Product Information

The Mares Shaft SLGun 17-4PH D6.5 Tah1Barb is a Tahitian-style spearfishing shaft built from 17-4PH stainless steel, designed as a replacement or spare shaft for a single-fin pneumatic speargun. It is offered in five lengths, from 115 cm to 160 cm, so you can match the shaft to your gun's barrel length.

Who it is for

This shaft suits spearfishers who need a spare or replacement shaft for a single-fin pneumatic speargun in the 7 mm class. Because it ships in five lengths, it suits divers running different barrel sizes across their pneumatic gun lineup.

Key details

Material: 17-4PH stainless steel (Tahitian-type shaft)
Shaft diameter: 6.5 mm per the manufacturer's product code (Mares' own description text refers to it as a 7 mm class shaft, a naming note from the manufacturer's page itself)
Shaft designation: Tah1Barb, Tahitian-type, per the manufacturer's product code
Compatible use: single-fin pneumatic spearguns in the 7 mm shaft diameter class
Length options: 115 cm, 130 cm, 140 cm, 150 cm, 160 cm

Compatibility and sizing

Choose the length that matches your pneumatic speargun's barrel to maintain correct shaft travel and power. This shaft is built for single-fin pneumatic spearguns using the 7 mm shaft diameter class; confirm your gun's specified shaft diameter and length before ordering, since pneumatic guns are sensitive to shaft fit.

Frequently Asked Questions

What lengths does the Mares SLGun 17-4PH D6.5 Tah1Barb shaft come in?

This shaft is available in five lengths: 115 cm, 130 cm, 140 cm, 150 cm, and 160 cm. Choose the length that matches the barrel length of your Mares single-fin pneumatic speargun so shaft travel and loading are correct.

Is this shaft 6.5 mm or 7 mm in diameter?

Mares' own product listing shows a naming inconsistency: the product code designates it as a D6.5 (6.5 mm) shaft, while the description text refers to a 7 mm class. Both figures come from the manufacturer's page, so confirm fit against your speargun's specified shaft diameter before ordering.

What type of speargun does this shaft fit?

It is built for single-fin pneumatic spearguns in the 7 mm shaft diameter class and carries the Mares Tah1Barb Tahitian-type designation.

What tip style does the Tah1Barb shaft use?

Mares designates this shaft Tah1Barb, a Tahitian-type shaft in 17-4PH steel. Confirm tip configuration against your speargun's requirements before ordering.

Great purchase and "Like New" as advertized.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.
