Sonar performance

So Deeper sonars are easier to install and more versatile, but can they compete with expensive mounted units? Josh and George from Pocono Outdoors Guy ran the Deeper Smart Sonar PRO+ and Humminbird Helix 10 side by side. Their findings? For depth, structure and marking fish the 2 units performed the same. As George puts it, “We’ve seen the same things – bait balls, fish, weeds, they all show up perfectly on the Deeper, just as they did on the Humminbird.”

And don’t forget, the HELIX 10 is going to set you back over $1,000 including the mount and cables you’ll need.

Kayak fishing comparison

Deeper Fishfinder compared to Humminbird Helix 7 for Inshore Kayak Fishing

The Deeper PRO is our recommended unit for kayak fishing. It’s light, easy to install with no drilling needed. It has no external battery, so it won’t take up space in your kayak. Best of all, charts for your state are free to download and you can add depth contour data as you troll.

So how does the PRO compare to other popular kayak fish finders? Check out Josh taking it head to head with a traditional boat / kayak unit. His assessment: “I didn’t think it would do as well as a CHIRP unit. I don’t think there was a single mark that I saw on my traditional unit that didn’t appear on the Deeper.”

Here’s how the Deeper PRO stacks up against the Garmin Striker 4cv and Lowrance Hook 4.

The best for ice-fishing

Deeper sonars offer great specs at great prices, with none of the hassle.

ice fishing

We put the Deeper Smart Sonar PRO, our recommended model for ice fishing, up against some traditional ice flashers. We choose three of the best known ice flashers comparable in terms of the price – the Humminbird ICE 35, the Marcum showdown 5.6 and the FL – 18 Vexilar Genz Pack. We say comparable, actually all three are more expensive – the Humminbird costs around $80 more, the Marcum over $100 more and the Vexilar is double the price of the Deeper PRO.

For power and features the Deeper PRO matches or beats the more expensive traditional flashers. Plus, it’s cable free and ultra-light. Most incredible of all, this is a device you can also use in spring, summer and autumn while the ice flashers are gathering dust.

Here are the Top 5 findings

  1. The deepest scanning. At 260ft, Deeper’s scanning depth is only bettered by the Vexilar unit. It scans deeper than the other two.
  2. The best target separation. The Deeper PRO is the best for target separation, offering 0.4”. The Marcum comes close with 0.5”, the other two are nowhere near.
  3. The lightest. Unsurprisingly, the Deeper PRO is by far the lightest, a huge advantage out on the ice.
  4. The only with GPS marking. The Deeper PRO offers GPS functions through the app, meaning you can mark and save every ice hole you fish onto your map. None of the conventional flashers have this function.
  5. The only flasher with a data log. All you sonar activity is recorded and saved, so you can replay the action from all the locations you fished and remember the best spots, all easily accessible on your smartphone. None of the conventional flashers have this function.
