operation, carefully review and understand all aspects of this Owners Manualand
thoroughly practice operation using the simulator mode prior to actual use. When in
actual use, carefully compare indications from the GPSMAP 185 Sounder to all avail-
able navigation sources, including the information from other NAVAIDs, visual
sightings, charts, etc. For safety, always resolve any discrepancies before continuing
navigation.

ence, the user is encouraged to try to correct the interference by relocating the equip-
ment or connecting the equipment to a different circuit. Consult an authorized deal-
er or other qualified technician for additional help if these remedies do not correct
the problem.

Warning
The GPSMAP 185 Sounder should not be used as a
navigational aid or depth sounder to
prevent collision, grounding, boat damage, or personal
injury. The digital depth displayed is the depth under
the transducer and not necessarily the front of the
boat. By the time a depth is displayed most of your
boat may have already passed over that area. We rec-
ommend that you operate the boat at very slow speed
if you suspect shallow water or submerged objects.
