[QUOTE="SilverFox, post: 3520621, member: 9102"] SI is much better utilized when placed at the console. Your best picture/image is going to be obtained at speeds higher than most people run their trolling motor... It's also hard to keep the trolling motor running a straight line. Any movement left or right is going to decrease image quality. I find what ever cover/structure or schools of fish I want to fish with my side image unit on the console. I then mark it on gps with a waypoint. My SI unit is linked to my front unit and I position the boat using that waypoint and fish it then. I already know what's down there... And with greater detail since I was moving at speed and in a straight line when I saw it. If you're set on using a SI image up front, it can be done. Humminbird units allow you to increase or decrease the chart speed which allows you to fine tune the image. I run my chart speed around 4-5 according to conditions. My boat idle speed is 3 mph. A good rule of thumb is idle speed plus one. If on the trolling motor where your speed is lower normally... And your off and on the button, it's hard to match that chart speed up with the actual speed of the boat. Most people I know use a chart speed of 1-2 when doing this. I have a Hummnbird SI/DI unit on the console and a Humminbird 2D/DI unit on the bow. This works well for my style of fishing. There are Humminbird forums and also a forum on the BBC board that there are pretty educated guys posting on... Some actually work with Humminbird. They are just releasing the new model units now. It's a good time to purchase if you're not afraid of buying the older technology. There are some deals to be had. BBG marine is a great place to buy also. Brian is very knowledgeable about the units and usually has the best prices around. He is located in Georgia. bbgmarine.com is his website. It's best to call him for pricing. Sometimes the actual price is cheaper than the one posted since he is not a big box store the price changes often. [/QUOTE]
