The Hummingbird Fish Finder 325 model is one of the most basic fish finders. It focuses specially on the function of finding fish, without having to many other capabilities. And when it comes to that it really does its job, while the price is also reasonable.
The head unit of this Hummingbird fish finder is equipped with a 4-inch diagonal, monochrome screen, 16 level grayscale, 320 x 240 pixel resolution. Although it’s black and white, it still provides you with a great view of what’s under the boat, pointing out fish, structures, sunken trees, stumps, pits or rocks, measuring depth, your navigating speed and the water temperature.
The Hummingbird fish finder 325 does not have any navigational features, like GPS, chartplotting or trackplotting, and cannot be equipped with a Navionics or LakeMaster SD card. However, since it focuses on finding fish, for that reason it won’t let you down. It does have a DualBeam sonar which can operate on two frequencies:
– 83 kHz – emitting a 60° sonic beam cone under the boat, which needless to say, covers a wider volume of water, but in less detail.
– 200 kHz – emitting a 20° sonic beam cone, which will give you a better image but in a more concentrated are of water under the boat.
Since the Hummingbird Fish Finder 325 has a power output up to 2400 PTP, this makes it quite reliable in waters up to 1000 feet deep. However, don’t forget that a depth finder’s penetration is affected by watertemperature, salinity and frequency, along with the power output.
Like most of the Hummingbird Fish Finders, the 325 model comes with a one year warranty.
