Hollow Butt Pad

Hollow Bottom Plate for Freediving and Spearfishing by Mares in Collaboration with Apneautic

The hollow bottom plate is an essential technical accessory for open-water training, designed to be secured approximately 1 meter above the ballast weight located at the lower end of the guide line. This position clearly marks when the target depth has been reached, significantly reducing the risk of hitting the ballast weight during the descent.

Technical and Functional Features

• The fastening system is designed to allow installation without tying knots in the guide line, eliminating the risk of the lanyard carabiner connected to the freediver getting snagged.
• The shape is parabolic upward, optimized to allow a smooth, unobstructed descent.
• Structure with 32 holes around the perimeter for easy and secure attachment of tags, useful for marking depth or other relevant information during underwater activity.
• Compatible with ropes from 10 to 12 mm in diameter.

Materials and Dimensions

The plate is made from high-quality materials that ensure an ideal balance between mechanical strength and flexibility, essential for durability and performance in the water. Its low weight of 230 grams makes it easy to transport, even for freedivers and instructors who travel frequently, including by air.

• Outer diameter: 28 cm
• Weight: 230 g

Installation Instructions

1. Pass the guide line through the plate.
2. Tighten the fastening die at the desired distance from the ballast weight, recommended at around 1 meter.
3. Check the stability of the fastening, making sure there are no knots that could interfere with lanyard passage.

This design allows quick and safe installation, improving ease of use and minimizing potential issues related to the carabiner getting snagged during freediving and spearfishing sessions.
