Full Review
The Humminbird Helix 7 CHIRP MEGA SI+ is the most capable fish finder you can buy under $500. Side imaging is a genuine game changer for finding brush piles, drop-offs, and fish-holding structure that you would never see with traditional sonar alone. The learning curve is real, but once you understand what you are looking at, this unit will put you on fish that other anglers are driving right over. It is the best imaging value on the market.
