Learning Goals （學習目標）• Learn about the steps to long range and short

range planning （長程與短程潛水計畫）• Be introduced to the steps to follow to safely

conduct your dive• Learn why it is important to plan your dive

and dive your plan （潛水計畫的重要性）• Be introduced to the importance of recording

each dive you do （潛水紀錄的重要性）

To further reduce the risks in diving, it is essential that you plan and prepare your dives in advance.

Planning is divided into sections:1. Long range planning 長程計畫2. Short range planning 短程計畫3. Preparing to dive 潛水準備4. Conducting your dive 進行潛水5. Post-dive review 潛水後的復習Planning ensures that: 1. Well functional equipments 裝備正常運作 2. What to expect at the dive site 值得期待的潛點3. Avoid any last minute rush 避免倉促4. Make reservations if needed 預約的必要性

Long-range Planning

• A long-range planning begins many months ahead of a major dive trip

Step 1. The objective of your dive? 潛水的目的Step 2. select your location 地點- primary and alternate 主要潛點與替代潛點- background information about the location; from books, dive

resorts, stores, clubs, instructors, and divemasters.- Visit the dive site in advance 行前造訪潛點- Emergency services in the area 緊急救難服務- Transportation 交通

Step 3. to determine the date and time of your dive or dive trip - Avoid schedule conflicts 行程衝突- No alcohol within 12 -24 hrs. of a planned dive 勿飲酒- Consider about the tide, wind, and local weather conditionStep 4. Make travel arrangements- Make airline, hotel, and boat reservationsStep 5. to determine your equipment needs.- Water temp. influences dive suits you need- Weight and buoyancy- Conditions of your BC and regulatorsStep 6. Refresh your dive skills if necessary

*** Establish a “to-do” list is helpful!!!

Short-range Planning

• Short-range planning starts about a week before your dive- Check all of your dive gears- Buy things you need in advance (sunscreen, seasickness

medication, sea drops, spare parts for dive gears etc…)• 1 or 2 days before, check the weather trends, water

conditions, tides, and the long-range weather forecast.• ALWAYS be sure to leave a copy of your plans with someone.- Destination and dive sites- Contact telephone number- The date and time you expect to arrive back home.

Preparing To Dive

• The day or evening before your scheduled dive- Pack your gear in two bags: dive gear and personal items1. Pack your dive gear in reverse order of its use2. Don’t pack weight belt with your dive gear- Personal items: towel, extra dry clothing,….

• Get a good night’s rest and no alcohol at least 12 hrs. before diving!!!

Conducting Your Dive

• When you and your buddy arrive at your selected site, you must agree on how you will conduct your dive before you enter the water.

- Site survey- Emergency plan and information- Activity- Buoyancy- Air- Gear and go

• Site SurveyBefore you even suit up, evaluate the conditions at the site to

determine if they are acceptable for your planned activity.

Once you decide you can dive, you must determine which buddy will be the leader of the team.

• Emergency PlantYou must discuss contingency plans, emergency procedures, and

accident management.- Agree on what to do if you runs out of air under water- What to do if you get separated under water- How to call for help if needed

• Activity- Selecting only one activity as the purpose of any one planned

dive- Communication under water- To decide entry and exit points and dive pattern- Setting limits for depth, time, and air supply based on your

dive table and computer• Buoyancy- Check your buoyancy• Gear and go- Check your gears

Diving Your Plan

• You must carry out the plan you have made for your dive. You must not abandon the dive plan midway through the dive.

• Plan ahead when you dive. Remind one another of your depth and time limits, and follow your plan throughout the dive.

• When you are prepared for a dive, many benefits result and these benefits are worth the time you take to properly plan and prepare.

Contingency Planning

• Contingency planning is an important part of dive planning. For each step of your plan, you need to have a contingency plan.

• When you are planning the direction of your dive, be sure to consider an alternate route or alternate exit point to be used if conditions change while you are on your dive.

Recording Your Dive• After each dive, you should record information from your dive

in your logbook.• What information should be included?- The number of your dive- The date- The water visibility- Your starting air pressure- Your ending air pressure- Your maximum depth- Location of your dive- The name(s) of your buddy- Remarks about the dive
