Other factors will be the size of the fish you will be in pursuit of and the typical cover on which you will fish.There is a tendency to start fiddling with the sensitivity and contrast as soon as you get on the water, but everything is best left at default until you have the time at the wheel below your belt. In addition to regular depth sounding the EA400 Hydrographic Echo Sounder can now be employed for side looking sonar surveying. A short press will just lay down a waypoint. The majority of SI sonar could be operated at two frequencies of 800 kHz and 455 kHz. Side scan sonar is used to image ocean, lake, or river bottoms. But using the SI model, clear pictures of where the tree branches really are will be displayed, putting you in the know as to where fishes are and are not hidden.Actually, the proper keyword is ease of accuracy. On a normal 2D Sonar, any large object will only show up as a color-blob, varying in color, dependent on its softness or hardness. Side imaging models are known to contain an operator-friendly point-and-click feature which lets you mark the location and related statistical calculation of those underwater object that peak your interest. This means that with the included transducer, the unit can use Mid-Range CHIRP for its standard sonar. The internal GPS is slightly enhanced, providing more accurate position readings when compared to existing models. As well, sonar images, be them 2D or CV/SV, possess much less clutter. This is, nevertheless, made up for by its ability to cover more water at a given point in time, all accolades to the greater amount of water they scan.Both of the imaging technologies excel in different ways. In this light as well, they will continue to produce you reasonable and relatable images, even while you are boat-traveling on high speed.
That said, what is particularly confusing as an aspect of fish finders, is that many anglers tend to struggle in understanding the direction in which each product emits it sonar waves. Speed, which is the scroll speed of the side images, should be left at a default speed of 5 when idling between 3 and five mph.You can then do an up-or-down adjustment to match the speed of your boat.
For instance, using traditional sonar imaging, the branches of a sunken tree might appear as a fish and return to be elusive to you. These fish finders also are not built to provide a defined image of things below your boat, probably leaving you in the wanting of a down-imaging model if you are downright interested in learning of what specific piece of cover that lays beneath your boat.Also, as have been said earlier, side-imaging depth finders only work with slower-speeding boats, making it hard to use when you are trying to reach some other potential ice fishing locale.
Added to that complication is trying to understand how SI technology works and knowing exactly what it can do for you. What you need to consider is the depth you will be fishing and the speed at which you are most likely to travel around the boat before finally coming to a decision. The sensitivity and contrast help you adjust the brightness ratios between light and dark colors. Better still, the transducer can incorporate a water temperature sensor; at this moment, being a unit that can indicate the temperature of the top-layer water. As a matter of fact, there are some units that rely on both types of imaging and allow you to opt between the two. Regarding its depth capability, the DualBeam Plus reaches a whopping 1500 feet, and the side and down imaging can both reach 100 feet. All Rights Reserved. They offer much better point-of-view than the other sonar imaging does. Drive past visible objects such as bridge pilings, rocks, boat ramps and grass beds just to begin learning what the beneath-the-surface objects look like in the side view.Preferably, run side imaging while at speeds between 3-6 mph for the best results.
