Hello. I am new to scuba diving and I am looking at purchasing my first regulator. I have only been exposed to the regulators available during my training, and I havent had a chance to personally use any ScubaPro products. However, I have found good reviews on the MK-17 / S555. This package also fits my current budget. Does anybody have experience with this setup? Most of my diving will be done in Pennsylvania / Ohio in lakes and rock quarries. However I will also do some diving when on vacation in South Carolina, Florida, or the islands. Thanks for any advice.
