In nutshell, the Echomap PLUS line is a step above the Helix. (I own some Helix’s).
The screen is crisper.
The detail is better.
It’s more intuitive.
It has a Touchscreen, which is awesome for changing settings on the fly. A “pinch and a flick” changes your zoom size and zoom area in 1 second. No need to hit buttons and go into a menu.
You just raised a fish out of your zoom range? No problem. Simply slide your finger on the screen, that’s it.
Fishing side by side with a Helix, my buddy would struggle finding his bait in weeds, I have no problem.
The ability to add Panoptics.
It has Favorites buttons (like the Helix) that are extremely handy.
Overall more refined and advanced. It has WiFi and Bluetooth to connect to your phone for updates etc.
Not that you need or want it, but you can even have your text messages pop up on the screen lol
It’s next level schitt….and for the same or less money (less than $600 online for a 7″ Plus)
I’ve used it it 5′ of water with weeds, to over 200′ with solid rock bottom. It flat out performs.
Make sure to look at a “Plus” unit. If it doesn’t say Plus, it doesn’t have the touchscreen/wifi/Bluetooth.
About the only thing I think is better about the Helix, is the ability of using Lakemaster. The Bird is a nice unit (not bashing them at all), but an Echomap plus is simply better.
The Helix is more on par with the features of a Garmin Striker series, which are even less money yet. They offer a 5″ ice bundle for around $300.
