DMS Travel Hybrid Roller speargun

DMS Travel Hybrid Roller speargun

The twin barrel "Dead Man's Switch" speargun moves & tracks effortlessly through the water. The speargun shaft has such minimal contact with the track such that friction is almost nonexistent. The design allows the shaft to "freefloat" with 3 support points. The engineering behind this concept is inspired by the free floating barrel designs seen in the most accurate rifles in the world in the firearms industry. It's the shaft that truly matters for precision and accuracy. Horizontal alignment of the roller wheels in tandem with an optimized shaft design has proven to be the perfect concoction for an effective roller speargun.  The power is delivered via a two stage loading hybrid band layup. Made in the USA.
