Hello, my name is Moritz. Today we're going to take a closer look at the Jewel 2. The
Jewel 2 is a auto-tuber made out of stainless steel that is perfectly suitable for sport
climbing, top roping, single pitch climbing in general and also gym use. It can work with
ropes from 8, 9 up to 11 millimeters. Therefore, if you're having a fuzzy 10mm rope, it will
still work smoothly and will be an enjoyable experience to climb with. It works in similar
ways as the Mega Jewel, meaning that there are no movable parts and it's purely based
on its geometry. What's happening here is that the dangling rope tilts the device and
the carabiner locks into this groove, therefore creating a passage that is too narrow for
the rope to pass through and locking it off. To get lowered, I just put my thumb in here
and can lower him really smoothly due to the increased sweet spot that I have because of
the bigger lever and the good leverage. Definitely adds an extra level of safety to the whole
belay system. For demonstration purposes, I took my hands off the brake line, never
do that in real life. You should always have a head on the brake rope. If you're trying
to lower someone with a lever and things are not as smooth as you expect them to be, there's
one trick I'd like to show you, which also works for the Mega Jewel, by the way. When
you put your thumb on the back, point the finger through here and you just gradually
tilt the device and then you can lower really smoothly and easily. This might be especially
interesting if there's a big weight difference between climber and belayer. The device is
made out of stainless steel, therefore it won't wear out. You'll only have to buy it
once. You'll never have to replace it because of wear. Yet, the carabiner will wear out
since it's aluminum and the rope runs over it and after excessive lowering, what not,
you get this big groove there and every half year you have to replace your carabiner, which
is why I'm actually using a steel carabiner here. You might think, hey, I'm not going
to use a steel carabiner. It's super heavy. In my world, I think it doesn't make a big
difference if I carry an ounce more or less to the gym. The strike screw weighs in at
around 70 grams. The steel carabiner weighs in at around 110 grams, 120 grams, so it's
not that much of a difference and this carabiner won't wear out, so I can highly recommend
to belay off a steel carabiner, even if it's something you haven't thought about yet.
We already showed the Jewel 2 at the last show, if you remember. It had a plastic coating
all around and the functionality was a little bit different. The version we showed last
year, which never made it into production, did not lock off the rope completely. The
idea was that there's still some slippage involved. Our philosophy now is and will be
for the future to only have fully locking tubers, only auto tubers. No more kilo-jewel, no more
jewel, only Jewel 2 and mega-jewel and both of those lock off completely.
All known fact, in Germany this device is called Jewel Quadrat.
