style. If you have any further questions or would like a more detailed comparison, please feel free to ask.
Ivan Lee –
I was excited to try this product, but unfortunately, it didn’t quite meet my expectations. The material feels cheap, and the adjustment mechanism feels a bit sticky at times. For the price, I expected a bit more quality.
Leah Tan –
Can I use the product with my existing first stage regulator?
Imran Hanafiah –
Thank you for your question, Leah! The Mares Voltrex/Beta Second Stage Adjustable Demand Lever is a standalone second stage regulator and can be used as an upgrade or replacement for your existing second stage. However, it is designed to work in conjunction with the Mares Voltrex First Stage Regulator or the Mares Beta First Stage Regulator. If you’re planning to use it with a different first stage regulator, please ensure it is compatible with the Mares Second Stage Regulator before making a purchase. For any further assistance, feel free to ask! Also, we’d love to hear about your experience with this product if you have any.
