|Adjust the Sensitivity:|
There are 4 user selectable sensitivity settings to choose from. So, which setting is the right setting? It greatly depends on the clarity and/or depth of the water. Very clear water allows for a moderate sensitivity setting. Conversely, dirty water requires a higher sensitivity setting to target detail but will increase the irritating false readings. Targeting deep water fish generally requires greater sensitivity, especially in stained or dirty water. Salt and brackish water also require a comparatively higher sensitivity setting. While this analysis may seem confusing, the concept is simple. As the unit's sensitivity is elevated, a broader view and smaller details show on the screen. But, with a broader and stronger view comes more clutter and debris. The clearer the water, the less sensitivity needed to get accurate details and vice-versa.
|Use the Fish Alarm:|
The F33P has a built in fish alarm. Turn it on, and when a fish passes under the sonar sensor, an audible alarm will sound. You can then use the fish depth scale to drop your bait to a depth that will get it in front of the fish.
| Maximize Side-Scanning|
| Here are some ideas for maximizing the usefulness of the Side Scan Adapter: ~ Attach it to a dock piling and scan sideways for fish swimming by. ~ Attach it to a boat, kayak, or canoe hull and slow troll for fish, all the while keeping a look out for fish behind or in front of you. ~ Attach it to a broom stick handle and search for the best fishing location. ~ Attach it to a broom stick and seek out the fish hiding away from your fishing hole while ice fishing. .|
| Broom Stick Side-Scanning|
By attaching the Side Scan Adapter to an ordinary broom stick or paint roller handle purchased from a local hardware store, you can scan for fish suspended in the water column within 99.9 Ft (30.4 M) of your location. Attach the sensor to a handle, lower the sensor into the water as per figure 10, and slowly move the sensor in a manner that will allow the signal to search the desired location (a sweeping motion similar to using a flashlight is most effective. Keep in mind the sonar signal is emitted from the base of the sensor. Scan down, sideways, or any combination of the two. Remember, to get depth and bottom contour and composition readings you will have to aim the signal at a solid object within 99 Ft (30.4 M), however FISH readings will be accurate, even if the depth readings is ---.
| Uncover Ambush Locations|
There are a host of reasons for fish to be in the weeds. The weeds are a constant oxygen source, which attracts baitfish and crawfish, which are food for a lot of fish. Weeds also offer a place for the fish to lie in ambush, waiting for an unsuspecting meal to pass by. And in fairly dense masses, weeds offer shade from the blaring hot sun. If the fish that you are targeting prefer a weed habitat you should try to fish your bait as close to the top of the weeds as possible (installing a weed guard on your hook will prevent accidental snagging of the weed). If the fish are not active, simply slow down your presentation and wait for the fish to come to you.
| Uncover Ambush Locations|
Experienced fisherman will tell you that many fish choose to hide along the bottom and ambush their prey as it swims by. Logs, Tree Stumps, Rocks, Ledges, etc. all provide excellent ambush locations. These locations will be shown your fish finder display as a series of "rock" indicators. The more rock indicators, the more ambush locations there are. Uncovering these hiding places will prove invaluable to your fishing trips. Remember to keep an eye on the depth of your bait while fishing bottom structure as you do not want to snag it on the structure. .
|Bottom Structure Fishing|
If your targeting fish that prefer weed or structure try this: If you're fishing from a boat establish accurate readings by using the techniques in this manual. Next, slowly move the boat around the fishing area while paying close attention to the bottom structure and Weed ID. Do not begin fishing until you discover the optimal spot for fishing (using your knowledge about the desired preys feeding habitat and the fish finder readings). This may take a considerable amount of time, but if you find a secret spot it will be well worth it. This can also be done from shore by walking along the bank and tossing and retrieving the sensor out into the water in 5 foot intervals. IMPORTANT: When you find that secret spot, keep it to yourself. There is nothing that ruins a secret spot quicker than word of mouth.
|Don't Forget to Fish Shallow|
We've all been brought up with the notions of casting to visible cover. This makes non-visual targets difficult to fish. The number one thing to keep in mind when fishing deep water is structure is king. Structure is the actual bottom contour (breaks, drops, humps, etc.) Do Your Homework: Get contour maps of your favorite fishing locations. Search for structure, either main channel, secondary creek channels, ledges or breaks. The key areas are anywhere these channels intersect with something - a point, hump, land mass, or anywhere they make a dramatic turn or bend. These are the type of areas you need to look for. When you first arrive to the location you have mapped out fast idle the area in a zig-zag pattern while watching your fish finder for structure.
