Pop Ups &
Deep Water
Due to several
request from customers asking what effects depths of water
have on the pop ups, I have carried out some tests using a
Watch Makers Pressure Testing Vessel (this device is used by
watch makers to test if a wrist watch will remain waterproof
at a set depth).
Below is a set of images showing the pressure vessel, the
size of pop up being tested along with details of the rig
and split shot which has been added, the depth at which the
test was carried out and the time/duration of the test.
  |
Image 03 shows a detailed close up of the pressure tester’s
pressure gauge.
You will notice that the inner circle of figures relates to
feet (depth at which anything inside the vessel can be
pressurised to) and is probably the only thing most of us
will be interested in |

Let the Tests Begin
Testing a
“Tip” @ 20 feet
 |
 |
 |
 |
|
Image 04 shows
a single “Tip” pop up and a size 7 E.S.P. T6 Raptor hook
which has been balanced with a number 4 split shot and
placed in the pressure vessel in an Un-pressurised
state. |
Image 05 shows
the pressure vessel pressurised to a
depth/equivalent of 20 feet (as shown on the gauge) |
Image
06 shows the “Tip” pop up after 24 hours of
immersion at a depth/equivalent of 20 feet and I
think the effects on the “Tip” at this depth are
negligible.
|
Image
07 shows the “Tip” pop up after 48 hours of
immersion at a depth/equivalent of 20 feet and I
think the effects on the “Tip” at this depth are
still negligible, which leads me to the opinion that
one could confidently use this type of setup at
depths of up to 20 feet for at least 48 hours
knowing that your presentation will remain spot on. |
Testing a
11 miller @ 40 feet

Image 08
shows a single 11 miller pop up and a size 7 E.S.P. T6
Raptor hook which has been balanced with 3 x number 6 split
shot and placed in the pressure vessel in an
Un-pressurised state |
Image 09 shows
the pressure vessel pressurised to a depth/equivalent of 40
feet (as shown on the gauge)
|
Image
10 shows the 11 miller pop up after 48 hours of
immersion at a depth/equivalent of 40 feet and I
think the effects on the 11 miller at this depth are
negligible, which leads me to the opinion that one
could confidently use this type of setup at depths
of up to 40 feet for at least 48 hours knowing that
your presentation will remain spot on. |
Testing a 13 miller @ 40 feet
 |
 |
 |
 |
 |
|
Image 11 shows
a single 13 miller pop up, Korda size 6 L.S.X. hook complete
with micro swivel and line aligner. The rig was then
balanced with a small amount of putty and 3 x number 6 split
shot and placed in the pressure vessel in an
Un-pressurised state.
|
Image 12 shows
the pressure vessel pressurised to a depth/equivalent of 40
feet (as shown on the gauge)
|
Image
13 shows the immediate effect of the initial
pressurisation of the pop up to a depth/equivalent
of 40 feet, which shows the rig has dipped very
slightly under the pressure.
|
Image
14 shows the 13 miller pop up after 24 hours of
immersion at a depth/equivalent of 40 feet. I think
the image speaks for its self with the centrally
position number 6 shot now forming the point of
balance. |
Image
15 shows the 13 miller pop up after 48 hours of
immersion at a depth/equivalent of 40 feet. You can
now see for yourselves that the difference in
buoyancy between this image and the 24 hour image is
negligible |
Testing a 11 miller @ 60 feet
 |
 |
 |
 |
 |
|
Image 16 shows
a single 11 miller pop up and a size 7 E.S.P. T6 Raptor hook
which has been balanced with 3 x number 6 split shot and
placed in the pressure vessel in an Un-pressurised
state. If you look very carefully you can see that the lower
shot is just a hairs breath above the bottom of the vessel.
|
Image 17 shows
the pressure vessel pressurised to a depth/equivalent of 60
feet (as shown on the gauge).
|
Image
18 shows the immediate effect of the initial
pressurisation of the pop up to a depth/equivalent
of 60 feet, which shows the lower shot has dropped
very slightly under the pressure and it is now
resting on the bottom of the vessel.
|
Image
19 shows the 11 miller pop up after 24 hours of
immersion at a depth/equivalent of 60 feet. I think
the image speaks for its self with the centrally
position number 6 shot now forming the point of
balance.
|
Image 20 shows the 11 miller pop up after 48 hours
of immersion at a
depth/equivalent of 60 feet and I think the effects
on the 11 miller at this depth are not good in terms
of buoyancy, but having said that the hook is still
clear of the bottom of the vessel, which leads me to
form the opinion that one could confidently use this
type of setup at depths of up to 60 feet for at
least the first 24 hours knowing that your
presentation will remain spot on and if you wish to
leave this presentation any longer than this (48
hours), I will leave that one down to you.

Testing a 13 miller @ 60 feet
 |
 |
 |
 |
 |
|
Image 21 shows
a single 13 miller pop up, Korda size 6 L.S.X. hook complete
with micro swivel and line aligner. The rig was then
balanced with a small amount of putty and 3 x number 6 split
shot and placed in the pressure vessel in an
Un-pressurised state.
|
Image 22 shows
the pressure vessel pressurised to a depth/equivalent of 60
feet (as shown on the gauge)
|
Image
23 shows the immediate effect of the initial
pressurisation of the pop up to a depth/equivalent
of 60 feet, which shows the balancing putty at the
end of the rig has dropped a negligible amount under
the increased pressure.
|
Image
24 shows the 13 miller pop up after 24 hours of
immersion at a depth/equivalent of 60 feet. I think
the image speaks for its self with the number 6 shot
nearest the hook now showing just clear of the
bottom of the vessel with the hook still stood
upright and in a good position, ready for a take.
|
Image
25 shows the 13 miller pop up after 48 hours of
immersion at a depth/equivalent of 60 feet. I think
this image also speaks for its self as all the split
shot are now laying on the bottom of the vessel and
the hook is leaning over at an angle which is not
good for consistent hooking, which leads me to form
the opinion that one could confidently use this type
of setup at depths of up to 60 feet for the first 24
hours and after this time the pop up would need to
be change to maintain an efficient hooking set up.

Testing a
11 miller @ 100 feet (the kiss of death)

Image 26 shows
a single 11 miller pop up and a size 7 E.S.P. T6 Raptor hook
which has been balanced with 3 x number 6 split shot and
placed in the pressure vessel in an Un-pressurised
state
|
Image 27 shows
the pressure vessel pressurised to a depth/equivalent of 100
feet (as shown on the gauge).
|
Image
28 shows the immediate effect of the initial
pressurisation of the pop up to a depth/equivalent
of 100 feet, which shows the lower shot has dropped
under the pressure and it is now resting on the
bottom of the vessel.
|
Image
29 shows the effects of the pressure after just 5
minutes of immersion, with two of the three split
shot now lying on the bottom of the vessel.
|
Image
30 shows the effects of the pressure after just 1
hour of immersion, with all of the three split shot
now lying on the bottom of the vessel and the hook
barely clear of the bottom of the vessel. I think it
would be fair to say “depths of 100 feet wrecked the
pops in a matter of minutes”.
|
Notes:
1/ As a
general rule of thumb, all Proper Job Pops take on the
equivalent weight of water equal to that of a single number
6 split shot in the first 2-3 hours of immersion in the
water.
2/ You
may of noticed that the tests I have carried out only show a
48 hour period of time, and I claim that my pop ups will
remain buoyant for at least 7 days. Now with the exception
of the “Tips” and depths approaching 60 feet or greater than
60 feet, I still stand by this statement as it has been my
findings that once the pop ups have taken on their initial
dose of water, and stabilised in their environment, they
will remain buoyant for at least 7 days.
Summary
I guess
that most of what is explained above will be of no practical
use to anglers fishing in depths of less than 40 feet as the
Proper Jobs are fairly unaffected by depths up to 40 feet,
but it’s always good to know what’s happening down below
just for confidence sake as much as anything else, but for
all you folk fishing the likes of Bundy’s Pit where depths
approaching 60 feet can be on the menu, I think the above
will be very useful. |
