A Premier Combination Head unit and probe. The Speed-N-Temp Sensor operates as part of the Bottom Line NCC and Cannon Mag 20 DT System. The Speed-N-Temp� Sensor senses the speed and depth of your lure and the water temperature and light level at your lure and displays the information using large, easy-to-read numbers on the screen of the Tournament NCC 6300. Sensors measure the information once a second to making it easy to find best place put your lure. The Speed-N-Temp Sensor uses the downrigger cable to transmit the data up to the NCC 6300, so no extra or monitors are needed. And, the Speed-N-Temp Sensor can operate for up to 200 hours from one 9-volt battery. The new Speed-N-Temp� Monitor from Cannon has its own monitor for use with any downrigger on the market. Simply attach this informative accessory to any manual or electric downrigger and unlock the mysterious secrets of dark and deep trolling waters. The sealed underwater transmitter attaches to the cable of any downrigger just above the weight. The sensors on the Speed-N-Temp Monitor register the absolute depth of the lure and the lure�s true speed as well as light intensity and water temperature at the lure's trolling location. These readings are then electronically transmitted up through the downrigger cable and digitally displayed on the Speed-N-Temp Monitor. Absolute depth of lure eliminates blow-back estimations and calculations that anglers normally must decipher. While the boat may be traveling at 2.5 mph, the lure may travel at different speeds depending on underwater currents. With the Speed-N-Temp Monitor, true lure speed in tenths of mph can be adjusted by the angler providing optimum strike stimulation. A chartreuse and blue lure looks great in the sunlight but at a depth of 80 feet with filtered light the lure may look invisible to the fish. Speed-N-Temp Monitor measures light intensity and the appropriate lure color can be selected for the conditions at the trolling depth. Water temperature at the lure's depth is provided, crucial for tracking temperature sensitive fish. Using a standard cable, the Speed-N-Temp Monitor operates up to a maximum depth of 100 feet. A coated cable increases operation depth up to 300 feet. Speed-N-Temp activates when the speed wheel enters the water and automatically shuts off after 15 minutes of inactivity. A replaceable 9-volt battery powers the transmitter for up to 200 hours of operation. Battery voltage is also digitally displayed on monitor screen. The use of Cannon's Speed-N-Temp Monitor will not interfere with downrigger features such as Short Stop, Positive Ion Control and Stacker Releases. The 7.2� square inch screen, with 2,300 pixels per square inch, provides an easy-to-read display of the transmitted information. Overall, the saltwater protected monitor measures 5 inches by 5.3 inches by 2.5 inches and can be easily mounted at any location on the boat. For the look of factory rigging, use the optional installation bracket and mount the monitor in the dash of the console.
