Catching up with fish
What can we learn from this fish finder screen?
This screenshot was taken with the boat slowly drifting due to wind and waves, at a speed of 0.2 knots. We used sea anchor to stabilize our boat. The fish finder was set to transmit at 200 kHz.
Today’s game field was located on a rocky uneven seabed.
The catch of the day was Grouper.
Typically, Groupers are likely to live in rocky reef areas. Using our Bottom Discrimination (BDS) mode makes it easier to find a potential fishing hot spot with knowledge of the seabed structure. Utilizing our digital Fish Finder, it searches out the Grouper and offers high definition clear images, making identifying the game much easier.
This fish finder screen has been shot with ACCU-FISH™ on, so you can see red marks which indicates individual fish and their size (in centimeters).
There are a few individual fish indicated near the border of the reef area, where we see the numbers “46”, “43”, “32”, and “28”. There is a good chance that Grouper might be here. USER TIP: The number “86” might not be a credible number. Additionally there is “12” near the mark, which may indicate that this is a school fish, not individual fish. The Fish Finder misreading the school of fish as a big individual fish is possible. However, if it was not a school of fish, then it might just be a really big fish.
When using ACCU-FISH™,remember that these are suggested sizes and are not necessarily the literal sizes. ACCU-FISH™ offers the best guess of the situation beneath your boat, but it still requires your interpretation to determine what you are really seeing. The more you use it, the better you will get at interpreting the data, which will result in more efficient fishing on your next outing.
