PART 1
Before purchasing the Fourth Element Ellipse system, I searched for reviews on the internet but could pretty much only find ad copy. So in an effort to be un-jaded and independent I purchased a couple of sets (one set for me and one set for my wife) so that we could test and offer an honest review.
Some background on us:
I have an Aqualung Fusion Bullet drysuit that had Si-Tech QCS oval wrist cuffs pre-installed. I dive all year round in the quarries and lakes in Belgium. The temperature of the waters here range from 21c in the late summer to 2c in late winter.
My wife has a custom Teknodivers drysuit. She purchased it with the QCS oval wrist cuff system and the Si-Tech Virgo system pre-installed. She wanted something with a lower profile.
My wife and I have experience diving the following systems:
Si-Tech Glove Lock
Si-Tech Virgo
Waterproof Ultima DGS
Fourth Element Ellipse
Additionally, I regularly dive with people who use:
Northern Divers
Rolock
Kubi
General info about the Ellipse system
Fourth Element designed the Ellipse system in conjunction with Si-Tech to make/market a low profile dryglove system designed to directly integrate with Si-Tech’s QCS oval system AND retain the systems oval shape. There are other dryglove systems on the market designed to integrate with the QCS oval system but with the exception of the Ellipse and Si-Tech’s Antares systems all the others render the wrist system round.
The Si-Tech QCS oval wrist system (the platform the Ellipse integrates with):
The Ellipse System was designed to integrate with the Si-Tech QCS oval wrist system. It is important to be familiar with the components of this system for the discussion of the Ellipse system. The QCS oval wrist system is comprised of the following elements:
1. PU ring - This is a flexible polyurethane ring that is glued into the end of the arm sleeve of the drysuit. This is the base of the wrist cuff system.
2. Rigid oval ring - This is a removable ring that retains the user’s choice of silicone or latex wrist seal. This rigid ring provides the oval shape of the wrist cuff system as it is pressed in into the PU ring to lock the wrist seal in place. The seal is effectively sandwiched between the PU ring and the rigid oval ring.
3. The wrist seal - The QCS oval system comes standard with a silicone wrist seal but the system will work just as well with a latex wrist seal.
The Ellipse System:
The Ellipse system replaces the rigid oval ring of the QCS oval system with its own rigid oval ring (I refer to this as the “suit side ring”). This ring is slightly longer than the one that comes from Si-Tech as it has an additional groove for the o-ring that forms the seal with the glove side ring:
The Ellipse System come in four flavors:
1. The complete kit - this version of the Ellipse system comes with a pair of suit side ring, a pair of glove side rings, glove retaining o-rings, sealing o-rings, protective/cosmetic silicone bands, a small container of silicone grease, an o-ring tool, an instruction and care card, and a case
2. Dry Glove attachment only - this version of the system comes with just the glove side rings, glove retaining o-rings, sealing o-rings, a small container of silicone grease, an o-ring tool, and a case.
3. Ellipse Suit Rings only - this verision of the system comes with only the suit side rings and the protective/cosmetic silicone bands and a case.
(note: the suit side only option does not come with the wrist seals as depicted, but does come with the black and orange case)
4. The 4th version of the system is unadvertised as it is primarily available to drysuit manufacturers and shops that do customization of drysuits. This version includes everything in the complete kit along with the addition of the PU rings and silicone wrist seals of the Si-tech QCS oval system.
Unboxing and setup:
Packaging
The packaging of the system is snazzy. It all comes neatly packed in a nice black and orange case. What one will do with the case after installing the system, who knows....but it is a nice case. I guess one can use it to store things like the instructions/care card, the o-ring tool, and small container of silicone grease. Or perhaps some small backup dive torches might fit in and could be protected by the case during transit to and from the dive site....the sky is the limit for this thing.
Suit side ring
The suit side ring of this system is nearly identical to the rigid oval ring of the Si-Tech QCS oval cuff system. The primary difference is that the Ellipse suit side ring has an extension that juts out beyond the PU ring when installed that serves as the home of the sealing o-ring and the connecting point of the glove side rings.
The wrist seal is mounted and sandwiched using the rigid oval wring the same way that it is with the rigid oval ring of the QCS oval system, the ring is pressed in the exact same way.
Some tips for getting this setup properly:
1. If you have the QCS oval system already installed in your suit AND you find the orientation of the oval comfortable for you, then take a sharpie and mark the edge of the PU ring or the edge of the cuff of your suit. You will use these marks to line up the suit side ring of the Ellipse system when you reinstall your wrist seal.
2. If you are not happy with the orientation of the oval or only have the PU ring installed, then don the suit without wrist seals and rigid oval ring installed and shake out your arms. With your arms hanging comfortably at your sides have someone mark the PU ring in-line with the pinky and thumb side of your hand...you will use these marks line up the oval suit side ring of the Ellipse system.
3. When you install the wrist seal on the rigid oval suit side ring, smear a light coat of silicone grease around the bottom portion of the wrist seal from the edge to about a half inch in-ward (13mm)...this will make installing the ring and seal a breeze. Don't use too much lube, just a very light coating. This helps things press together smoothly without damaging the silicone wrist seal.
Glove side ring
The glove side rings have very low height profile (measurements provided below) and are obviously designed to have the drygloves of choice mounted on them.
All the product demo videos show a latex glove being mounted and I was concerned before purchasing them if I would be able to mount SHOWA 720 gloves on them. Impressively, i was easily able to mount the SHOWA gloves on the oval glove rings.
When mounting the gloves one needs to be aware of the orientation of the glove on the oval rings. With SHOWA gloves this is easy as one just lines of the SHOWA trademark on the glove cuff with Fourth Element trademark molded into the glove ring.
The suit side ring and the glove side ring are incredibly light weight. My initial impression had me questioning the robustness of this product...but I reminded myself that I would not be hammering nails with it. I am not a materials expert but I imagine the rings are some sort of fiberglass reinforced plastic and in use did not have any concerns about their robustness.
O-rings, O-ring tool, Silicone bands
The kit comes with a pair of orange o-rings and a pair of black o-rings.
The orange o-rings are mounted in the groove in the edge that juts out from the suit side ring and serves to retain the glove side ring and seal the system water tight.
The slightly firmer black o-rings are used to retain the gloves on the glove side rings.
The silicone bands have an o-ring type lip molded into the inside circumference of one edge. They are stretch over the glove ring after the gloves are mounted to serve as a sort of backup reinforcement to keep the glove retaining o-ring in place, to protect the edge of the glove around the circumference of the glove ring, and as a cosmetic band adorned with the Fourth Element logo.
Fourth Element recommends removing the orange sealing o-ring from the suit ring when not diving with drygloves, and replace it with the silicone bands. They provide a nifty tool to pry the o-ring from the groove in the suit side ring. This tool is sharp and is not really necessary to remove the orange o-ring.
Silicone spaghetti equalization tubes
The Fourth Element Ellipse system does not come with any of those thin spaghetti like silicone tubes that are used to equalize between the glove and the suit. Lots of divers seem to not use them, but they do work and not only help the diver equalize the gloves but also get warm air from the suit into the glove to keep hands a little more comfortable during cold winter dives. Even though lots of folks don't use them, their addition would have been a nice detail along with a 2nd pair of those silicone bands...but don't fret 15 feet of 2mm OD x 1mm ID silicone tubing can be purchased from amazon.com for a nominal fee....so nominal that one questions why Fourth Element didn't include any in the kit.
