S4Part: BASIC ELECTRONICS ettings
Today, most fish finders are user friendly and fine tuning your unit can make it even more useful. There are many ways to do this.
The best way to customize your unit is to try different settings and displays until you get what you want. If you did something you don’t like, or your unit goes crazy, re-set it to the factory (default) settings. Read the manual and learn how to do it. It will save you hours of frustration. (On Garmin units you reset it through “System Setup”).
The factory defaults on most fish finders will give you adequate performance. But there are a few things you might want to do to make it better. 1) The biggest mistake we as anglers make is not to display the battery voltage, why? All your electronics are running from your cranking battery. I got my voltage a alarm set with a very annoying alarm if the voltage drops too low. You don don’t want to sit with a winning bag an and the outboard doesn’t want to st start. Also the aerator can’t supply o oxygen rich water to the livewell.w If the alarm goes off you still have the tim time to run theth
outboardoutboar and charge the battery. (Low voltage is anywhere below 12V) 2) I like to display water depth, live-well temperature and water temperature in numerals. You might want to add trip distance and perhaps speed over ground. Any of these overlays on either the map, or the sonar page. Resize and move the display that works the best for you. 3) Start with the fishing trip by setting your finder to auto mode. Doesn’t matter what conditions the water is, even if there is a lot of clutter or suspended solids around; auto mode will give you normally the best starting point. 4) Clutter can frustrate many anglers. When so, activate your STC (Sensitivity Time Control) which basically acts as a short-range filter. This normally will get rid of the jargon (unintelligible language), which is typically the effect of air bubbles close to the surface (created by turbulence from your boat).The clutter is not a bad thing. Sometimes it is huge amounts of algae or plankton that forms the base of the food chain for the bait fish. When there is a big change in surface clutter it can be the barriers between different water masses. Where there is food, there will be bass. 5) Sometimes you have to manually adjust the settings and down turn the sensitivity because of too much clutter on the screen. Turn the sensitivity all the way down until you only see the bottom, but bear in mind that turning it down from this point may also do away with weak returns created by small fish, vegetation, and other items. Be careful not to over tune the sensitivity. You still want to see faint lines that appear at a constant depth. This can be the thermocline that will form between different layers of cold and warm waters. On the colour units the
