Today, car gps navigation systems utilize some of the same technologies used to help boat operators reach their destinations.  If you own a boat, or are interested in boating, you may want to study car GPS navigation systems that are suitable for both environments.  In particular, you may want to look at the units manufactured by Lowrance.  Among other things, even if you do not purchase a unit for your car, you may be interested in a wide range of sonar devices.  This includes units that will help you locate schools of fish, as well as ones that will help ensure that you always know the depth of the water near the shore line.
