Kevin Low –
Has anyone had issues with the Mares R2 1st Stage Regulator freezing in cold water? Looking for reviews on its reliability in these conditions.
Junhao Lo –
Thank you for reaching out to us with your concern about the Mares R2 1st Stage Regulator’s performance in cold water. While we wouldn’t expect our regulators to freeze in normal use, exposure to extremely cold water for an extended period could potentially cause issues. Our regulators are built with materials that can withstand a wide range of temperatures, but prolonged exposure to temperatures below freezing can still cause components to contract and potentially freeze. However, this should not be a common occurrence during normal diving conditions. We’d like to hear more from you – can you please share more information about when and where you experienced any freezing issues with your regulator?
