As an angler, a quality fish finder can make fishing trips much more rewarding for you. Unfortunately, most fish finders on the market cost a fortune. For those who can’t afford to spend thousands of dollars on a fish finder, the Humminbird 4090301 386Ci Combo is something to consider. Despite its slimness and small size, it is jam-packed with advanced technology.


The Humminbird 4090301 386Ci Combo features the Color Fest display. When you first turn on this device, the main thing you will notice is how high the display of this fish finder is in both resolution and contrast.

The resolution of the Humminbird’s screen is 320 x 240 pixels, which is quite impressive when you take into account the device’s size. Diagonally, the size of the screen is just 3.5 inches. While this may turn you off initially, particularly if you’re accustomed to fish finders with larger displays, you’ll find that the resolution more than makes up for the small size.

When it comes to the color, the display of the Humminbird 4090301 386Ci Combo supports 256 Color, which is a feature that is not shared by most fish finders.

The high resolution and contrast of the Humminbird display ensure that you’ll find the screen both clear and very easy to read. Due to the amazing clarity of the screen, you may find it easy to forget all about the small size.

SwitchFire Sonar

The Humminbird 4090301 386Ci Combo DualBeam fish finder utilizes the SwitchFire Sonar to give you a highly detailed view of just about anything and everything below your boat. The great thing about the SwitchFire Sonar is that it gives you a choice regarding how you want your sonar returns to appear.

The SwitchFire Sonar features two distinctive display modes, both of which allow you to adapt to ever changing fishing conditions quickly and efficiently. You have the option to add or remove various details, monitor turbulence, and temperature, and to account for water depth. You even have the option of experimenting with various lure presentations. The two modes are clear mode and max mode.

The clear mode allows fishermen easy viewing in the roughest of waters. It also allows you to filter out the noise found in shallow waters. This will give a much clearer image of the fish below. This mode is excellent for those who don’t want to deal with unimportant details. For example, it eliminates any interference you may experience due to suspended particles in the waters. The max mode is good for those who are detail-oriented. This mode allows you to see fish, structure, cover, water currents, and even thermoclines. The max mode is especially useful for easy lure monitoring.


One has two options for mounting when it comes to the Humminbird 4090301 386Ci Combo. There is the quick disconnect or the in-dash. The quick disconnect option allows you to remove the fish finder from the boat quickly and efficiently. However, based on the experiences of many, after a few years, the mount will fall apart, leaving you little choice but to buy a replacement. The in-dash option allows you to install the fish finder unit into the boat’s dash. This is a good option for those who want a more integrated appearance. The fish finder comes with the transom mount transducer included.


Despite this Humminbird’s small size, this fish finder has plenty to offer to fishermen. The display is very colorful and of pristine clarity, and the technology of the SwitchFire Sonar, the internal GPS, and the UniMap do not disappoint. Overall, the Humminbird is something to consider for the anglers out there who want a quality fish finder yet don’t have one grand to spend on one.
