Thank you for your question, Natalie. The Scubapro MK25 EVO 1st Stage Regulator is an excellent choice for both recreational and technical diving. This regulator’s advanced features, such as the Extended Thermal Insulating System (XTIS), make it suitable for diving in cold water conditions. However, for technical diving, you may need to consider additional accessories, like a low-pressure gauge, high-pressure hose, or a cold-water hose. It’s also recommended to consult with a dive professional to ensure the best configuration for your specific needs. We offer a variety of packages and kits that may include the necessary accessories for technical diving.
