CST Competition – Blades for Demanding Spearfishermen
Are you in search of blades that will provide you with incredible thrust and withstand the most challenging conditions in spearfishing? Allow us to introduce you to CST Competition blades, the result of years of development and testing by the Croatian national spearfishing team (which has won top honors in international competitions over the past decade).
The Perfect Choice for Competitive Spearfishermen and Professionals
CST Competition blades are true competitive tools that will deliver top-notch performance in all conditions. These all-round blades provide outstanding thrust, especially when resurfacing at depths exceeding 30 meters, which is crucial for diver safety. Moreover, these fins are ideal for shallow water diving, where spearfishermen often spend up to 7 hours without excessive strain on leg muscles and joints.
Exceptional Durability and Reliability
CST Competition blades are designed with exceptional durability in mind. Extensive testing and use by experienced spearfishermen who dive more than 200 days a year, for several hours a day, have proven that these blades maintain their performance after more than 5 years of use. The thrust they provide even after this time is almost identical to the first day, which is an extremely rare quality among carbon blades.
An Investment for the Future
CST Competition blades are more than just blades – they are an investment. If you are a demanding spearfisherman who expects top performance (thrust and power), comfort, and durability, these blades are the ideal choice for you. You can use them for years without worrying about their reliability or comfort.
Let CST Competition blades become your secret weapons in spearfishing. Get them today and experience the difference in your diving experience.
GENERAL FEATURES
A revolutionary new design and structure of fin with variable blades, harder around the foot at the top and softer at the end towards the tip. Our ultimate carbon layer positioning inside each blade created using the latest LASER technology ensures that every blades is almost identical. The power and feedback from each kick allows for continuous fluid movement without any dead spots even during vertical assent; they offer the ultimate feedback of nerve and speed.
CONSTRUCTION
Fibres: 100% high-tensile carbon
Resin: specially formulated epoxy resin used in marine and general industrial composite areas. All systems are Germanischer Lloyd approved.
WATER RAILS
BLACKTECH water rails with variable height and high efficiency designed to decrease all the turbulence in bending phase made of special rubber highly resistant to abrasion and which allows blades’ high reactivity and efficiency. They allow higher stability and better handling underwater. These water rails come in a recognizable red colour.
BLADE TIPS
Blade tips are shaped to give the maximum amount of thrust with the smallest amount of energy consumption.
LOOK
Much attention has been paid even to the smallest details in the aesthetics of BLACKTECH fins and blades, including their high-end finish. The extraordinary mirror surfaces of our blades both front and back is BLACKTECH’s unique difference. Waterrails are red. Modern and attractive designs are used throughout. We offer everything you need to fall in love with your fins.
TECHNOLOGY
Advanced VRTM (Vacuum Resin Transfer Moulding) technology is used in the production of BLACKTECH carbon fibres blades, high temperature and high degree of applied vacuum, which lead to a component with 0% void level, without defects, with a uniform matrix/reinforcement ratio across the whole blade. Constant ambient temperature and humidity is used in compliance with the most demanding and modern standards. The blades are twice subjected under 14 hours post curing process in temperatures controlled through PLC (Programmable Logic Controller) with a deviation of less than ± 0,1°C in the chamber.
