MAQ SONAR 22KHz, Technical And Installation Manual

Page: 14 / 107

Before proceeding with the installation, please reference the attached Installation drawings and
diagrams. These drawing show typical lengths and dimensions for short stroke and standard stroke hoist
installations of the 90KHz, 60KHz and 22KHz Sonar.
Before installing the Sea-Chest or Sonar it is IMPORTANT to measure the angle of a vessel during
typical search and catch situations as well as pitch and Roll measurements. Sea-Chests, that were
angled as much as 10° off the typical vessel angles during standard Sonar operation have been
observed in the past. This will make operation of OMNI Sonar very difficult and also reduces
performance greatly.
These issues should all be considered on installations in new or existing Sea-Chests.
