Humminbird PiranhaMAX 150 Waterproof FishFinder Review

Humminbird PiranhaMAX 150: I’m always amazed at the products from the Humminbird Manufacture. Don’t let the low price fool you or keep you from taking a good look, this little baby has all the features you need to find the big ones where you fish.

It has many features you would expect to find on the more expensive models out there. Don’t let this one get by without at least looking at the review. I think you will be pleasantly surprised.

  • Fish ID+ interprets sonar returns and displays Fish Symbol when requirements are met

Fish ID+ uses advanced sonar processing to interpret sonar returns and displays a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Three different fish icons represent the intensity of the sonar return, and provide an indicator of relative fish size.this is amazing technology.

  • Users of this Hummingbird Fish finder are commenting on the ease of use and the great price.
  • Another tells of an easy Install which makes me happy.


  • One user says it is hard to see the screen when the temperature goes above 90, Actually above 90 and I’m home in A.C. lol

I honestly feel this is a very nice unit with a lot of features found on only expensive models and would have no problem recommending this to a friend.
