Eagle Cuda 300 Features

eagle cuda 300 portable fishfinder

The Eagle Cuda 300 portable fishfinder comes with rechargeable 12-volt, 8-amp battery and charger; suction-cup-mount 200kHz transducer, suction cup mounting bracket with durable and portable, power pack case. The 800 watts of power allow the sonar to reach down to 600 feet (180 meters). In the owner’s manual it says,, “Actual capability depends on transducer configuration and installation, bottom composition and water conditions. All sonar units typically read deeper in fresh water than in salt water.” But wait, there’s more! It also has hands-free ASP™ operation, Grayline®, Advanced Fish I.D.™ and FishTrack™.  What’s nice is the heavy duty 600-denier water-resistant nylon tote pack which everything fits into with an easy-to-carry web handle. Just pack it up and you’re ready to go! Eagle gives a full one-year warranty on the Cuda 300.

Eagle Cuda 300 Portable Fishfinder Owner’s Manual (pdf file)

Overall, the Eagle Cuda 300 is a great buy for an entry-level fishfinder in the $100 to $200 range. Easy to setup and use, nice display and easily portable from vessel to vessel. An equivalent match-up may be the Humminbird 110 Fishin Buddy or Humminbird PiranhaMax Portable Fishfinder.

  1. Eagle ultra classic portable

    The suction mount was damaged and I need to replace the transducer and mount, are they available to buy.

  2. Fishfinder says:

    The Lowrance HST-WSU 200 KHZ Transom Mount Transducer fits all these Cuda models (since Lowrance makes them too): Cuda 128, Cuda 128 P, Cuda 168, Cuda 168 EXC, uda 240 S/GPS, Cuda 242, Cuda 250 S/Map, Cuda 300 and Cuda 350. However, the transducer alone costs almost as much as the complete unit, so you may want to consider just buying another 300 or other unit which I’m guessing is what Lowrance wants you to do. You may be able to find one cheaper on ebay (see listings above) just to have an extra transducer.
