Summary of Contents for Humminbird NS25
- Page 2 Units will typically read deeper in fresh water than in salt water. After spending a few minutes with your NS25 on the water, you will see the unit’s ability to accurately portray the underwater terrain, suspended targets, GPS position, and your position on a map.
- Page 3 GPS “Y” cable for NMEA output and GPS receiver input Publication kit In-dash mounting kit It is recommended that you install the NS25 components in the following order; 1) GPS receiver, 2) transducer, 3) card reader, then 4) control head. GPS Receiver Installation To optimize performance of the GPS receiver, mount it in an area that has full exposure to the sky.
- Page 4 Under Location Access with Deck More Than 3/8” Follow these steps to deck mount the GPS receiver routing the cable down through a thick deck: 1. Determine the best location, then route the 20 foot cable from control head to the mounting location.
- Page 5 5. Preassemble the flange, mounting bolt, and gasket with the GPS receiver, routing cable through all components; tighten GPS receiver until its base is in contact with the gasket. 6. Secure flange with #8 x 5/8 flat head screws. To access all screws you will need to rotate the GPS receiver.
- Page 6 Customer Support section. INSTALLATION OVERVIEW Your Humminbird fishfinder consists of two primary components to install: the control head and the transducer. The control head contains the sonar transmit and receive circuitry, as well as the user controls and display.
- Page 7 INSTALLATION PREPARATION Determining How to Mount the Transducer Your Humminbird fishfinder includes a standard transducer. This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat. The transom installation, which is the most widely used, places the transducer on the outside of the boat hull.
- Page 8 ALTERNATE MOUNTING METHODS ALTERNATE TRANSDUCERS AND MOUNTING METHODS Your Humminbird fishfinder comes with everything necessary for installation and operation on most boats. However, there are several situations which may require a different type of transducer. Inboard boats, wood or metal hulls, and sail boats create unique transducer mounting needs Alternate transducers and mounting methods are detailed below.
- Page 9 BEGINNING INSTALLATION Now that you have determined the transducer mounting method you can begin installation of your new Humminbird fishfinder. The installation guide included on the next few pages provides detailed step by step instructions for installation of the control head and transducer. For transom mount transducer installations you will need the mounting template included with your manual.
- Page 10 Do not begin this transducer installation until you read the Installation Preparation in the Operation Guide. This chapter contains information critical to the correct installation of your transducer. Due to the wide variety of boat hulls, only general instructions are presented in the installation guide.
- Page 11 If the propeller(s) is (are) forward of the transom, it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered. Step Two - Drill the Mounting Holes 1. Remove the mounting template from the front of the Operations Manual. 2.
- Page 13 Step Four - Mount the Transducer to the Transom 1. Apply silicone sealant to the mounting holes drilled into the transom. 2. Align the transducer assembly with the drilled holes in the transom (Figure 8). 3. Use either a flat head screwdriver, a 5/16" (8mm) hex driver, or a 5/16" (8mm) socket to mount the assembly.
- Page 14 mounting bracket. Drill this hole and install the screw after final testing and adjustments have been completed.
- Page 15 If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50' (15 m). Call Humminbird Customer Support for more information. Follow these steps to route the cable through the transom: 1.
- Page 16 Inside the hull mounting generally produces good results in single thickness fiberglass-hulled boats. Humminbird cannot guarantee depth performance when transmitting and receiving through the hull of the boat since some signal loss occurs. The amount of loss depends on hull construction and thickness, and the installation.
- Page 17 The transducer cannot transmit through air. The water purges any air from between the transducer and the hull and fills any voids in the coarse fiberglass surface.
- Page 18 3. Power up the Control Head. 4. Run the boat at various speeds and water depths while observing the screen on the Control Head. If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer needs to be moved. If depth performance is required, test the fishfinder in water at the desired depth.
- Page 19 CONTROL HEAD INSTALLATION Step One - Determine Where to Mount Begin the installation by determining where to mount the control head. Consider the following to determine best location: The cables for power, transducer and temp/speed accessories (if applicable) should be installed first and must reach the mounting location. Extension cables are available.

- Page 25 Card Reader Installation The card reader has two mounting options. You may mount it on a vertical or horizontal flat surface, or you may mount it in-dash in a dry area. The card reader is not waterproof. Take this into consideration and follow these steps for surface and in-dash mounting.
- Page 26 The NS25 cannot recognize a C-Card if it is not properly placed in the card reader. To place a C- Card in your card reader, gently insert it face up with the gold plating facing downward. The C- Card and the slots on the card reader are keyed for correct insertion.
- Page 27 CAUTION: Some boats have 24 or 36-volt electric systems. Be sure your NS25 is connected to a 12 VDC power supply. If you must wire the NS25 directly to a battery, be sure to use the in-line fuse holder and 1.5-amp fuse provided for the protection of the unit. Hummingbird is not responsible for over-voltage or over-current failures.
- Page 28 Drilling the Mounting Holes After you have determined the best mounting location for your control head, proceed with the following instructions: 1. Depress the latch on the rear of the unit and separate the unit from the mounting bracket. 2. Set the mounting bracket on the mounting surface. 3.
- Page 29 NOTE: If the cables must pass through the mounting surface at a different location, drill the 1” hole at that location and pass the cables through from underneath. Also, you must break out the wire slots on the rear of the mounting base using needle-nosed pliers. 6.

- Page 47 Using the Routes Menu You can create and travel permanent routes through the options in the Routes menu. See “Using the Menu System – Routes” section for more information. On-screen Navigation Information When traveling a route additional infoboxes appear at the bottom of the screen to provide navigation information to the destination waypoint.
- Page 48 Flag symbols mark each waypoint in the route. “S” designates the starting waypoint, and each following waypoint is marked with a number showing the sequence. The final waypoint is designated with an “E”. Selecting a View for Navigation When traveling a route, navigation information appears on the North-Up, Course-Up, Combo, Sonar and Numeric Views.
- Page 49 The Course-Up view orients the map with the direction of travel at the top of the screen. This is useful during navigation as the map and course projection line movement closely relate to corrections made to the boat’s course. When used at the more detailed map ranges, the proximity of the course projection line to the track line indicates how accurately the course is being followed.
- Page 50 Waypoint Sequencing as you move beyond a destination waypoint within the route, the NS25 automatically “sequences” to the next waypoint providing new navigation information. At times, the NS25 may not be able to determine when to automatically sequence to the next waypoint. When this occurs, a menu displays to permit manual sequencing.
