Sailing Vessels
Additional considerations apply when installing the Radar scanner on a sailing vessel. A separate purchase
mast mounting bracket is highly recommended.
Review the following important mounting requirements:
• When mounting the Radar scanner onto the mast, check that the unit is not fouled by the sails,
especially when tacking.
• Depending on the type of sailing vessel and the design of the sailplan, a Radar scanner guard
(separate purchase required) should be attached to the mast if the sails or rigging contact either the
Radar scanner unit or the mounting bracket (separate purchase required). See the illustration
Example of a Radar Guard Installation.
WARNING! Without a proper Radar guard, serious damage can result to the Radar mounting
bracket and the Radar scanner itself. In extreme cases, such damage could result in the Radar scanner
unit being pulled off the mast. Therefore, it is recommended that a Radar scanner guard should be
mounted additionally and separately to the Radar scanner mounting bracket.
• To prevent the risk of the Radar scanner falling after it has been damaged, the security lanyard
supplied with the mast bracket (separate purchase required) must be secured properly to the mast
and to the Radar scanner, according to the instructions provided with the bracket.
If a safety lanyard is not supplied with the mounting bracket, contact your local dealer for appropriate
parts. Do NOT attach other equipment to either the Radar scanner or the bracket.
• Maintenance: Humminbird strongly recommends that you check the condition and security of the
bracket mounting feet, the security lanyard(s), the Radar scanner guard, and the Radar scanner
itself, on a yearly basis (or more frequently depending on environmental applications). Any fittings
should be replaced as appropriate.
