4COURIER OWNER’S MANUAL

1.0 Introduction

This information has been developed for your safety.

Please read and understand this manual completely

before using your new Sherwood dive computer.

1.1 Simply Reliable

Congratulations! You are now the owner of a new

Sherwood Scuba dive computer. You’re about to experi-

ence the Sherwood difference in diving equipment—

products that are simply reliable. At Sherwood, we

focus on the type of diving you do, then design products

that address your specific needs. The simple, purposeful

designs of all Sherwood equipment provide you with reli-

able, trouble-free performance, dive after dive.

1.2 Key Features

Among the Courier’s key features:

■■The Courier fits Sherwood’s CNC-3™ Compact

Navigational Console. This console combines the

Courier with an analog submersible pressure gauge

(SPG) and easy-to-use top- and side-reading compass.

The console also features clip anchors on either side, to

help attach it to your BC. The Courier computer mod-

ule will also fit in most other standard instrument con-

soles and circular wrist mounts.

■■The Courier activates automatically upon descent. It

need not be manually activated prior to entering the

water (although we recommend doing so).

■■It automatically adjusts for altitudes up to 7,882

ft/2,400 m, and is capable of functioning at depths up

to 328 ft/100 m.

COURIER OWNER’S MANUAL 5

■■The Courier displays a variety of data, including date,

time of day, current, max and average depths, no-

decompression dive time elapsed and remaining, and

water temperature.

■■The Courier provides visible alarms for violation of

ascent rate, no-decompression status and mandatory

decompression stops.

■■If needed, the Courier can calculate deco requirements

for stops as deep as 39 ft/12 m.

■■The Courier’s Random Access Memory (RAM) enables it

to hold and display log data on ten dives.

■■Depending on use, the Courier’s battery can last up to

several years before needing replacement. Battery

replacement may be done by an authorized Sherwood

dealer, or by the consumer, following the instructions

appearing in this manual.

1.3 Common Sense Warnings

As is true of every piece of diving equipment—including

all dive computers—the Courier’s abilities are not limitless.

Thus, there are certain limitations and restrictions of

which you must be aware, and certain precautions you

must take, when using the Courier.

Before using your Courier, it is extremely

important you read the following points—as

well as similar warning and caution notices

that appear throughout this manual—and fol-

low the recommendations they provide.

Failure to do so could result in damage to or

loss of equipment, serious personal injury

or death.

6COURIER OWNER’S MANUAL

■■The Courier is designed for use by certified, recreational

divers who have maintained a sufficient level of knowl-

edge and skill proficiency through a combination of for-

mal training, ongoing study and experience. It is not

intended for use by persons who lack these qualifica-

tions and, thus, may not be able to identify, assess and

manage the risks scuba diving entails.

■■The Courier is not intended for use by commercial, mili-

tary or technical divers, whose activities may take them

beyond the commonly accepted depth limits for recre-

ational diving.

■■The Courier is designed for use by divers breathing nor-

mal compressed air. It does not provide a means of

tracking exposure to the elevated partial pressures

divers may encounter when breathing Enriched Air

Nitrox (EANx).

■■Although the Courier is capable of calculating decom-

pression stop requirements, this ability is provided as a

safety feature only, should recreational divers accidental-

ly exceed the No-Decompression Limits (NDLs). Dives

requiring mandatory stage decompression carry sub-

stantially greater risk than dives made well within no-

decompression limits. Divers should not use the Courier

to plan or execute dives that will intentionally exceed

no-decompression limits.

■■The Courier is designed to be used by only one diver at

a time. Divers should not share a single Courier—or

any other dive computer—on the same dive.

Additionally, no diver should lend his or her Courier to

anyone else until it calculates that no measurable resid-

ual nitrogen remains after previous dives, and is able to

enter its Sleep Mode. Further, no diver should use his or

her Courier for repetitive dives—unless that same

Courier has accompanied him or her on all previous

dives in the same repetitive dive series.

COURIER OWNER’S MANUAL 7

■■Neither the Courier—nor any other dive computer

presently available—physically measures the amount of

nitrogen present in body tissues, or the rate at which

this nitrogen is being absorbed or released. Instead, the

Courier monitors depth and time, and uses this data to

work a mathematical formula designed to emulate how

individuals in good general health and whose physical

characteristics do not place them among those at high-

er risk of decompression illness are assumed to absorb

and release nitrogen from body tissues. Thus, the

Courier cannot compensate for factors such as age,

obesity, dehydration, cold or exertion, which experts

believe place divers at greater risk of DCI. If these, or

similar factors apply to you, use the Courier—and any

other dive computer or dive table—with even greater

caution.

■■Experts still know surprisingly little regarding the exact

nature and causes of decompression illness (also known

as decompression sickness, DCI or DCS). Susceptibility to

DCI may vary substantially from person to person and

from day to day. Neither the Courier—nor any other

dive table or dive computers—can guarantee that you

will not suffer decompression illness. Even though you

use these items correctly, you may still suffer DCI. Use

your Courier conservatively, and in conjunction with

other dive planning devices, such as dive tables. Do not

rely on the Courier, or any similar device, as your sole

means of avoiding decompression illness.
