The Striker 4 GPS/Fish Finder from Garmin comes equipped from the factory with the 010-10249-20 dual beam transducer and uses a 4-pin connector. This transducer is 77/200 kHz capable and uses two cone shaped beams. One 45° beam for 77 kHz, and one 15° beam for 200 kHz. If you need to search through bigger depths, you can use the control unit with a 50/200 kHz transducer. That's because it is capable of 50/77/200 kHz. You should also know that the control unit is capable of only using High and Mid CHIRP sonar.

This fish finder will let you scan to a top depth of 750 feet or 228 meters in saltwater. In freshwater, its limited to 1,600 feet or 487 meters. But, this is possible only if you possess a transducer capable of 50 kHz. The transducer that comes out of the box has a top depth of about 800 feet or 244 meters.

The Humminbird HELIX 9 offers a 9” screen; that gives you a couple of great advantages over other fish finders. The first is that the unit is big enough that you can see a lot of information displayed on the screen, but small enough to fit in setups that wouldn’t accommodate larger HELIX units. That’s a fantastic compromise, because the HELIX 9 still has a lot of the display features you’d look for in a fish finder of this size, like the ability to use split screen views. This allows you to display multiple views simultaneously; you might, for example, have the sonar on the left side and the contour map on the right side.

You can adjust the display so that it perfectly suits your needs. When you’re fishing at dawn or dusk, you can adjust the brightness to reduce glare. You can also up the contrast so you can make it easier to tell the difference between strong and weak readouts. You can change the display colour, you can zoom in and out - basically, you can customize this to suit your environment.

There are three different versions of the HELIX 12 offering various options including: the CHIRP model, the Side Imaging + model and the Down Imaging model.

The size of the display on this fish finder well worth talking about. The display is 9” diagonally, which means it’s going to be small enough to fit into most (but not all) setups. The screen is also large enough that you can use combination views while maintaining clarity. For those of you who haven’t used large fish finder/GPS devices, combo views are one of the killer apps - they let you see a lot of information simultaneously. For example, you might use the SideVü, CHIRP GPS, and a map at the same time, so you can get the best picture of the water. You can get up to four different views on screen at the same time, the combinations are customizable, and you can choose whether or not the view is placed horizontally or vertically - it’s one of the better combination views on the fish finder market. All of these features come together to create not just one of the best Portable Fish Finders, but one of the best fish finders overall.
