## Customer Reviews

### ⭐⭐⭐⭐⭐ Fishing must have
*by K***R on February 27, 2024*

My husband has started fishing this past year and was told he needed this now he is telling everyone to get one

### ⭐⭐⭐⭐⭐ Easy to install
*by J***N on December 13, 2023*

Great product and easy to install

### ⭐⭐⭐ OEM Product
*by A***R on February 24, 2025*

OEM Transducer. I had to return the first as it was cracked. I am not sure if it would have affected the functionally or not. Replacement was in good shape and works well. Installation is as easy or as difficult as you want it to be depending on how you want to route your wires.
