Polyethylene spar buoys have unique technical features that provide significant advantages over conventional steel buoys. Over the years they simply come cheaper since, because:

• Light weight and anchoring
• Lighter deployment equipment
• Less maintenance and costs
• Guaranteed lifetime 20+ years
