Welcome to IDO
I would say confidence. Let me explain. The single most important factor in determining an anglers success most always revolves around the confidence in which they utilize their equipment.
In the case of sonar as per this thread; Humminbirds “SI” is no different. Anglers soon learn how to define fish by the shadows they leave on you “SI”. IMO equally important as defining fish is the finding of fish relating structure. Using the side imaging in conjunction with your lakemaster chip allows you to have a starting point for your search. Case in point; If I recognize an inside turn with a nice feeding shelf on my Rainy Lake chip I may search that surrounding area for the coveted “Spot on Spot”. Maybe there is a small rubble pile sitting off deep or even shallow yet in close relation to seemingly a fish magnet. By utilizing the Side Imaging I will note an irregular piece of structure that I will drop a waypoint on. I will then come back on the way point in 2D to see if that piece indeed holds fish. It might not at that very moment……..Might not tomorrow, but MIGHT BE STACKED the next!! The ability of fisherman to effectively side scan in addition to our ability to view with confidence in 2D will further enhance our ability to locate not only structure, but also fish. Remember while in the Split screen mode with your Humminbird; one side of the screen will be active at a time. If you wish to zoom in on something or stop the screen on your SI simply arrow over to your point of interest then zoom it in.
Here is just one other fun, and very rewarding way to use your side imaging. I often like to deal with something I know. Say for example your searching a small island. Most anglers realize certain spots visually on the shoreline that will likely hold fish. What 99% of anglers will not realize are the better spots not visable to the naked eye off the island. Possibly these are the spots the fish hold when they are in a more nuetral mood or the sun is high. Keep your boat 150-200 feet off the island. Try keep your “SI” directly facing the shoreline. Now take your “SI” and do either a Right side only or Left side only. circle the island slowly paying particular attention for under water ridges or isolated rock piles. Note to Self……….MARK THEM and TELL NOBODY!! You now have uncovered first holding structure nearly 99% of anglers have no idea exists.
If an angler were to do these 2 things alone I assure you the investment in Humminbirds Technology would seemingly be priceless. Still many anglers fear change. Possibly they simply don’t understand it or fail to invest the time to learn how to use it.
This is truly the tip of the iceberg, but a starting point for beginning to take advantage of the major advancements from Humminbird. Greg at the SBC is a “WIZARD” when it comes to utilizing the units. He has taught me more than I can put in words here. I highly recommend guys wanting to upgrade units to visit the Skeeter Boat Center. I buy my Humminbird units from them without hesitation. They do a simply wonderful installation job which is NOT an expertise of mine. They also provide anglers some a 101 on getting the most out of the HB line.
I too am still learning. I do however realize this tool will greatly increase my knowledge of the underwater world. These units can be as easy or as complex as you make them. I have my 3 pre-sets on my 1198C. I know them and understand them………AND USE THEM A LOT!!
