Great all around regulator

Got this as my first regulator along with the F8 octo. High quality regulator from Zeagle. Easy to breathe, easy to adjust, durable materials, and has worked well in warm and cold water.

Breathes like a charm

Love this regulator with how easily it breathes. Let a friend borrow it while on vacation and they didn’t want to give it back once they tried it ??

Great Regulator

It's durable, has modern features (venturi valve, air flow toggle), and breathes easily. I've seen some reviews say that the ease of breathing is incredible, and that hasn't been my experience. Don't get me wrong, it's great, but I haven't seen much difference from well maintained rental gear that I've used. Zeagle uses braided lines which I like because they bend a little easier. The reg free flowed a lot at first, even with the venturi valve set at pre-dive, but eventually calmed down after I dove with it a few times (so don't freak out). It also made a few whiny noises at first, particularly when I dove in ~50 degree water, but that also went away after being broke in. The mouth piece is very comfortable and I do not have any jaw pain or tooth displacement after diving. All in all I'm super happy with the F8 and would highly recommend it. This review should apply equally to the F8 Octo, which I also have and have the same sentiments about.

Just what the Doctor ordered...

This is the best regulator I've ever used. The sensation felt like when I think of inhale, the air flowed in effortlessly. Have not gone deep yet, or dove cold water with it, but am sure it performs. The reg is light, and not hard on the mouth. So far, this is my FAVORITE!

hard to imagine better for recreational diving

It's my first non-rental reg so of course I love it but it really is great. The flex hose doesn't pull on my 2nd stage so super comfortable, breathes super easy down to 120' (and I'm sure far beyond that). My girlfriend has an Atomic Z3 and while I haven't actually dove with it, I briefly tried breathing it while on a dive (can't remember the depth) and found the Zeagle F8 at least as good or better. Plus, the Zeagle F8 aesthetics look totally bad ass so that puts it over the top ;-).

Excellent Regulator!

I purchased this regulator with the Halo BC Bundle and it's worked amazing for me so far! I've dove with this regulator in cold water, warm water, and a couple of deep dives. It's worked flawlessly in all of them, and I never once worried about it's performance.

Very good product

Worked well in Key west. Mouth piece not too invasive or tough to hold for long periods of time. Quality materials. Blah blah blah, good product.

Love it

I excitedly opened the box. Beautiful. A nearby dive shop was having open pool night a weekacyer the reg arrived. One of the instructors showed me how to use the venturi lever and how to adjust the air flow. Into the pool I went to play with my new toy. Got it set just right. Now ready to use it on my dive in Key West and Cozumel over Christmas. aving openpool night

Good Reg

This is my first own reg. Only used rentals and this one breathes much easier.

This is an Apeks Sapphire for half the price...

Awesome matte-black look. Rugged as can be. Top-quality for bottom-of-the-barrel pricing. This is the absolute best pick for quality/price ratio, 2nd to none. This is the first time I buy Zeagle gear since I got my first Zeagle BCD about 10 years ago: forgot how high-quality their stuff is. Incredible value.

Zeagle F8 +Octo

Well worse the investment! Extremely happy with the performance in cold and warm water. I am an intermediate diver and this is like owning a Rolls Royce for me compared to what I have previously used! Extremely pleased with the flow setting and flexibility. Both Reg and Octo look sleek which is a bonus!

- Zeagle F8 DIN Regulator -
Zeagle introduces a new flagship regulator model with a completely new platform second stage design. The F8 name is derived from the well-established Zeagle Flathead series regulators. Totally new design, Zeagle's best performing regulator ever with more than 20 new improvements. Zeagle's regulators are US made, built under strict controls for quality in Zeagle's own factory, using state of the art equipment and procedures. Your regulator is one of your most important pieces of gear. No matter what kind of diving you do, you can do it better with Zeagle. The F8 is very low in profile, barely extending above the tank valve, and places the low-pressure hoses directly out to the sides, in a pattern preferred by many divers. The F8 Regulator is set for yoke valves.

The all black chrome plated marine brass first stage regulator is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

Zeagle's conical precision stainless steel high-pressure valve and advanced polymer seat provide much greater reliability and service life compared to conventional designs, while improving responsiveness and Performance at all Breathing Rates. With high performance porting in a balanced diaphragm design with dry environment seal, makes this one clean regulator first stage that will give you years of corrosion free service. The F8 Regulator has an internal structure that allows for direct airflow through the 1st stage, providing outstanding performance. First Stage is equipped with 2 high pressure (HP) 7/16" threaded ports and 5 low pressure (LP) 3/8" threaded ports for mounting of gauges and additional accessory items such as inflator Hose and octopus regulator.

Zeagle's F8 Second Stage is lightweight, compact and comfortable, with diver adjustable resistance controls, free-flow control, and built-in anti-freezing features. Specific design changes have created a regulator that is resistant to free-flow on the surface, yet has incredible smoothness and ease of breathing underwater. This pneumatically balance downstream demand valve second stage regulator is manufactured from flexible thermoplastic, thermoplastic, elastomeric, polymer and silicone rubber. The F8 Second Stage has a new case design that is smaller, lighter and molded from high impact resistant materials than its predecessor. New case snap-in insert near mouthpiece allows you to personalize your F8 for color style. New front cover design with anti-surge and ha a new stylized Z" logo regulator second stage ha a new smaller mouthpiece with super soft silicone and color accented tear resistant Bite" lugs. New exhaust valve with improved dryness and lower exhalation effort. New inhalation effort control knob for better grip and style.

What else is new! The F8 has a new threaded cover ring for improved safety and new heat sink with improved materials and greater surface area to dissipate cold. New zirconium plated inlet tube for increased corrosion resistance, new inhalation diaphragm with improved response and tear strength and a newly redesigned poppet with improved tolerances. The F8 has a patented seat saving orifice, new low pressure second stage seat and a new second stage spring made from super alloy. The Standard Hose measures 30" (76cm) and is 3/8" threaded. The complete regulator weighs approximately 2.56 lbs. (1,161 g) with the hose comes with a comprehensive owner's manual, and is Nitrox ready to 40% out of the box.

- Zeagle F8 Octopus with Hose -
Conveniently lightweight, while being designed for high performance, the Zeagle F8 Octopus with Hose is a top of the line second stage pneumatically balanced downstream demand valve second stage regulator with free flow control and built in anti-freezing features from Zeagle that offers superior comfort, ease of use, and performance, complemented by an attractive design.

The Zeagle F8 Octopus optimizes comfort utilizing a new inhalation diaphragm that provides superior tear strength and improved response time to breathing. An improved exhaust valve ensures dryness and a lower exhalation effort, while a redesigned front cover and inhalation effort control knob use co-molded components that provide the necessary grip, soft touch and ease of use. Co-molded silicone mouthpiece provides a better fit and less jaw fatigue for long term comfort. Durability and long life also have been enhanced using a seat-saving orifice, compliments of Atomic Aquatics, that retracts when not in use, extending the life of the breathing tube seat. The Zirconium-plated inlet tube and heat sink provides superior corrosion resistance, while a redesigned heat sink significantly increases surface area, aiding in the heat exchange necessary to avoid freeze-up.

The Zeagle F8 Octopus is manufactured from flexible and ridged thermoplastic, elastomeric, polymer and silicone rubber, with Buna-N O-rings and is designed to be impact resistant for durability and rugged use. It makes a for perfect combination with the Zeagle F8 regulator, and represents the standard upon which other regulators and octopuses will be judged on. Octopus comes with a 36" (91.4cm) yellow 3/8" threaded hose.
