Similar to the Fishin’ Buddy MAX DI, the Fishin’ Buddy MAX model is one of the discontinued Humminbird fish finders. It’s a sonar-only unit offering only DualBeam sonar. It does not have a GPS plotter or charts, nor it is compatible with any. For reference, this is the Humminbird part number 410050-1.

Sonar and transducer
As opposed to the Fishin’ Buddy MAX DI, this unit doesn’t have Down Imaging sonar. It only has DualBeam sonar, capable of two frequencies, 200 kHz, and 455 kHz. The transducer supplied with it is also a basic one, the XP 9 28 T, a transducer that doesn’t include a temperature sensor.
Since the unit’s sonar is only DualBeam and not DualBeam Plus as for the HELIX 5 CHIRP GPS G2, it can only use one frequency at the time. It also doesn’t have CHIRP technology. However, it still provides a decent target separation, keeps track of the bottom and helps you identify the fish targets.
The transducer uses two conical beams, one of 16° for 455 kHz, and one of 28° for 200 kHz. Its maximum depth capability is 600 ft (183 m). Also, the recommended speed for the clearest images is between 1-6 MPH.
Since the Fishin’ Buddy MAX doesn’t have DualBeam Plus sonar, it also does not have the SwitchFire function. However, it does share several useful sonar functions with the other, more inclusive units. These are the Selective Fish ID, three types of alarms, and Structure ID.
Structure ID is a function that represents the weak returns as light pixels, while the strong returns will be darker. And finally, there’s also a WhiteLine function which highlights the strongest sonar return in white, resulting in a more distinctive bottom contour.
Selective Fish ID is a sonar function that replaces the fish arches with fish icons. Each fish icon will also have its current depth displayed next to it. However, not all the fish icons shown will actually be fish. The feature interprets most of the suspended targets as fish and will assign a fish icon to them.
Finally, the unit’s three alarms are Fish Alarm, Battery Alarm, and Depth Alarm. For the Fish Alarm, there are 3 fish size options such as “Large, Medium and Small” and you can choose one of them or all so that the unit will sound when it detects a fish that corresponds to the setting. The Battery Alarm sounds when the battery voltage is equal or less than the menu setting. The Depth Alarm will sound when the depth is equal or less than the selected value.
Control unit and mount
The Humminbird Fishin’ Buddy MAX comes with a different type of mounting kit than other units. The unit itself has a tilt and swivel mount, but this mount is designed to attach to the included 24″ (61 cm) pole. The pole is fixed, not telescopic as for the Fishin’ Buddy MAX DI.
The control unit features a color display with a 256 color range, 3.5″ diagonal, with a pixel resolution of 240H x 320V. It has LED backlight with 5 levels of brightness which considerably improves its readability in direct sunlight. It requires 8 AA batteries which are not included.
Also, it has excellent waterproofing, but when in contact with saltwater it’s recommended to wipe the unit immediately, as salt may eventually corrode its connectors.

The Humminbird Fishin’ Buddy Max is a sonar only fish finder, featuring DualBeam sonar. It can use two frequencies, 200/455 kHz, being capable of scanning depths up to 600 ft, which means you can also use it off-shore if you remain in the shallow waters. The unit includes the transducer and a fixed pole for it, along with a mounting clamp, which is easy to install on most fishing boats. With a little improvisation, it can also be mounted on a buoy for ice fishing or stationary fishing. In all, it’s a versatile and affordable fish finder.
