garmin striker 4 portable fishfinder combo
Most combo sounders can detect water temperatures. This information is very useful when trying to find out if you're riding on a current channel in open waters. Fisherman use slight temperature variations to find areas of water that could hold large pelagic animals like marlin.
The solar functions at 83/200kHz frequencies. However, the optional XNT9 DB 74T transmitter uses 50/83/200 kHz frequency and can increase the depth capability by up to 3,000 ft. DualBeamPlus sonar can simultaneously use both frequencies to create images for split-screen or blended displays. The sonar is able to cover a 60° cone at 83kHz. The 200-kHz frequency covers a narrow cone measuring 20 degrees.
In terms of value, the Lowrance HDS 9 Live Fish Finder is one of the best GPS fish finders on the market. A large LCD display, GPS and mapping capabilities make this a top choice for fishers. The large LCD display makes it easy to use the GPS combo fishfinder combination on the water. Lowrance is the best choice for anyone who wants to fish or enjoy the boat.
Many of the newer chartplotter-fishfinder units can display AIS targets if they are connected to a receiver. This information is typically transmitted back and forth over a NMEA0183-HS network. This network is 38400 baud, and it is not compatible or slower than the 4800 baud NMEA 10183 system.
Before purchasing any chartplotter fishfinder combination unit, you should also consider cartography. A certain brand of chart card may be available for trade or you might already have it. You will get the best sounder information and, more importantly, fishfinder data from your combo.
A chartplotter/fishfinder combo unit gives powerboaters sailors and fisherman many advantages over purchasing a separate sounder and chartplotter to fulfill their marine electronics needs. Combining a display and a component chassis will allow you to save significant money. This will make it much easier to wire the display up and install it.
Operational learning will be easier as you will only have to learn one unit rather than two. A combination unit can have one downside: You are now collecting all your marine electronics eggs.
