Zeagle F8 Regulator Review

Zeagle is not a name in diving that is synonymous with regulators while they are betterRegulatorF8GREYCutoutDIN1 copy known for their BCD’s they do produce a small line of rugged hard working regulators.  These regulators range in price from $329.95 for the Envoy 2 at their entry level, $484.95 for the Onyx 2 for the middle ground, and $629.95 for the F8 as their high end regulator.  This is going to focus on the F8 regulator from Zeagle and my experience with this lesser known regulator.

The F8 regulator is made to be rugged and able to withstand the harshest conditions. The F8 colorssimple classic design takes advantage of the classic look of regulators and the simplistic no extra bells and whistles of the first stage.  Zeagle does like to set their regulators apart by having 5 low pressure and 2 high pressure ports on their first stages, 4 of the low pressure ports are traditionally placed with the fifth facing directly forward I assume for more tech/sidemount applications.  Zeagle like other companies has adopted the usage of color kits to personalize the regulator with an assortment of colors from standard blue, and pink to purple and red.  These kits are in my opinion a little over priced but will make the regulator stand out replacing the purge cover, adjustment knob and exhaust cover.

First Stage Features:F8 first stage

  • Balanced diaphragm design and the environmentally sealed ambient chamber ensure top performance in any condition.
  • Redesigned environmental seal cap and yoke knob enhance ergonomics & design aesthetics.
  • Percision machined neoflon seat harder more reliable material, keeping you diving longer.
First Stage Materials:
Body: Brass
O-rings: Nitrile
Seat: Neoflon (PCTFE)
HP Valve: Stainless Steel

Second Stage Features:F8 second stage

  • New inhalation diaphragm provides superior tear strength and improved response time to breathing (super soft silicone molded over a low friction disk).
  • Improved exhaust valve ensures dryness and a lower exhalation effort.
  • Seat-saving orifice, compliments of Atomic Aquatics, retracts when not in use – extending the life of the breathing tube seat.
  • Seat comprised of soft silicone molded over a metal insert to deliver the firmness required for an airtight seal while maintaining the necessary elasticity to prevent leaking.
  • Redesigned front cover and inhalation effort control knob use co-molded components that provide the necessary grip, soft touch and ease of use. Available in several color kits
  • Zirconium-plated inlet tube and heat sink for superior corrosion resistance.
  • Redesigned heat sink dramatically increases surface area, aiding in the heat exchange necessary to avoid freeze-up.
  • Co-molded silicone mouthpiece for better fit and less jaw fatigue
Second Stage Materials:
Cover: TPU
Case: Nylon 12
Poppet Seat: 316 SS insert with silicone overmold
O-rings: Nitrile
Diaphragm: Elastomeric Polymer
Exhaust Valve: Silicone

My experience with the F8:
This is a very well performing regulator that I would easily put in the same running as other high end regulators.  It has a clean simple look, breaths well, and venturi switch and air flow adjustment are easy to use even when wearing heavy gloves for cold water. It is surprisingly light for the size of the second stage, I did add a swivel to my second stage for added comfort which is a strong recomendation for anyone who experiences jaw fatigue while diving.  The only issue this has presented is the lp hose for the second stage is very long much longer than I am used to for standard regulators and the addition of a swivel added an extra 2 inches to this making it at times seem a bit excessive.  Another issue that I have experienced is use of the regulator inverted can cause water to get into the second stage, by inverted i mean head down feet above the head, not lying on the back.  This being a very uncommon position only affected me while playing with students while teaching in the pool.

Over all this is a good regulator that should be considered if you are looking to upgrade, it is very hardy and reliable.  At a price of $629.95 this is one reg that should be thrown into the mix with other high end regulators like the Oceanic Zeo, Hollis 200LX, Aqualung Legend, and Scubapro MK25/S600. Zeagle may not be the brand you think of when regulators come to mind but they are a sleeper in this category with tough regs that are inexpensive to service, and can easily last a lifetime.

I hope this was helpful and feel free to share your own experience with the Zeagle F8 in the comments.

 

Zeagle Stiletto BCD Review

Zeagle is a brand that is well known for its high end equipment, especially the BCD’s.  Up until recently Zeagle has been known for BCD’s being exclusively back inflate, recently Zeagle has released their first vest inflation bcd the Halo. Most of the time when divers hear the name Zeagle they think of the Ranger, and Zena a women’s specific bcd,  but this review looks to evaluate one of the lesser known classics from Zeagle the Stiletto.

The Zeagle Stiletto is a back inflation BCD that has the Zeagle patented rip chord weight system.  Most people are more familiar with Zeagle’s ranger BCD and the Stiletto is a slimmed down version of the standard ranger, with a less heavy duty bladder.  The general Specs for the Stiletto are as follows:

Dry Weight: 7.4 lbs
Lift: 35lbIMG_3637
Weight capacity:
24lb Ripcord System
16lb Rear weight pockets

Like many of the Zeagle BCD lines the stiletto has interchangeable and replaceable parts including cummerbund, shoulders and back pad.  The double tank straps are moveable to accommodate shorter tanks and the rear weight pockets can be removed and replaced if deemed necessary.  I found these adjustable options on the Stiletto to allow me to customize a standard bcd to fit my personal preferences.

There are Two key features that in my opinion put the Zeagle line of BCD’s above others.  The first is the iconic rip chord weight system that allows for the quick release of integrated weights with a single hand pull.  Many other bcd designs use a dual pocket release system requiring the user to have both hands free to release all integrated weights.  The other unique feature for Zeagle bcd’s are the quick screw inflator with standard hose attachment.  This feature allows for the user to unscrew the bcd inflator and attach a hose in order to flush salt and grime out of the bcd bladder more easily, and replace the bcd inflator when repairs are needed.

Pros:

  • Easily adjustable parts for custom fit
  • Adequate amounts of D-rings
  • Rip chord weight systems
  • Easily replaceable inflator
  • Inflator hose attachment
  • Double tank strap
  • Removable rear weight pouches
  • Custom color options (also available for Ranger and Zena)

Cons:

  • Smaller Lift Capacity (35 lbs) Adequate for warm water diving but might not be enough for some instances of cold water diving.
  • Mesh weight Pouches (sold separately from BCD)
  • Re-lacing the weight pocket system is not intuitive

My larges problem comes down to the mesh weight pouches not being included with the BCD.  Although they are not absolutely necessary they do come in handy with using smaller increment weights mostly 1 lb weights, especially bullet weights because they can fall through the rip chord pockets without the mesh pouch.  the pouches do come in handy when carrying weights especially if you are using the same amount of weight and transporting them often.

The weight pocket system despite being very convenient and reliable, is not very intuitive when re-lacing the rip chord system.  There have been numerous encounters with divers that unfamiliar with the system laced the rip chord system improperly making the system ineffective and dangerous to use.  But because dropping ones weights is not a common occurrence so I do not see this as a big issue as long as proper instruction is given when the BCD is purchased.

Overall this is a great mid to high quality bcd compared to those on the current market.  Retail price starts around $630.

 

 

Tank You for Asking

Blue Tanks are LP Steel 72’s, Yellow tanks are AL 80’s 50’s & 65’s

Scuba tanks while a very important piece of equipment are often under appreciated.  While many divers are taught about tanks in their open water certification the role of a tank is left as the container of air.  But in many cases the choice of tank can be as important as choice of BCD or fins.  For most divers tanks are something that they might not normally think about, you travel to your destination and the shop provides tanks for you.  Some divers might be surprised to find out that there is as much variety in tanks as most other pieces of scuba equipment.

Many divers are unaware of the effects of tank choice has on our diving especially buoyancy and time.  Tanks come in a variety of sizes, the size of the take is determined by the volume of air that it is able to hold.  A common tank size is 80 cubic feet, but these sizes can vary from as small as 6 cubic feet for a backup pony bottle to as large as 149 cubic foot high pressure tank.  It is pretty obvious that the larger tanks will hold more air than the smaller if they are filled to the same pressure, but with the use of different metals and high and low pressure tanks this can also vary.  For the most part Aluminum tanks despite the size will be filled to 3000psi, steel tanks on the other hand have a fair amount of variance.  Low pressure steel tanks are exactly what they sound like they are rated for a lower pressure, depending on the tank it can range from 1800psi to 2600psi.  High pressure tanks (commonly using a DIN valve) fill on average to 3445psi, which is higher than the standard 3000psi of aluminum tanks.  What this means is that tanks that fill to higher pressure have more air packed into them than tanks that are the same size that till to a lower pressure.  So by choosing tanks that are larger and fill to a higher pressure (my favorite is HP80) you can increase your dive time compared to a smaller tank.

While size of tank might be an obvious way to increase dive time, tanks also greatly influence our buoyancy underwater.  With different choices of metal aluminum being a weaker metal and steel being a stronger metal these weights contribute to our buoyancy underwater.  Although aluminum is a lighter metal because it is weaker the walls of the tanks are much thicker.  This does usually give tanks a greater overall weight when full, when the tank is emptied the is a drastic swing in its buoyancy characteristics.  Aluminum tanks while they may vary slightly from manufacturer generally are about 4 lbs positively buoyant when empty or near empty.  This means you will be lighter at the end of the dive making it more difficult to complete a safety stop.  On the other hand while steel tanks are a stronger metal they don’t require as thick of walls and on average may be 1 lb positively buoyant to 2 lbs negatively buoyant depending on the manufacturer.  This means with a steel tank that might be 3 to 4 pounds less lead you will have to add to your weights.  The high pressure steel tanks can even be up to 4 lbs negatively buoyant when empty.

So weather or not you are buying a tank or renting a tank it is important to know how it is going to affect your dive, weather its is going to affect the duration or your buoyancy.  Be prepared to make adjustments as necessary.  If your unsure talk to the dive professionals to find out the buoyancy characteristics, and don’t forget to record in your logbook, your weights with each type of tank you use so you never have to second guess again.
