THE BASICS

When choosing a radar ski, there are so many factors to consider. Where should you start?

  • EXPERIENCE LEVEL
    Whether you're beginner, intermediate, or advanced, there is a ski for you.
  • SKI PROFILE
    The height and width of the ski all change how it will ride on the water.
  • CONSTRUCTION
    Radar uses nothing but the best materials for each and every ski.
  • WATER TYPE
    Skis for ripping it up on the course, and skis for carving out in open water.

CONSTRUCTION MATERIALS

  • PMI

    PMI Foam is leading the industry as a core with its lightweight, reactive qualities. More speed and instant connection is how that translates on the water.

  • PVC

    PVC has been an industry staple for well over a decade. It is trusted and proven as a core because of its long-lasting strength and quick response.

  • AERO CORE

    AeroCore is our exclusive formulation of polyurethane foam. With an amazingly high strength-to-weight ratio these skis sit deeper in the water for a forgiving, consistent ride.

  • ALL-TERRAIN CORE

    Our All-Terrain Core is the most forgiving construction we offer. A polyurethane core with paulownia wood stringers allows the ski to cross the wakes with ease.

  • TEXTREME

    Textreme is a manufacturer of spread tow carbon which allows us to reduce weight and increase strength. It most importantly provides us a more consistent flexing and durable ski.

  • INNEGRA

    Innegra is a dampening fiber that reduces vibration and increases strength. Innegra is woven into the Textreme to improve the performance and durability of the ski.

  • SIGMATEX

    Sigmatex is an industry leader in the carbon fiber world. Their looming process is computer controlled giving them the ability to use ultra-high modulus carbons with complete precision.

  • NFC ENABLED

    Putting Technology in the ski. An NFC Chip allows the consumer to get more information about the ski with just a touch of their phone.
