Contoured Carbon Speargun Tube With Track
%100 carbon contoured (AKA cuttlefish) speargun barrel with built in track, gloss 2x2 carbon twill finish
Speardiver contoured (AKA cuttlefish) carbon speargun tube with built in track and gloss 2x2 carbon twill finish. If you need a rigid light carbon tube to bring up the bands inline with the shaft to reduce recoil and improve accuracy, with enough internal volume to float a large capacity stainless steel reel, this is the tube for you. If not using a reel, the contoured carbon tube combined with the Speardiver RTX speargun handle, Speardiver Shark open muzzle and 7mm shaft, requires 140 grams of lead in the front and 50 grams in the back to sink the speargun.
The contoured cuttlefish carbon speargun tube is open ended i.e. not sealed. It has an inner diameter of 26mm at both ends to fit most standard handles and muzzles, 2mm wall thickness, and an outer diameter of 30mm. The bottom of the track is 1mm higher than the rest of the round tube exterior, for a total of 3mm distance/thickness from the 26mm inner diameter. The tops of the track ridges are 10mm apart and accept up to an 8.5 mm shaft.
This tube inner diameter fits the insert peg, and tube track lines up perfectly with these components
- Speardiver Shark muzzle.
- Speardiver open muzzle.
- Speardiver roller muzzles, standard and inverted.
- Speardiver RTX handle.
- Ermes Avatar speargun handle, standard muzzles and roller muzzles.
- Many standard speargun handles and muzzles from other manufacturers with peg ID close to 26mm. Some adjustments to components may be necessary, such as reducing the peg diameter a little by sanding or using a shim to increase diameter. The peg will fit and the track will line up.
- Any custom wood hybrid build.
Options
- Add two plugs. Add two compression rubber plugs to your purchase to seal the tube yourself. We use these plugs to seal Speardiver carbon and aluminum spearguns. All that's needed to install the plugs in an aluminum tube is an approximately 5/8" diameter rod to collapse the plug pushing at its center, thereby reducing its diameter and making it possible to slide down the tube. With carbon tubes these plugs are used as a backing under an epoxy pour. If needed more rubber plugs are sold separately.
- Seal tube. We will plug the tube for you and guarantee no water intrusion. Specify the distance of the plugs from each tube end in the message field at checkout. If lengths are not specified tube will be plugged to accommodate Speardiver components which have standard length insert pegs.
Speardiver tip
Carbon barrels are very strong and can withstand high stress from most directions, but are susceptible to cracking when expansion force is applied to the tube walls from the inside. More so when the tube is manufactured using a two piece mold as is the case with this contoured tube. Round tubes are manufactured with a mandrel and are less susceptible. For successful assembly the insert peg diameter of speargun handles and muzzles must closely match the inner diameter of the carbon tube. There should be little resistance when inserting the peg in the tube, the fit should be snug not tight. Forcing a handle or muzzle into a tube opening that's too small may crack the carbon tube. When necessary, reduce the insert peg diameter by sanding incrementally, working carefully and testing fit at every stage.
