SUUNTO Combo Consoles

Introduction

The Suunto combo consoles for recreational use, allow you to create a personal combo according to your own specific needs. Analog gauges, dive computers and compasses fit together like building blocks.

The combos consist of four main modules: the pressure gauge module, the instrument module and two different compass modules.

The pressure gauge module is designed for the Suunto pressure gauges and it can also be used with the new Suunto Quick Release (QR). The basic combinations are displayed below:

Assembling the Combo Modules

1. CB-ONE module front cover with SM-36 pressure gauge in place (see section CB-ONE Module assembly)
2. CB-IN-LINE module front cover
3. CB-end piece or CB-71/STD compass (optional)
4. CB-IN-LINE module back cover with instrument
5. CB-ONE module back cover or CB-71/DS compass (optional)

CB-ONE Module Assembly

The CB-ONE Module is designed to fit the Suunto SM-36 analog pressure gauges.

Before assembling the CB-ONE module the hose cover needs to be fitted on the pressure hose. The hose cover ensures that the SM-36 pressure gauge fits properly on the CB-ONE module.

The Suunto Vyper and Zoop are delivered with a display shield.

SUUNTO Console Compasses CB-71/SK-7/STD and CB-71/SK-7/DS

The CB-71/SK-7 is available in two versions: the CB-71/SK-7/STD for attachment on top of the combo modules or the Cobra dive computer, and the CB-71/SK-7/DS for attachment on the back side of the CB-ONE module.

Compass use for divers

General instructions

Usually a compass must be held precisely in a horizontal position, otherwise the needle will sting. The SK-7 compass may however be inclined about ±30 degrees.

Sighting a compass bearing

Hold the compass so that the compass is in a horizontal position and the direction line points away from you. Turn with the compass until the direction line points at your destination, then turn the direction ring until the magnetic North needle is aligned between the slit marks. The front end of the direction line on the SK-7 shows your compass bearing, and as long as the North needle is aligned between the slit marks, the direction points toward your destination. The SK-7 compasses also have a side reading window, which also enables you to take a bearing by directing the compass towards the destination and by reading the compass bearing from the side window. This bearing can be memorized by turning the direction ring to that bearing.

Setting a given bearing or direction

The scale division on the SK-7 is 360 degrees clockwise from 0 degrees at North. Turn the direction ring until the front end of the direction line is at the desired direction. Turn the compass until the needle falls between the slit marks. The direction line now points in the desired direction.

Magnetic declination

Maps and marine charts are drawn in correlation to the geographic poles, while the magnetic compass needle is subject to magnetic declination which varies according to the location.

General orientation on the diving site

Before diving, check the main compass bearings at the dive site, paying special attention to memorizing the direction of the shoreline and bearings of landmarks that may be of importance.

Natural aids to underwater navigation

• The underwater extension of the shore's inclination tells the diver if he is following the shoreline. Be careful however as underwater ridges may lead you astray. Surface occasionally to check your position.
  • The dip and stratification of rocks on the shore can often be followed over large areas under water.

• Sand ripples usually form long lines parallel to the shore.

• The direction of currents should be noted by their effect on algae or drifting particles. Use the compass to check the bearing of the current.
• In shallow water, the sun's direction can be seen from shadows on the bottom, or by looking towards the surface.
• Swimming in a straight line along the bottom is greatly facilitated if you can line up three distinctive objects in your line of vision. As you reach the first one, line up a new one farther away, so that you again have three points determining your course. This way you can counteract the effects of side current.

Compass Balancing

The horizontal and vertical components of earth's magnetic field vary in different locations. For this reason Suunto compasses are balanced for 2 different zones. If the compass is used in an adjacent balancing zone the compass needle will tilt only slightly. However, the farther the compass is used from it's intended zone, the more the needle will tilt. In extreme situations the needle might stick. For this reason it is very important to know in which country the compass will be used.

Before usage

Depth gauge:

Before diving, check the position of the depth indicating pointer. Atmospheric conditions (altitude, temperature) may cause the point to not indicate zero. If this is the case, turn the adjusting screw located at the right side of the gauge to align the pointer to zero. The adjustment is to be made at the temperature of usage. Repeated unnecessary adjustments may cause excessive wear to the seals and eventual leakage.

CAUTION!

Do not attempt to adjust the water entry port located at the left side of gauge. Tampering with the port can cause damage to internal components. Do not pressure test gauge in air. Always immerse the gauge in water while pressure testing it.

Pressure gauge:

The hose has an end fitting with 7/16" 20 UNF-thread. If your regulator has a different thread size in the high pressure (HP-output) port, ask your dealer for the correct adapter. Always inspect the o-ring at the male thread to be sure it is clean and undamaged before connecting it to the regulator.

Always turn your air supply on slowly. Always turn the pressure gauge dial face away from your face when turning on the air supply.

Do not overtighten the hose at the gauge, the fitting is pressure proof even when tightened with fingers.

Service

Avoid subjecting the gauges to excessive shock loads such as those that might occur from being dropped or hit against an

immovable object. Do not subject the gauges to pressures beyond their maximum range. Temperature extremes can be damaging. In general, the gauges should not be exposed to temperatures to which you would not expose yourself.

CAUTION!

After use, rinse the gauges or the console with fresh water and store them out of direct sunlight, in a dry place at room temperature.

CAUTION!

Do not attempt to clean the gauges with anything other than water. Use of cleaning agents or compressed air can cause permanent damage. The introduction of any probe into the water entry port of the depth gauge or the pressure relief valve opening of the pressure gauge can also damage internal components.

Before prolonged storage the instruments should be removed from the console, rinsed with fresh water and stored separately.

CAUTION!

Do not attempt to disassemble the gauges. Special tools and training are required to perform the adequate service.

The instruments must be serviced by an authorized dealer every second year or after 200 dives (whichever comes first).
