Assessment Questions and Correct
Answers
How do you set a dive float? ✅You and the instructor will time setting the float so that
when you surface from setting it, the class is in the water with the instructor and on the
way to you. Set them up, inflate before you get in the water (more effective). Have a
good idea where you will set it, considering where divers will "land" and ANCHOR,
AUGER, or CLIP the float, but be cautious not to damage or disturb aquatic life and pay
attention to the anchor and line. Leave enough scope or reel to account for currents,
waves, tides, swells and rising tide.
What is the purpose of surface marker buoys and how do you properly use the various
types? ✅Purpose:
*Marking boundaries for mapping
*Search and recovery
*Alerting boat traffic to the presence of divers
*So surface support or an instructor can track buddy teams or groups (common in
specialty courses)
*Provide a line as a visual reference for ascending divers
Types and How:
* Surface Marker Buoy - inflate and set before you start the dive, be cautious when
securing to avoid harming aquatic life, when towing hold reel so you can release
immediately if necessary, don't attach it to your gear, keep tension on the line and
avoiding slack - pay attention to the line to avoid entanglement of yourself or others
* Delayed Surface Marker Buoy (DSMBs) -
have buoy and reel well stowed but accessible and ready for deployment with minimal
delay, hold buoy away from you and others, keep line on the reel taut to avoid
entanglement, inflate orally or using a second stage or accessory inflator and maintain
tension on the line as it rises, deployed just before ascent underwater, once it reaches
the surface keep line taut so it stands upright for max visibility
As a divemaster, what signaling and safety devices should you carry and know how to
use? ✅Dive community recommends that ALL divers carry at least two surface
signaling devices, not just certified assistants.
One audible: out of the way yet readily accessible in emergency, most commonly
located on BCD hose
*Whistles
*Air horns
, One visual: divers usually carry more than one, keep where you can get to them readily
*Signal tubes
*Surface marker buoys
*Inflatable signal tubes (many surface marker buoys double as signal tubes)
*Strobes
Considerations when setting a dive float include: ✅Finding insensitive bottom for
anchoring, accounting for current/waves/tide, considering where divers descending the
line will "land", retrieving the float at the end of the dive or end of the day.
A surface marker buoy may be used to mark the location of a buddy team or group.
✅True.
PADI Standards require certified assistants to carry: ✅Both an audible and a visual
signaling device.
What are the general steps for mapping a dive site, and what elements do you include
in a dive site map? ✅1. Identify central point or place buoy from which to gather data
and determine map boundaries. Use point as a fixed reference around which you will
draw the map
2. Swim a large search pattern or series of patterns that cover the area you're mapping
away from the point (U-pattern and straight-sided patterns that follow compass
bearings)
3. Record survey data on slate, note compass heading of each leg and measure
distance as you travel (count kick cycles or use a tape measure), record the depth of
each feature you find and it's distance on the pattern leg, determine the direct heading
and distance between key features
4. On each pattern leg, record distance where you hit specified depth increments (3
meter/10 foot increments e.g.) use interval depths for laying contour lines on finished
map
5. Draw out pattern you followed on graph paper in pencil, use protractor to keep
heading angles accurate and a ruler and graph lines to maintain scale. Assign each
block a distance (based on converting kick cycles to meters/feet) to trace pattern legs
and the distances between pattern legs. Mark on the pattern line each place where you
reached interval depth and features you want on the map
6. Connect the contour interval depths with lines to show contour. You can use shape of
the shore line to help extrapolate contour. Keep everything to scale (protractor and
ruler), fill in direct headings and distances between features
