What's good
- You watch a walleye approach, inspect and eat a jig, in real time, out to 80 feet
- Forward mode turns searching from guesswork into looking
- Works through the ice with a pole mount, which is transformative on Saginaw Bay
- Plus version resolves individual fish in a school where the original blurred them together
What isn't
- Total system cost with a compatible head unit and trolling motor mount is well over $2,500
- Real range is closer to 60 to 80 feet than the advertised numbers, and it degrades fast in a chop
- The learning curve is steep — most people fish worse with it for the first month
We list the drawbacks because a recommendation with no downside is a sales pitch. If a cheaper item does the job on your water, the write-up says so.
