Understand sonar If you are familiar with how sonar works, skip ahead to the next segment. But, if you have never owned sonar Fishfinder before, this segment will tell you the basic working theory about How sonar works sonar. Based on the sonar technology, the Fishfinder could detect the underwater condition, including fish, structure, or bottom. After you finished the installation of transducer and sonar unit, connect the sonar unit to the transducer.
No Skipping Detection Adopted high detecting technique, your fishfinder has a high detecting distance between 2 sampling points sonar signals precision, which enable a “No-skipping detection”. When sonar works, it continually samples the echo at same interval (for your fishfinder, it is 0.06mS). And the continuous signals form different sampling point.
Dual beam sonar (NAKI 610 / 620 only) NAKI 610 / 610 Fishfinder adopts a 200 / 83(50) kHz Dual Beam sonar system, with which the sonar coverage has a different area of 20°/60° (12°/ 35°)correspondingly, which enable you get the best bottom information. By the Dual beam sonar setting, you can use the narrow 20° (12°) beam to penetrate the deep bottom while you are still being able to use the wide 60°(35°)beam for a wide detection.
Installation Do not begin the installation unless you have read the manual instruction carefully, which contains information critical to the correct installation of your Fishfinder. And for any problems you meet during the installation, please contact your local dealer for help. Packing list Before you install the transducer and sonar unit, please check the Packing List bellow and make sure you are not missing any items.
Tool List (not included) Hand drill, 5/32” drill bits, Phillips and flat-head screwdriver, Pencil Marine sealant. 2-part, slow-cure epoxy (for shoot-thru-hull transducer installation) Transducer Installation Transom installation 1. Select the mounting location When you select a mounting location for the transducer, the flowing should be considered in advance.
holes should be parallel with water surface. Make sure the distance between the bottom of template and the lower edge of the transom is about 0~5mm. distance between the bottom of template and the lower edge of the transom is about 0~5mm (figure-1). c) Using a 5/32” bit, drill 2 holes approximate 1” (25mm) deep at the marked location. Be careful not drilling too deep then 1”. 3. Assemble the transducer a) Slightly spread the pivot and match the (figure-2) transducer to the pivot.
c) Match the pivot to the template (figure-4). Note: Do not push the pivot into the bracket (see figure-5). Do not push the pivot into the bracket (figure-4) (figure-5) 4. Initial installation of transducer a) Apply marine sealant to the 4 x 15mm screws and the two holes on transom. Hold the bracket against transom againˈslightly tighten the template by two 4 x 15mm screws (see figure-6).
b) Adjust the template to make it roughly vertical to the water surfaceˈ then tighten the two screws with Allen wrench c) Press the pivot into the bracket, and then rotate the transducer to make it parallel with the water surface. Note: The pivot match the transducer by ratchetsˈand the increment is12degree, so in some situations you may find it impossible to adjust the transducer completely parallel with the water surface. In this situation a slight incline (1~5degree) is acceptable. 5.
Note Note˖Make sure the cable between the transducer and the first clamp is not tighten. otherwise the transducer cable is easily damaged when adjust the transducer. To avoid this matterˈ please rotate the transducer to the utmost position before tighten the first cable clamp (figure-7). d) When route the transducer cable to the sonar unit, avoid enwinding the transducer cable with other electrical wires or some electrical device that may cause interferencel. 6.
c) Adjust the transducer in a small scope and run the boat at the noted speed (step 2). Then observe the sonar display. If the sonar display is normal, go to the next step. If not, please adjust the transducer until it comes out normal. If by any means a normal sonar display can not be obtained, then it is necessary for you to relocate the position of the transducer. 7.
Shoot-thru-hull installation Transom installation is the most widely used method. However in some situation you also could use Shoot-thru-hull transducer installation, which is more convenient and fast. However, considering of the material of boat and any possible trapped air bubbles in the material, sonar signals will be slightly reduced when passing through the boat hull. 1. Preparation The boat hull should be single layer construction, since the sonar signal could not pass through air.
Chose an appropriate position in the inner hull, then removing the inner layer of fiberglass and flotation materials, thus the surface of outer hull exposed. Epoxy the transducer to the outer layer of fiberglass; press the transducer with a slight twisting motion to purge any trapped air from underneath. After the epoxy cures for 24hours and be certain that the epoxy is solidified, fill the remaining space with resin. And then the installation of transducer is finished.
3. The Permanent Shoot-Thru-Hull installation a) make sure the surface of the chosen location is clearǃdry and free of any oil, then sand the mounting surface of transducer with 100 grit sandpaper until it looks very clean and flat. b) Wipe off the sand debris on mounting surface with a piece of cloth, and then clean the mounting surface of hull and transducer with rubbing alcohol. c) Get a quantity of epoxy and hardener, mix them in a certain proportion and thoroughly, slowly stir them on a paper plate.
Sonar unit installation 1. Find a mounting location (figure-10) When you begin the installation of you Fishfinder, the following should be considered: a) The location should be convenient for your choosing the best viewing angle. b) There should be enough room for the sonar unit tilting & twisting when the installation is finished. For the detailed dimension, please refer to the figure-9. c) There should be enough room behind the sonar unit to route the cable when the installation is finished.
d) To get a stable installation, the mounting surface should be flat enough. Otherwise it will be very hard to fix the lower twist base. And an instable installation may damage your Fishfinder when the boat encounters severe wave shock. 2.
b) Assemble the control head First, put the toothed connector-R into the right position of the back cover.
Finally, insert the locking bolt along the side of toothed connecter, then slightly tighten the locking bolt.
Hold the bracket to the back cover, with the protruding strip (on the bracket) matching the slot (on the bracket). Then press the bracket into the sonar unit. Finally, properly tighten the locking bolt. Then you finished the complete assemble, as following: 3. Fix the Fishfinder on the installation surface which you chose before. 4. Connect the power cable to the boat Your Fishfinder include a 1.5m long power cable, which is used to connect to the transducer and battery.
12v battery (figure-18) Adjusting the viewin 5. Adjusting viewing g angle Your Fishfinder is designed with a tilt & twist structure, which enable you observing the display around 360 degree. When you finished the Fishfinder installation, you could adjust the sonar unit.
locking bolt hold the bracket to twist (figure-22) Note: considering the structure of the sonar unit, the range of adjustable angle is 0~93degree. b) Twist the bracket (figure-23) twist structrue Hold the bracket, twist it slightly, then you could have any angle in the range of 0~360 degree.
