A ‘Woomera’ is a wooden Australian Aboriginal spear-throwing device. Similar to an atlatl, it serves as an extension of the human arm, enabling a spear to travel at a greater speed and force than possible with only the arm...
Hunt Master's Compound Inverted Roller Head Speargun Conversion Kit is the modern-day ‘Woomera’, enabling a spear shaft to travel at a much greater speed and force than possible with only the traditional open-head muzzle speargun.
Why choose the ‘WOOMERA’ compound invert roller head?
Compound (Invert) roller guns - This is the equivalent of a compound archery bow, in comparison to a normal bow. The compound roller gun produces more power, efficiency, accuracy and virtually zero recoil on the handle. These guns have shot many world-record-sized fish and give a massive advantage over other conventional guns when targeting larger fish. When loading a large number of rubbers, it doesn’t place strain on the handle and your hand when firing.
Our Dilemma solved!
The WOOMERA Compound Speargun Inverted Roller head has finally addressed all the issues of previous invert rollers in one new and unique design. When designing this head, our team of advanced divers and spearos sat with our engineers and manufacturers for weeks on end to fine-tune what is needed for the ultimate roller head.
We wanted a head that can be an ‘All-Rounder’ invert roller head. A head that can hold hundreds of kilos of pressure; be used for single flopper shafts, double flopper shafts and alternate setups according to what species we are targeting.

Construction
-
Made using start-of-the-art CNC/CAD design with special injection molding. This makes each stage of the production process precise and consistent.
-
The plastic is mixed with over 32% carbon, making it both stronger and lighter in weight
-
The design ensures there is a protective “arch.” The purpose of the arch is to ensure the line on the shaft doesn’t tangle up or get in contact with the rollers whilst firing the speargun, meaning increased safety and effectiveness.
-
Sleek and compact design with an internal hole to allow for extra rubber kickers when setting up rig ups for very large fish
-
Rollers make it easier to load and can also be used to fit many different guns on the market.
-
Embedded anchor point to tie off your speargun muzzle bungee or feed through your reel line
-
Marine-grade stainless steel for all metal parts used
-
The design is unique by using ‘self-lubricating Teflon washers’ embedded behind the roller wheels that reduce friction whilst firing your speargun for both versions (standard/ball bearings).
-
Tested by our team and sponsored divers whilst targeting large game fish like Marlin and Tuna - and proven to hold over 9-10 16mm rubbers, showing amazing durability and strength and no failing or weak points during tests.
