on Line helps the diver remain at a certain depth when performing decompression stops or when waiting becomes necessary at the down line. The strong 2.5cm (1”) wide nylon webbing is 2.1m (7ft) long and is attached to a storage pouch, which has a loop to fit any 5cm (2”) webbing for carrying purpose. The 4mm thick, high tensile 304 stainless steel hook is sewn on the other end and is easy to use.

The attempt to remain at a location while drift diving just has become easier with IST’s drift hook. It is made from high tensile 304 stainless steel, which can withstand the curent and plenty of abuse. The 5mm thick hook is sewn to strong nylon webbing measures 2.5cm (1”) wide, 2.1m (7ft) long and a storage pouch that can be carried on any 5cm (2”) webbing.

These double-layer buoyancy air cells are made with special 3 dimensional panel construction, which are streamlined and can achieve the lift capacity without increasing much resistance. The outer shell is constructed from tear resistant, 1680 denier ballistic nylon and its durable anti-corrosion zip encloses the replaceable inner air cell inside, which is made from 420 denier TPU material. The inflator hose and dump valve’s cut outs in the outer shell are urethane protected from fraying. The circular air cell design eliminates the chance of gas being trapped thus providing technical divers with precise buoyancy control any time during a dive mission. The JT-30 is designed for single tank use

By adding weight poucches (sold separately), tank adapting accessories, back plate padding to JT31-D series back pack, a complete BCD emerges. They all have hydro-dynamic air cells, which allow for excellent streamlining. By minimising drag, swimming effort is reduced and buoyancy control becomes much easier than with a conventional jacket style BCD. The minimalistic harness also give more chest room for easier access to attachments and better maneuverability underwater.

The JT31-D- These are complete BCD's with 30Ibf (14kgf) lift double-layered air cell for single-tank use with harness and back pack plate being the difference between the two. Comes complete with the single tank adaptor and its twin tank straps the maximum size of scuba cylinder can be used is 15L (95cft) in capacity.

The IST technical diving weight pockets are made from durable 1680 denier ballistic nylon and only the highest grade of Velcro and corrosion resistant zips are used as the pocket closure. They can be attached to the harnes through their 5cm (2”) webbing loops.Weight release can be simply done by unclip the quick-release buckle and pull down then the cartrige containing all the weight will fall out. JT-WP-4 is designed to hold up to 4kg (8.8lb) of weight in each pocket. It also leaves ample space on the waist part of the harness for attaching other underwater equipment.
