Sonar targets which are not physically attached to the bottom may take one of many shapes. Surface clutter is the layer of water near the surface which is rich in algae and other growth, and often is aerated by wind or wave action. This area of water interferes with sonar transmission and often appears on- screen as regular clusters of individual dots near the "0" line.

Thermoclines are sharp differences in water temperature. These are easily identified by the continuous nature of the return.

A further method of differentiation of fish symbols indicates which of the three sonar beams the fish is detected in. This gives you a reliable indicator of side to side location relative to boat movement. Fish symbols which are hollow are detected in the outside two beams. Hollow fish symbols facing to the right are detected in the right beam and therefore are to the right side of the boat (as viewed from the driver seat facing forward). Hollow fish symbols facing to the left are detected in the left beam, and thus the fish is to the left side of the boat. Solid fish symbols represent fish which are detected in the single center beam, and these fish are directly under the boat.

ID+ adds an additional piece of information to help the user locate fish. On selected fish symbols, the digital depth of the designated fish is drawn to help locate the fish vertically. This is especially helpful in setting bait depths or for downrigger operation.

When a sonar signal is reflected oft the bottom back to the transducer, there is often enough energy left in the signal to be reflected off the surface of the water back to the bottom a second time. Second returns appear as a slightly weaker bottom representation exactly twice the depth of the primary bottom return. The second return is most likely to occur in shallow water and in areas of relatively hard bottom.

The Tour Series uses advanced signal processing to further evaluate any sonar return between the surface and the bottom. For instance, a small school of bait fish usually appears as a dense cluster of individual dots. If the return meets certain additional criteria, a fish symbol will be assigned. There are three different size fish symbols used to indicate the intensity of the sonar return. While signal intensity is a good indicator of relative fish size, different species of fish have different sonar characteristics, so it is not always possible to distinguish fish size between varying species. The signal intensity is "normalized" for depth so that a small fish close to the boat does not appear as a large fish symbol.

The Tour Series uses a simple 5-button keypad for all user input. When any button is pressed, an audible "chirp" confirms the control input. In the event that a particular button has no function or is inappropriate for the situation, an audible "error", or multiple chirps, will be heard.

Tour Series specifications

The Humminbird Tour Series stands out as a premier line of fish finders and sonars, designed specifically for anglers seeking advanced technology and durability on the water. Renowned for their high performance, the Tour Series incorporates cutting-edge features tailored for serious fishing enthusiasts.

One of the hallmark features of the Humminbird Tour Series is its superior imaging capabilities. The series boasts the latest in sonar technology, including Side Imaging and Down Imaging, which provide incredible detail and clarity below and beside the boat. This advanced sonar allows anglers to identify fish, structures, and underwater vegetation with unmatched precision, transforming the fishing experience into a more strategic and informed endeavor.

Another significant attribute of the Tour Series is its GPS capability. Equipped with Humminbird’s proprietary LakeMaster and Navionics maps, these devices allow users to navigate with confidence. The integration of GPS also enables the creation of custom waypoints, routes, and tracks, enhancing connectivity to fishing hotspots. The AutoChart Live feature lets anglers create real-time maps of their fishing spots that highlight depth contours and bottom hardness, offering a customized view of their fishing environment.

The Tour Series is built to withstand the demanding conditions of fishing. With a rugged design and a bright, sunlight-readable display, these fish finders ensure visibility in various environments. The touchscreen interface is intuitive and responsive, allowing for easy adjustments on the fly. Additionally, the models are equipped with a robust transducer system that can achieve impressive depths and deliver accurate readings even in challenging waters.

The integration of the 360 Imaging feature is another standout characteristic. This capability offers a complete panoramic view of the water around the boat, providing additional data on fish and structure location. The ability to see a complete picture of the surroundings allows anglers to make better decisions in real time.

Lastly, the Tour Series doesn’t compromise on connectivity. With built-in Bluetooth and networking capabilities, anglers can connect multiple devices simultaneously and share data seamlessly. Whether you are monitoring multiple fishing rods or collaborating with fellow anglers, the Tour Series provides the tools necessary to enhance your fishing excursions.

In summary, the Humminbird Tour Series combines advanced sonar technology, comprehensive GPS mapping, durable construction, and connectivity features, making it a leader in the fishing electronics market. For passionate anglers, it delivers not just tools, but a profound understanding of their aquatic environment.
