Frequently Asked Questions
ScubaPro MK25 EVO vs MK17 EVO2: which first stage should I choose?
The MK25 EVO is a balanced piston first stage — it delivers the highest airflow and instant response, and it is the choice of many performance-focused and warm-to-cold water divers. The MK17 EVO2 is a sealed diaphragm first stage — its internals are isolated from water, which makes it the traditional pick for very cold water and silty or salty conditions with less maintenance sensitivity. Both are excellent; choose the MK25 EVO for maximum performance and adjustability, the MK17 EVO2 for a fully sealed set-and-forget workhorse.
Should I order my ScubaPro regulator in DIN or yoke?
Yoke (INT) is the most common fitting on rental tanks in North America and the Caribbean, so it is the simplest choice if you mostly dive at resorts. DIN screws directly into the tank valve, is rated for higher pressures, and is standard in Europe and technical diving — and a DIN regulator can use a simple adapter on yoke tanks, which makes DIN the more flexible long-term choice for traveling divers. ScubaPro sells both versions, and a yoke regulator can later be converted to DIN by an authorized dealer using a genuine ScubaPro conversion kit (DIN owners going the other way simply use a DIN-to-yoke adapter — no conversion needed).
How often does a ScubaPro regulator need service?
ScubaPro's official recommendation is a full service by an authorized ScubaPro technician every 2 years or 100 dives, whichever comes first. If you dive heavily (100+ dives a year), ScubaPro recommends an inspection every 6 months and an overhaul annually. Staying on schedule also keeps you eligible for ScubaPro's Parts For Life program — free service parts for the original owner when the regulator is registered and purchased as part of a qualifying package from an authorized dealer. As an authorized ScubaPro dealer, we can help with registration and service when it is due.
