Questions and Answers for ScubaPro MK25 Regulator - 1st Stage Only:

  • George:

    Sirs: I recently purchased a Sherwood SR1 Plus regulator from Ive done about 20 dives with this unit, and was quite pleased with its performance. However,this weekend on a dive in the Philippines, the 1st stage developed a serious leak from under the saddle connecting the yoke to the cylinder where the air ports are. Looks like it is going to take some time to resolve, but I am only here in the Philippines for another 2 months, and I really want to have my own regulator here (Have you ever seen Philippine rental equipment?) I cheap way for me to go might be to buy a new first stage and mate it with my Sherwood second stage. I do this already, as I use a Mares Viper Octo with my Sherwood system, and it works fine. You have some pretty good deals on Scuba Pro 1st stages &145 for a MK17 and $165 for a MK25. If these would work with my existing Sherwood SR1 second stage, that might be the best way to solve the problem in my particular circumstances. Would this work? Thanks, Ged Smith

    You might want to contact Sherwood directly to see if they have a local warranty and repair facility. If you change first stages you will need to have a service technician adjust or the first and second stages together.

SCUBAPRO is synonymous with piston-controlled first stages. Our MK25 underscores this heritage with an array of patented features and ultra-stable intermediate pressure, for an extremely punctual and consistent high delivery of air.
The MK25 balanced piston first stage is our absolute top performer, making this system our very best.
Air balanced flow-through piston provides constant and effortless air flow unaffected by changing tank pressure.
