Sherwood Blizzard Pro Review: Time-Tested Reliability
Sherwood Scuba is known for making quality scuba diving equipment, and the Blizzard stay true to this heritage.
As the name implies, the Sherwood Blizzard is specifically designed for the extreme conditions of cold water diving and is considered to be one or the first regulator model specifically designed for these types of diving condition.
This Sherwood Regulator has been around for more than 30 years and is time tested for its reliability in cold water. It is no wonder why it is the preferred choice for cold water divers worldwide.
In this Sherwood Blizzard Regulator Review, we are going to look at some of the features of the newly redesigned regulator, what make it ideal cold water regulator, and what other diver’s are saying.
Newly Redesigned First Stage For Better Performance
The first stage of the Blizzard has gotten a complete makeover. Although it looks nothing like the old Blizzard, it still maintains most of the key features of the previous model but with added performance and cosmetics.
One of the most notable features is the new Tee shape design of the first stage. Sherwood claims this new design make the regulator more streamline when attached to the dive tank. This also helps reduce knock and dings during transport or while diving. balanced piston design delivers consistent intermediate pressure to the second stage at any tank pressure and depth ensuring consist breathing performance throughout the dive.
The balanced piston design delivers consistent intermediate pressure to the second stage at any tank pressure and depth ensuring consist breathing performance throughout the dive.
The first Stage also has a dry chamber (environmental seal) which protects the inner mechanisms and springs of the regulator from the harsh conditions of the cold water. It does this without using any liquids or gels. Preventing them from freezing and creating free flow. This also prevents other contaminants, like silt and sand, from entering the first stage and impeding the performance of the regulator.
Because the first stage is environmentally sealed it prevents the internal mechanisms from freezing and creating free flow. This also prevents other contaminants, like silt and sand, from entering the first stage and impeding the performance of the regulator.
It also has 2 high-pressure ports, 4 low-pressure ports, and is Nitrox compatible to 40% right out of the box.
Let’s look at the newly redesigned Second Stage
The second stage has also been completely redesigned. It is now slightly bigger in diameter with a larger diaphragm and exhaust valve for increased ease of breathing. It also now uses a balanced valve system for less breathing resistance. All these enhance make for better breathing than previous versions of the regulator.
However, it still has a heat sink as well as specially treated materials in the second stage which capture the heat from your exhalation and uses it to warm up the operating parts, preventing ice formation in colder waters. Divers also reported that it helps reduce cottonmouth (Dry Mouth) they normally experience with other regulators.
Although the reg is specifically designed for Cold Water diving it works just as good in warm water as well. So, you basically get two scuba regulator for the price of one.
What Other Diver’s Are Saying About Sherwood Blizzard
Overall the feedback on this regulator is very good, from all the reviews that I’ve read there were no reports of the regulator freezing up or free-flowing in Cold Water. Divers also say they like how the regulator perform in both cold and warm water.
However, this is a fairly new regulator so there are not a lot of reviews out there yet.
The Bottom Line
The bottom line is the Sherwood Blizzard is a time-tested cold water diving regulator. Recent upgrades in cosmetic and performance now make for more effortless breathing.
Set at a competitive price point that won’t break the bank, it makes a great alternative to more expensive cold water regulators. Although the reg is specifically designed for Cold Water diving it works just as good in warm water as well. So, you basically get two scuba regulator for the price of one.
