Frequently Asked Questions about Scubapro MK25 EVO / S620 Ti / R105

Is the regulator suitable for cold water?

Yes, the set is fully cold-water suitable. The MK25 EVO first stage with XTIS technology and CE certification according to EN250A ensures reliable operation even at very low water temperatures. For temperatures below 10°C, (e.g. local lakes at greater depths, in autumn or spring, or large lakes such as Lake Constance, the Baltic Sea, some areas of the Mediterranean, mountain lakes, etc.) we recommend a full cold water configuration with two separate first stages, such as a diaphragm-controlled, sealed first stage like the Scubapro MK17 EVO2 or the MK19 EVO.

What are the advantages of the balanced design of the first stage?

The balanced, piston-controlled construction ensures consistent air deliveryregardless of depth, cylinder pressure, or breathing rate. This allows you to enjoy a consistently low breathing resistance throughout the entire dive. Further technical information on regulators can be found, clearly explained, in our regulator lexicon.
