best 9 fishfinder gps combo
The supplied transducer has a transom mounted and comes with a built in water temperature probe as well as a 20-foot long cable. Additionally, the unit features a temperature graph function that displays the difference in surface temperature and water currents under the surface.
Lowrance HDS 9Live Fish Finder offers the most value for money. This fisherman-friendly device is an ideal choice due to its GPS capabilities, large display and excellent mapping abilities. This GPS fishfinder combo has a large display that's easy to use on the water. Lowrance's fishfinder combo is perfect for fishing or just enjoying the outdoors.
You should look for a combo chartplotter/fishfinder that meets your connectivity requirements. You don't have to worry about having the NMEA 2000 network backbone in your older boat if you are not planning on getting it rewired.
When sonar returns locate fish fish, Fish ID displays an icon of a fish. The Flasher sonar function offers a more abstract view that is perfect for ice fishing enthusiasts. Split Zoom allows you to magnify specific areas of the sonar view. The split-screen feature allows you to combine the function with a regular image. The Bottom Lock feature is a sonar-based feature that focuses the sonar and returns to bottom of the water mass.
The solar functions on 83/200 kHz frequencies. Optional XNT9 DB 74T Transducer uses 50/83/200 kHz frequencies. This increases depth capability up to 3,000ft. DualBeam Plus sonar can use both frequencies simultaneously to create images on split-screen and blended displays. The sonar has a coverage area of 60 degrees at 83 KHz. The 200 kHz cone covers a narrow 20 degree area.
By doing so, you can use the high frequency (normally 200 kHz), to read a large area of shallow water and give intimate details of its bottom. It is possible to easily probe the depths by using the low frequency 50 kHz.
Newer chartplotter units that fishfinder units use can display AIS targets if connected to a receiver. These information are usually passed back and forth via an NMEA-0183HS network. This network, which is 38400baud in size, is not compatible to the slower 4800baud NMEA 0183.
