Fish Finder GPS
When you are fishing with your boat in uncharted waters you definitely need a fish finder gps to keep track of where you are travelling.
While sailors have been using marine GPS for years now, anglers are starting to rely on marine GPS units that are specialized for finding fish and at the same time secure your positions.

Trolling have become one of the most popular fishing activities now and being equipped with quality boating electronics is very important. Common electronis are VHF radio, GPS and a fish finder or better; you can buy units that combine GPS and fish finders. Those have the great advantage of generally saving money over buying separate units, and they are typically console mounted equipment.
Here is some basic info about GPS Systems.
GPS satellites broadcast the time and data about their location constantly and a GPS receiver compares signals from at least three or four GPS satellites to determine it's own location.
A Global Positioning Satellite receiver calculates out how far away it is from each satellite based on how much time it takes a broadcast signal to travel from the satellite to the GPS receiver.Since the location of each GPS satellite is known, the receiver's location can be set by "triangulating" the distances from several satellites.The device will automatically determine its location, with accuracy of about three meters.
Most units come with maps covering major rivers and lakes in Canada and the US and of course their coastline. The majority of those automatically include recording of waypoints so you can find your way back very easily, and are compatible with computers, so you can include additional maps if necessary.

Here is some basic info about Fish Finders / Depth Sounders
Fish finders use sonar, a sound wave sent through the water. The diameter of the sound wave increases as it travels through water column, and when it meets a solid object within the cone formed by the sound wave, it bounces back to the transducer and records the shape of the object and the depth.If the signal doesn't bounce back immediately it will reach the bottom. Soft bottoms like mud and weeds will absorb the signal while harder bottoms will reflect a stronger signal back to the fish finder. These nuances will let you know whether there are any fish in the area you are in.
Fish finders GPS can be either mounted or handheld. The mounted ones are typically more costly and are available in dual frequency models, which enable to have more accurate fish to depth readings.
