One Shot Greece continues to develop highly specialized spearfishing accessories with the new Belt Floating Marker, a compact and intelligent solution designed to precisely mark productive spots on the seabed during spearfishing sessions.
One Shot is a respected Greek artisanal company focused on technical underwater hunting accessories and high-quality weight systems. The brand is particularly appreciated for its innovative approach to quick-release weights, variable weight systems and floating markers, all entirely designed and manufactures by One Shot with functionality and reliability as priorities.
Precise Marking of Fish Spots and Caves
The One Shot Belt Floating Marker is an extremely useful accessory for marking precise points on the seabed where fish, caves or interesting terrain have been identified during previous dives.
During spearfishing sessions this allows spearos to relocate productive areas very quickly and efficiently, especially in zones with rocks, holes or irregular bottom structures.
The floating section is produced using a long lasting very soft and lightweight material that guarantees fast ascent to the surface once released from the base. The buoy is offered in highly visible fluorescent yellow and white colors, ensuring excellent visibility even in difficult sea conditions.
Stainless Steel Base for Maximum Precision

One of the most interesting technical aspects of the One Shot Belt Floating Marker is the stainless steel base.
The carefully calculated weight and design allows the marker to descend rapidly and vertically toward the seabed with minimal lateral movement caused by current or water resistance. This means the marker can hit the exact point the diver wants to signal.
The stainless steel base weighs 125 grams, while the complete system reaches a total weight of 200 grams, creating an excellent balance between deployment precision and practical use.

Intelligent Belt Attachment System
The One Shot Belt Floating Marker is designed for quick and practical installation directly onto the weight belt.
The stainless steel base integrates a spring system that allows immediate attachment onto rubber belts while keeping the marker stable during movement. Release is equally fast and intuitive simply by pulling the marker away from the belt.
An important detail is the insertion space inside the base, which reaches 9 mm thickness. This allows compatibility with virtually all weight belts on the market, including thick rubber belts frequently used in spearfishing.

O-Ring Locking System and High-Quality Line

The connection system between the float and the base is particularly intelligent. Through a pressure-fit O-ring mechanism, the buoy can be inserted quickly and securely into the base and released immediately through traction.
The float also integrates an additional O-ring locking system designed to prevent the line from completely unwinding, while also helping the marker maintain a vertical position on the belt.
The Belt Floating Marker is supplied with:
- 30 meters of 0.5 mm polyester line
- final 1 meter section with larger diameter line
This configuration guarantees excellent visibility and practical management during use.
Compact Dimensions and Technical Characteristics
The dimensions of the One Shot Belt Floating Marker have been carefully optimized for practical underwater use.


The float external diameter is 6.6 cm with a thickness of 4 cm. Despite its compact size, the buoy maintains excellent visibility at the surface and minimal drag underwater.
Combined with the heavy stainless steel base and the intelligent release system, the result is a highly effective accessory for technical spearfishing.
One Shot Confirms Its Technical Philosophy
With the Belt Floating Marker, One Shot confirms once again its strong focus on technical functionality, intelligent engineering and artisanal construction quality.
For demanding spearfishermen looking for a precise, compact and reliable solution to mark productive spots on the seabed, the One Shot Belt Floating Marker represents an extremely practical and effective accessory.
