Dynamic Surface Marker Buoy Line Retractor
The SLR25 is a dynamic surface marker buoy line retractor designed to keep the buoy positioned above the diver while reducing drifting, tangled lines, and unnecessary drag in the water. It improves surface visibility, enhances maneuverability, and helps create a safer and more controlled diving experience in busy waters and boat traffic areas.
Comparison: Connecting to the buoy while diving
BEFORE: Traditional methods
- Fixed-length lines and floating buoys can drift unpredictably, creating excess slack, tangled lines, and reduced control in the water
- Surface marker buoy positions may move away from the diver, reducing visibility accuracy and increasing collision risks in boat traffic areas
AFTER: SLR25 solution
- Dynamic line retraction and extension keeps the surface marker buoy aligned directly above the diver in real time
- Reduces drifting, improves maneuverability, and provides more accurate surface visibility for safer diving conditions
Consistent Connection
The SLR25 dynamic diving line retractor features an auto-retracting 25 m line that helps keep the surface marker buoy positioned directly above the diver for improved visibility, reduced drift, and safer diving in boat traffic areas.
