Lead Weight for Freediving and Spearfishing Belt - 1 kg

Essential belt Lead Weight for buoyancy compensation in freediving and spearfishing. The 1 kg weight ensures precise, adjustable balance during descents and dives, improving depth control and trim management in the water.

The shape and material are optimized for maximum mechanical strength, ensuring durability and safety when used in the underwater environment. Ideal for anyone who needs stable weight distribution without compromising freedom of movement.

BreakAway Plug: release system for spearguns

The BreakAway Plug is a 14 mm diameter rubber device designed to ensure controlled release of the shaft from the speargun after the shot. It works together with a 12 mm BreakAway Ring, mounted on the speargun, creating a safe and reliable system for managing the shaft during spearfishing.

This system is particularly suitable for bluewater hunting and targeting large fish, especially when using floatline, bungee, and buoys instead of a reel to manage the retrieval line.

Technical features and benefits

• Partial adjustment: allows accurate tuning to suit different hunting conditions and target species.
• Selective release: unlike traditional systems that release the shaft on every shot, the BreakAway Plug releases the shaft only if it is pulled free from the ring when the fish runs, preventing accidental releases during normal use.
• Rubber material: provides elasticity and mechanical strength, ensuring durability and safety while freediving.
• Compatibility: designed for use with 12 mm rings, making it easy to integrate into your existing spearfishing setup.

Recommended use

1. Insert the BreakAway Plug onto the speargun shaft, connecting it to the 12 mm BreakAway Ring mounted on the speargun body.
2. Adjust the tension to achieve a balance between security and easy release if the fish runs.
3. Use together with floatline, bungee, and buoys to make handling easier during spearfishing, especially in deep water or with large fish.

The BreakAway Plug is an essential accessory for spearfishers using spearguns equipped with retrieval systems other than a reel, ensuring greater efficiency and safety when using the shaft during the shot and retrieval phases.
