1. Which of the following is the primary purpose of an Evidence Recovery
Diver Certification program?
A. To train recreational divers to explore deeper underwater environments
B. To prepare divers to locate, document, recover, and preserve underwater
evidence using forensic procedures
C. To teach commercial divers how to perform underwater construction
operations
D. To train military divers for underwater combat missions
Answer: B
Evidence Recovery Diver Certification programs focus on forensic
underwater operations, including locating, documenting, recovering, and
preserving evidence while maintaining legal integrity and chain of custody.
, 2. During an underwater evidence recovery operation, what is the most
important principle governing the handling of recovered evidence?
A. Recovering evidence as quickly as possible regardless of documentation
B. Allowing multiple divers to handle evidence for verification
C. Maintaining a continuous chain of custody from recovery through final
disposition
D. Cleaning evidence immediately before transport
Answer: C
The chain of custody ensures that evidence can be legally authenticated by
documenting every person who handled it, every transfer, and every
procedure performed.
3. Before beginning an evidence recovery dive, the dive team should
primarily conduct which activity?
A. Equipment inspection and operational briefing
B. Removal of all underwater markers
C. Unrestricted searching without a plan
D. Immediate evidence collection
Answer: A
Pre-dive planning, equipment checks, and team briefings reduce risks and
ensure that recovery operations follow established forensic and safety
procedures.
4. Which underwater condition most significantly affects visibility during
evidence recovery operations?
A. Water temperature only
B. Salinity only
C. Turbidity and suspended particles
D. Diver experience level
,Answer: C
Turbidity caused by suspended sediments, algae, or disturbed materials
can severely reduce visibility and complicate underwater searches and
documentation.
5. What is the main purpose of establishing a search pattern during an
underwater evidence recovery mission?
A. To increase swimming speed
B. To ensure systematic coverage of the search area
C. To reduce the amount of documentation required
D. To allow divers to avoid using navigation equipment
Answer: B
Systematic search patterns help divers cover the entire area methodically
and reduce the likelihood of missing important evidence.
6. Which search method involves divers moving outward in expanding
circles from a fixed reference point?
A. Grid search
B. Circular search
C. Sweep search
D. Random search
Answer: B
A circular search pattern begins at a central point and expands outward,
making it useful for locating objects near a known underwater reference
location.
7. What is the purpose of underwater evidence markers?
A. To decorate the recovery site
B. To indicate diver positions only
, C. To identify and document evidence locations before recovery
D. To replace photographic documentation
Answer: C
Evidence markers provide reference points that allow investigators to
record the exact position and relationship of recovered items within the
scene.
8. Which factor is essential when photographing underwater evidence?
A. Moving the evidence into better lighting before taking pictures
B. Including scale references and scene context
C. Removing surrounding materials first
D. Photographing only recovered objects after cleaning
Answer: B
Proper underwater photography requires documenting evidence in context
and including measurement references to support later analysis and
courtroom presentation.
9. Why should evidence divers avoid disturbing the underwater scene
before documentation?
A. Disturbance improves visibility
B. Disturbance can alter evidence relationships and destroy important
information
C. Disturbance reduces dive time
D. Disturbance makes recovery easier
Answer: B
Maintaining scene integrity is critical because the original position and
condition of evidence may provide valuable investigative information.
