My all time favorite spear gun is a "Bottom Scratcher." It
was designed/developed in 1939 by Wally Potts and perfected
by the Bottom Scratcher spear fishing club of San Diego,
California. It is the original California long gun,
constructed of by the joining of a simple tube SS handle
containing a one piece trigger to a 1&1/4 inch dowel barrel,
and a long balance bar that was either made of wood or SS.
In the very early days if spear fishing around 1950 Wally
sold a Bottom Scratcher gun to Paul Hoss a member of the
Dolphins spear fishing club which had won the very first
spear fishing meet in Laguna Beach in the Summer of 1950.
When he sold it to Paul who lived in a suburb of LA, Jack
Prodanovich is reported to have said to Wally that "Selling
a gun up north was like selling guns to the Yankees." And he
was correct. Paul disassembled the gun did some
modifications that improved the trigger pull and began
producing a very close copy affectionately became known as
the "Hoss gun" by the "Yankees" of Los Angeles and Orange
County. The Hoss copy was cosmetically and functionally
identical in every respect except for the Sturgil muzzle
which was the muzzle of choice for all guns used by serious
Yankee spear fishermen. The guns which were made by Wally
and Paul were all custom made therefore no two were exactly
identical. It was reported substantially less than 100 were
made in a 30 plus year period by Wally and some where
between 20 and 30 by Paul in about a 10 year period.
Needless to say they were difficult to obtain and are now
scarce and highly prised by those who own them, or
collectors of diving memorabilia.
Known through out the spear fishing fraternity as the
"California long gun" and on occasion the "Long Tom," they
were made for long shots at big fish in then the clear
unpolluted waters of SoCal.
I was fortunate to have ended up with two. My own personal
custom gun and a friend's who after being chased out of the
water by a shark decided that spear fishing was not for him,
so he sold it to me a half what a bare unrigged new one
My guns measure 7 foot 9 inches plus the point which can
have many configurations and lengths adding as much as a
foot if the Prodanovich point impact aka power head was
used. It has a sling pull of 4 foot 8 inches and the 5/16
diameter SS arrow rides on the first rails to be installed
on a spear gun. It has a balance bar that extends
approximately 15 inches behind the trigger mechanism.
It was made during the era of the kettle cured rubber. I
can't recall when surgical rubber for spear gun slings
became popular but I think in the mid 1950s. I used 28 or
less inches of surgical tubing for power when it became
popular and readily available. I do vividly recall the first
time I test fired it at Ships Rock off Catalina using the
then new surgical slings...the Arbalete type slide ring
exploded totally disintegrated ! The arrow went flying in to
the blue water never to be seen again by man--or at least
me...so slide rings from aerospace material was custom made.
A number of years later I influenced Joe La Monica who
developed the Voit/ Mares/JBL gun to began producing a very
strong SS slide ring based on my design
My first and my favorite gun has a custom (aka home made)
"San Diego" style "dump pack" constructed from a piece of SS
sheet, a SS Piano hinge, several lengths of WW 11 webbing
and a SS rod as the release pin. The dump pack contained 200
feet of yellow 1/8 Polypropylene line fan folded into small
bunches secured by two pieces of a bicycle inner tube (they
won't rot) terminating with a small WW11 water purification
bag modified into an automatic Co2 inflation float. It has a
15 inch SS balance bar
Gun number two is equipped with a huge six inch "Riffes
Reel," produced and marketed about 30 years ago by a now
defunct San Diego company by the name of Aquacraft. The reel
holds about a jillione miles of hard lay tuna trolling nylon
line. I can not recall how much it holds and I have never
been reeled there fore cannot accurately state with any
reasonable amount of certainty the amount of line on the
Riffe's reel but it is a lot! It originally came equipped
with a 15 inch balance bar, which the former owner trimmed
to eight inches. I found this too short and extended it to
it's original length of 15 inches by the addition of a piece
of 1 &1/4 wood dowel.
Do I still use the guns" Heck no, especially when one Bottom
Scratcher/Hoss gun sold on E bay several years ago for
$2200.00 plus dollars.
I have several custom wood guns I made about 20 or more
years ago that I currently use, but another story for
But-- I still have wonderful memories of the Bottom
Scratcher and years gone by.
