Rob's Custom Riffe
One of the most common questions among divers is "what speargun
do you use?" My answer to that question varies from, "what
works for me might not necessarily work for you..." and continue
on to dodge the question, to telling specifically which gun I use
and even how it's rigged. But like most spearfisherman I have more
than one gun so I have to be specific when I refer to which gun.
My "Theory of Choice..." First of all, the conditions
you dive in narrow down the gear choices you need. However, there
is much room for personalizing and / or customizing, which is why
there are so many choices in the relatively small market of Spearfishing.
Have you ever noticed throughout the world there are about 10-15
different camo.
wet suits to choose from, about 10-15 long
blade fins available etc. etc. but there are about
300-400 different spearguns worldwide!!! Maybe more if you count
the garage guys that "design" their
own guns.
My point is, out of all these choices I have found ONE (1) gun
that can do everything for me and I call it my all-around
gun, the Riffe
Competitor 4X speargun. I emphasize me because,
as stated earlier, what works for me might not necessarily work
for you. I have found by sticking to one gun that has:
- Enough maneuverability -
"Enough" maneuverability refers to "not too much
and not too little." What I'm trying to say is obviously a
short gun is going to have great maneuverability BUT it's not going
to have much range. A long gun is going to have great range BUT
not much maneuverability. A maneuverable speargun is nice but how
fast do you really need to turn it... because if you need to turn
it super fast you probably shouldn't take the shot. On the other
hand, if an Uku comes up behind you point blank but your gun is
facing forward and if it takes too much effort and time to turn
a big gun 180 degrees, the fish will sense this and dig out.
- Appropriate Maximum Range for available fish and conditions
-
"Max Range" refers to the maximum possible range
that any modification or enhancement can give to a speargun. Naturally,
it's much easier to make a big gun shoot less distance than a small
gun to shoot a greater distance. "Appropriate" refers
to the fish and conditions you will be diving. You wouldn't need
a gun that shoots thirty feet if your visibility is ten foot and
the fish are ten pounds.
On my Riffe Comp. 4X I am able to tailor:
-
The amount of power -
I can load three (3) 5/8" dia. bands or less (and anywhere
in between) on the Riffe Comp. 4X. What this means is I can
shoot a small fish at close range with one (1) 5/8" dia
band, medium sized fish with two (2) bands and big fish with
all three (3) bands. Logically I load two bands for most
reef situations so I can either unload one band very quickly
if a nice "small species" of fish comes around,
or load the third band very quickly if something big comes
around. Due to the visibility in Hawaii I usually have the
time to do this on the surface because I can see the intended
target before I make my dive. However, many times I have
loaded or unloaded a band while sitting/laying on the bottom
or even mid-water.
-
Shaft length, diameter and style -
The Riffe mechanism can handle an amazing amount of strength
and shaft diameters. I can use a thin 1/4" dia. shaft
all the way up to 3/8" dia. shaft if I wanted to. However,
the barrel on the Comp. 4X is best weighted for a 9/32" or
5/16" dia. shafts. I can also use Hawaiian style, threaded "fixed
tip" style or "slip tip" style set-ups without
changing a thing on the gun and...
-
All the accessories that goes along with each particular set-up, limiting the "relearning" period
that is necessary when
you change your equipment or use a different gun completely.
The only slight exception is when doing what I call "Extreme
Blue Water Diving" where my 68" Mid-Handle Riffe Blue Water
Gun with Full Wing Kit, 3/8" dia. Shaft, slip
tip, four (4)
5/8" x 28.5" bands and release assembly is brought
out of the gun case during Ahi season. I can, and often times do,
use my 4X in the Blue for Ono's, Mahi etc. but there is no comparison
to the Blue Water Gun for its range and accuracy.
It would take me volumes to explain my reasoning that I decided on
a Riffe Comp. 4X as my gun of choice over all the many other choices
in the world so I will limit this article to the modifying / personalizing
of the gun to my requirements.

The Riffe Competitor #4X
The Comp.
4X is more or less balanced for a 9/32" dia.
Riffe spear shaft. With the shaft in the gun and the two (2) stock 9/16" x
26" bands the gun sits neutrally buoyant. The first personalization
I did was to experiment with the best ratio of power (overall band
strength) for the shaft and set-up. I found that two (2) 5/8" x
26" bands would fire very nicely and accurately without an
excess of recoil. This set-up worked quite well until the first "reasonable
sized" fish I speared easily bent or even broke the 9/32" dia.
shaft. I also noticed the weight of the shaft didn't have quite enough
impact on some species of fish over fifty (50) pounds. I tried simply
using a third (3) 5/8" x 26" band for the larger fish
but in many situations it still wasn't quite enough or the shaft simply
broke in half when a "large" fish scraped against the reef.
Next I tried a 5/16" dia.
shaft and found that the gun
became a bit negatively buoyant. I actually liked the fact that the
gun became slightly negative because it seem to help me on the descent
plus it seem to sit better in "moving" water, like near the
shore line. Of course the gun would float upward once it was fired.
Spearing the reef occasionally did nothing to the 5/16" shaft
where I'm SURE it would have bent the 9/32". Also, spearing
a "larger" fish that, again, I'm sure would have bent the 9/32" shaft,
did nothing to the 5/16 dia. shaft.
On the slightly negative side of things, I noticed the increased weight
of the 5/16" dia. shaft was affected by any decrease in
power, as the rubber bands age, greater than the 9/32" dia.
shaft. This meant I had to keep my rubber bands fresh and crisp. But
I love to make a cannon out of every gun I use so three (3) 5/8" x
26" bands just wasn't enough for me. I cut the bands to 24 inches,
simultaneously increasing my "band stretch" by two inches.
Remember, rubber has its "maximum stretch point (MSP)" which,
beyond the MSP you will simply be tearing the material and significantly
decreasing the life of the rubber band(s) so don't shorten them too
much.
I want to make it clear that the band power described above is what
I have found to be appropriate for me. I have shared my set-up
with others and some have come back with sprained wrists, chipped teeth
or bloody noses so BE READY!!! I have shot this set-up for so long
I don't even think about it so you will get use to it as well if you
decide to try the same or similar.
Now onto the shaft situation... I mentioned I changed from the stock 9/32" dia
shaft to a 5/16" dia but that's not all... Riffe's 5/16" dia.
Hawaiian style shafts are "milled" for the flopper. There
is good and bad about the milling... The good part is the flopper tucks
nicely behind the milling therefore creating a more hydrodynamic flopper
style shaft, however the milling also weakens the shaft. Now the 5/16" dia.
shaft has similar strength of a 9/32". So, what I did is
to take a threaded 5/16" dia. Riffe shaft and ground down
the thread to a nice, slow tapering, "sticky sharp" point
creating a much more penetrating point for those big fish situations.
It's so nice the tip has a tendency to keep me from taking those wild,
reef smacking shots that merely wound the fish and bend my tip...
I drilled my first hole at three inches below the point, which is
the standard distance for most Hawaiian
style shaft manufacturers.
Next, I drilled a second hole approx. three inches below the first
one for a second Hawaiian
flopper. The first flopper is fitted onto
the bottom side of the shaft, for best holding ability, and the second
flopper is fitted onto the topside of the shaft as a "back up." Having
two floppers on opposite sides serves several purposes...
-
Many times as a fish struggles the shaft can turn upside down.
If there is only one flopper on the bottom side of the shaft
there is a high likelihood that it may close and the struggling
fish may fight free. By adding a flopper it doesn't matter which
way the shaft turns because at least one flopper will always
be open.
-
On larger fish that is capable of breaking barbs, the second
barb gives a "second chance" if the first one should
break.
The gain in strength by using a non-milled shaft I feel far outweighs
the small gain in hydrodynamics of the milled shaft. Lastly for
the spear shaft, I like to polish the shaft to reduce the resistance
against the barrel when fired. When I remember to apply some silicone
spray to the track of the gun before a dive I notice an even smoother
release and even an increase in range. Keep in mind that only one
small improvement like polishing the spear shaft is NOT going to
make all the difference in the world... No, your gun will not double
its range or do the dishes and your laundry, but if you add up
all the many little modifications you do THAN you are making a
difference. Where's the limit???
I have tried many different shooting lines and they all have their
ups and downs. I have come back to monofilament
line due to its
speed, strength, cost and availability for the majority of applications.
The largest exception to this rule is when spearing large fish
in a cave or on the reef, like the Ulua (Giant Travally). I like
to change my line almost every time I go diving so I keep a spool
of it along with the proper crimps
and crimpers to do the job on
the spot rather than have to take it back to the shop. Keep in
mind that mono stretches so if you spear a big fish it may not
wrap on your gun properly anymore. Also, as a big fish stretches
the mono the mono becomes thinner and can pull through a crimp.
For this reason I burn the end of the mono at the shaft end and
double crimp it.
I believe in being ready at all times because you never can predict
what you will see. For this reason I always rig my gun with a breakaway
system attached to my float. For my application, I don't believe
in a reel because we have huge Ulua and pelagic fish close to shore
and both would spool a reel in a matter of seconds... and than
what? Many times I have been lining up on a two or three pound
fish and a fifty to one hundred pounder swims by... I never want
to blame my equipment for being inadequate or rigged improperly.
We, as freedivers and spearfisherman have plenty to think about
already so we don't want to compound this fact by using cheep or
poorly rigged gear.
Upgrades, modifications and personalizations... in general some
are factual some are theoretical but weather they actually help
your gun shoot faster and farther or if they just makes you feel
better and more confident in your equipment than I think it's at
least worth trying. Lastly, a word on technique for shooting your
new cannon... BRACE PROPERLY!!! Bracing properly will protect
your teeth but it will also increase range by allowing all the
momentum to push forward rather than backward and accuracy by holding
the gun still while the relatively slow spear shaft exits the barrel.
