From now on, let's talk about our swivel and tachometer
First of all, by using a swivel, we receive two
major advantages never before.
Very quiet observation becomes possible.
Next, a stable flight plan can be set up.
Let me explain these two points.
I will explain from now on, the swivel is a rotary
joint with built-in slip ring system. The inside
of the swivel is filled with pressure equalizing oil and has
high withstand pressure.
The graph below shows casting up to 6000 m, with each swivel
when swivel is installed between the armored cable and the water
"Tachometer" (to be described later) was attached
to the pulling of the armored cable (Evergrip) and "Orientation
meter" was attached to the water sampler.
is about 190 revolutions with Armored Cable, green is 5
samplings with water sampler.
The direction of rotation of the armored cable
changed from the vicinity of the bottle, but the rotation
number and direction of rotation will change for each cast.
The cause has not been elucidated.
From the results of this
test, by attaching a swivel, you can see the following
· Armored cable
· The water sampler does not turn
· Since the water sampler does not receive the
rotational force of the cable, it does not turn
around and it is not swayed. will
· Therefore, the water sampler can descend and
rise quietly, can be measured
Let's see it, let's see it
cable can turn freely
· Since twisting (twisting) does
not occur, there is no turbulent winding of the
there is no turbulent winding, the winding speed
of the cable becomes constant
Winding time never gets longer
· Since there is no twist, a Free
Since twist does not occur, it
does not kink
· Because it does not kink, cable repair
and its time disappear.
· Cable repair parts become unnecessary
· Because it does not kink, it
does not drop the water sampler
· Since it does not kink, you
can use without cutting the cable, so do not
casting can be done for a long time.
This will allow for planned casting
The water sampler is
not affected by the rotational force
of the armored cable
· It does not rotate.
· It is not swayed greatly.
· As a result, the water sampler
can be controlled while maintaining
By using the swivel, it is
possible to easily and unequivocally stable
operation and very precise observation.
Do not rotate the water sampler, you can
measure without swinging.
It is a feature of the swivel.

· Stable performance can be maintained by periodic
inspection every year.
· It is cheap

Tachometer / compass
It is a compass of memory type using geomagnetism.
Designed for measuring
and recording the rotation of the armored cable. It is made very small, lightweight and can be
attached to Evergrip.
It is possible to measure and record for a long
time so that it will not interfere with water sampling and
Fastest sampling period: 0.5 seconds
Memory amount: Continuous 6 days (at 0.5 second
interval) Since it is a nonvolatile memory, it does not
disappear even if the battery runs out
Continuous observation for about 6
months using lithium battery is possible.
Please replace the batteries because they use
commercially available CR2 batteries.
