The Giga Jul is our favorite device for multi-pitching because it has three different modes cleverly built into one small, affordable, and simple device. A belay set containing the Giga Jul belay device and HMS Strike Screw carabiner. Because of the way the carabiner sits in a small cut-out of the side, the extra carabiner actually pulls the rope out further and reduces friction while defeating the assisted brake. Not an issue with thinner half and twin ropes though. All of the testers who used this device said that they agreed it was less jerky and "grabby" than the similar Mega Jul, which is a good thing. Quantity : Reference Unit : is equal to : Conversion Factor : Unit : 1: gigajoule = 1 : gigajoule: 1 = 1000 : megajoule: 1 = 1000000 : kilojoule: 1 = 1000000000 For situation-dependent belaying and abseiling, especially in alpine terrain. This includes when it’s used for belaying normally from the bottom of a pitch, when used in guide-mode / top-down belay and even when rappelling. Our sample’s verified weight is 4.4 ounces and it is roughly twice as big as a Mega Jul. Lead or top-rope belaying with the Giga Jul can be done in either assisted braking or manual mode. It’s not without a few drawbacks though. Lowering a climber in assist mode requires keeping upward pressure on the thumb loop, or using a separate carabiner threaded through the release hole on the back for leverage, and takes a bit of effort and is also fairly jerky. With the Giga Jul, this need disappears, and this level of versatility is what makes it an easy choice for our Top Pick award for Multi-Pitching. The range is now exclusively assisted-braking only, hence the original Jul is no longer available. We only recommend using a round stock carabiner with this device. TR and Lead Belay in Manual Mode: When using the Giga Jul in the manual brake position to belay a lead climber it works much the same as any regular tube-style device. The assisted braking function which supports the braking force can be activated or disabled by an intelligent mechanism. After six months of use we give the verdict here, especially with a view to how it suits UK trad climbing. The rappel is quite smooth, not at all jumpy like some assisted brake units can be and definitely smoother than the Mega Jul. The assisted braking function which supports the braking force can be activated or disabled by an intelligent mechanism. The Giga Jul can replace both your guide ATC and auto-locking device (like your grigri) all while still being able to do every action you need while climbing. The Giga Jul weighs 4.3 ounces, which isn't too heavy but is almost double the weight of some other auto-block belay devices designed for multi-pitching. Billed as the most versatile belay device ever, the Giga Jul is the latest in a long line of belay devices under the Jul label. M (manual) at the top, A (assist) at the bottom, as indicated by the arrows. While the Mega Jul introduced several cool and unique features, the fact is that most people don't enjoy using it because it is too small and therefore has way too much friction from the rope unavoidably built into its use, making it effortful and annoying compared to the competition. If you're roping up, you're going to need a belay device... How to Choose a Belay Device for Rock Climbing. A gigajoule is a unit of energy in the International System of Units.

Shown here is the slider bar, in yellow, that you move from one side of the device to the other in order to change modes. If compared directly to an ATC-Guide or a GriGri, the Giga Jul falls a little short in both departments.It doesn’t give slack quite as easily as both devices, and it is fairly heavy, weighing 100 grams (roughly 70 grams little less than a GriGri). Although you must still hold onto the brake strand, the braking assist does most of the work, effectively locking the device when the climber falls, and easily holding their weight as they rest, requiring minimal sustained gripping or effort on the belayer's part. On our independent scale the Giga Jul weighted 4.3 ounces, which is pretty light, but a fair bit heavier than comparable devices we compared it against. You can also use a carabiner as a lever arm clipped into the small eye hole on the back to aid with this process, not shown in this photo. Certification: EN 15151-2. The Rex roared at me and so I ran. PRODUCT INFORMATION. Everyone we know belays the second on multi-pitches using auto-block, so we can't imagine a functional multi-pitch device that doesn't allow this usage. Order-No. The assisted braking function which supports the braking force can be activated or disabled by an intelligent mechanism. The performance of a belay device is heavily influenced by the diameter and condition of the climbing rope used. GiGa ne connaît pas votre mot de passe et ne peut pas ouvrir vos fichiers. We know many people who commonly carry a tube and a GriGri up multi-pitch climbs, just for this same versatility. The symbol for gigajoule is GJ. The Jul … A definite lose-lose! Of course this means that the friction will slowly improve over time as these edges get worn through use. Of course this isn’t the only factor that determines the amount of friction developed by a given rope diameter but does provide some insight into which devices work better for thicker ropes and which for thinner ropes. The … * measured midway along slot as shown in photo. I think this is due to the sharp, non-beveled edges along the top of the side plates. The answer is 1.0E-6. One demerit to Edelrid for nearly doubling the weight from the Mega Jul (120g vs 65g, respectively). So I figured it was going to die but it had killed a carno. Using a, I-beam carabiner like the one shown here added significant friction to the system, making it much harder to pull out the needed slack quickly. Top-Down, Direct Anchor Belay: When belaying a second up directly off an anchor with the Giga Jul, the rope seems to rub on the edges of the device even more than when belaying from below—even with skinny, sub-9mm single ropes. In manual mode, the device functions just like a standard tube and has some added friction grooves that help you catch and hold a falling climber. The device will likely outlast any traditional all-aluminum belay device but won’t last as long as an all-steel unit like the Mega Jul. Edelrid Giga Jul . The Half and Twin ropes that I tested with the Giga Jul worked quite well though. Of note is that the slider bar must be slid into manual mode for this usage, and the thumb loop points toward the wall, which is the opposite of the orientation used by the Mega Jul, but is ultimately more intuitive. With a single rope the device feeds out rope fairly well but taking in slack is less smooth as the rope rubs on the bottom edge of the side plates increasing friction. We most often lowered climbers in assist mode, because that is how we usually belayed them. The Giga Jul is the latest in Edelrid’s assisted braking device range. Also worth noting, will steel construction where the rope wears this device will last you far longer than aluminum counterparts (especially if you are in sandy climbing … 22% of the market.
