WARNING: This device should not be used as a navigation aid to prevent collision, grounding,
boat damage or personal injury. When the boat is moving, submerged objects will not be seen
until they are already under the boat or bottom depths may change too quickly to allow time for
the boat operator to react. Always operate the boat at very slow speeds if you suspect shallow
water or submerged objects.

HUMMINBIRD FEATURES
("Or why your 'Bird outperforms all other brands.')
Gold Plated Contacts - Gold is one of the best conductors of electricity known, and unlike other
metals, it will not corrode. This is why our waterproof flasher units are equipped with gold plated
contact points on both the transducer and power cable connectors.
Completely Waterproof-Tough inner and outer ABS material cases house all flasher units. Sealed
with watertight "0" rings so that rain, humidity, spray (including salt water) or condensation will not
affect your Humminbird.
Epoxy Based Printed Circuit Boards - We use a tough epoxy filled fiberglass printed circuit board,
built to military specifications. Unlike paper based boards, the epoxy based board will not crack or
break, and will stand up to long term use in rough water.
