Here we have the new submarine with the highest quality in the market. Sub-77, alias: Xiphactinus, is a submarine with a minimalist and innovative design, with a look of aggressive nature in all its facets.
Submarine Construction The submarine, like any other , float and dives stably by an air injection system thanks to an air pump, through a system of tubes with closures. After placing its corresponding ballast iron, stability problems have been solved by injecting polyurethan in two-thirds of the internal part,located in fore and aft.
The main material used is PVC (camera and external tube) .Also iron has been used for ballast and polyurethane for the internal cave. You can see a photograph of the internal part without the poliurethan and a photo of our great product!
