2. Installation
2.1 Hardware Installation
The sonar is typically mounted with the receiver element on the top. The transmit and receive elements are
arranged such that they are angled at ± 10° about the horizontal axis which should be taken into account when
mounting the Sonar.
Any metallic clamps should be electrically insulated from the sonar body by either rubber or plastic strips or
mounting brackets of at least 3 mm thickness and extending at least 3mm beyond the clamp boundary to
reduce any galvanic corrosion effect. Non-metallic clamps are preferable; if metallic clamps are used (especially if
they are different in composition to the material used by the sonar) they should be painted or lacquered with at
least three coatings. The body of the Gemini 1200ik is made from aluminium, alloys containing copper such as
brasses or bronze should be avoided.
CAUTION
Although the sonar head is rugged, it should be handled with care. This is
particularly important in the area of the transmitter and receiver elements on
the front face, and the electrical connectors on the back face. The plastic guard
fitted to the front face of the unit will not protect the sonar against significant
impacts or erosion damage.
2.2 Mounting Options
The sonar must be held in place securely when fitted on a vehicle. Standard
orientation is top & bottom however the sonar image can be flipped within
software should the sonar be mounted inverted.
The Gemini 720/1200ik Sonar Mount Assembly shown here can be
purchased as a mounting accessory kit from Tritech.
