Back pack with 2” webbing harness and stainless buckles.

The strong delrin cam buckle is lightweight and capable of withstanding rigorous use. The 2” wide webbing is supple, which can be threaded through the buckle easily, but its distinct weave creates ample strength required to perform heavy duty tasks.

Being the heart of a technical buoyancy system, all IST back plates are press formed individually and all edges on both sides are deburred and rounded to avoid cutting the harness.
Apart from the 5cm (2”) slots for the harness and crotch strap, there are 10 additional perimeter holes for mounting equipment such as stage bottle, torches etc. There are also 3 sets of holes, each 11 inches apart, along the centre of the plates for attaching the single tank adaptor or twin tank bands. These attachment holes give the diver the option to fine tune the location of tank(s) according to their particular torso length..
The aluminium back plate BP-4 is made from type 6061aluminium for its strength to weight ratio. At 700g (1.54lb), this plate is ideal for warm water diving or travelling, when the lesser weight the better.

HB-1 basic harness. Set includes: 3.2m long 2" wide nylon webbing with centering grommet, 6 * WK-4 strap keepers, 2 * DR-1 bent D-rings, 2 * DR-2 flat D-rings (stainless belt buckle is available separately)

Comfort orientated, this harness has a set of heavy duty, anatomical shoulder pads and adjustable chest strap. Together with conveniently located chest D-rings and quick release buckles, all are carefully sewn together with the same durable webbing used in the basic harness to ensure no structural integrity and strength is sacrificed in the process. 2” (5cm) CROTCH STRAP, both harnesses come complete with high tensile strength crotch strap. It helps to hold the BCD and all equipment attached safe and secure around the torso.

BP-4 Aluminium back plate not included, BB-3 stainless buckle sold separately and HB-3 crotch strap sold separately.

HB-3 crotch strap: Include - soft 2" Webbing w/belt loop,  2 * WK-4 strap keepers, 2 * DR-2 flat D-rings

HB-4 back plate pad and surface marker pouch.

Handle for Back Plate

This fully-featured back inflation BCD with its technical style inner air-cell and protective, three-dimensional spandex gusseted outer shell, offers unrestricted body movement in a way that a traditional BCD can not. The horseshoe shaped wing allows the tank to be positioned closer to the body and removable bungee cords can wrap around it to stop unwanted drag when partially inflated underwater. These streamlined designs are very hydrodynamic and translates into less energy expansion while swimming. The padded harness provides ample adjustments for that personal fitting.

Sojourn is a significantly lighter and compact BCD which divers will appreciate. It will not take up bulk of the precious baggage space and the weight reduction meant more personal items can be brought on a dive trip. Despite this special feature, Sojourn is durably constructed with the same care and attention like other BCD in the IST range. It can be used just like any heavier example on many weekend underwater excursions.The Personal Harness System (PHS) can be easily adjusted to suit so a secure and personal fitting can be attained. The simple but effective integrated Ballast Removal System (BRS) removes the need of a weight belt in most conditions.

This is a traditional jacket style BCD which provides all the basic requirements a diver needs at a much affordable cost. It is comfortable, easy to use while durability and reliability is not sacrificed in the process. The tough 1000 codura shell can withstand rigorous usage and the power inflator and pull dump assembly is tried and tested.

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
