Deeper Smart Sonars are cold-resistant, and engineered to perform perfectly in winter conditions. Light, wireless and measuring only 2.5in / 65mm in diameter, they fit neatly into any ice fishing hole.
And best of all, there are no long cables or bulky pieces of kit.

New Feature: GPS Ice Hole Marking.

Record and save all the ice holes you fish directly onto a map with the GPS Ice Hole Marking feature. For each new location you fish, a new spot will be marked on your map. Any data your Deeper picks up at that location will also be stored. So, you’ll end up with a detailed record of every hole you fished, which you can use again next time you are fishing that site (the map is available offline). The Smart Sonar Pro+ will use its internal GPS for this feature. For the Fishfinder 3.0 and Smart Sonar Pro the app uses your phone’s GPS, so make sure your phone is as close as possible to the hole you’re fishing when you first put the Deeper in; after a couple of seconds your location will be marked and you can move your phone away.

New Feature: Adjustable maps size.

The Adjustable Offline Maps feature puts you in control of what you see, allowing you to effortlessly tailor your screen display. Now you can decide how much of your display you want the map to take up; simply click the icon and then drag the map across your screen as far as you want. And when you’re done with it, it’s gone in one swipe.

To get started, just drill your ice fishing hole and drop your Deeper in. The device floats on the water so there is no need to fasten it to a line, unless the water stream under the ice is strong. In this case, use the top bolt to fasten your device to a line as a precaution. Then get fishing with your Deeper smart sonar, a must-have piece of kit for any ice fishing enthusiast.

The standard screen has a traditional ice fishing flasher display for monitoring conditions under the ice. And the Amplitude Scope Mode (vertical flasher) displayed on the right-hand side lets you track the movement of even the smallest lure or bait in real time.

The split screen display shows both Regular and Ice Fishing Flasher Modes on one screen. Seeing data from you Deeper transmitted in real-time enables you to follow every underwater movement, including your lure or bait motion and the location of any fish.

The Zoom feature allows you to enlarge the focus area on specific objects on the vertical flasher. This gives you even better real-time lure and fish tracking. This is an extremely accurate tool for monitoring and responding to all the underwater activity. If you spot a fish, use the Zoom feature to maximise observation then target it with your lure or bait.

Using a Deeper Smart Sonar gives you an entirely new experience of fishing on ice. Forget long, wet cables you have to drag around when hole hopping. Deeper devices are small and easily portable – a high-grade ice flasher that fits inside your tackle box or your pocket. For maximum safety, we recommend using the water-resistant soft carrying pouch and attaching this to your belt.

Each Deeper device is fitted with a lithium ion battery, so there’s no need to connect or disconnect your battery after each use. Once your Deeper device hits the water it automatically powers on. Three advanced colour palettes are available when using Ice Fishing Mode – choose the best one based on the brightness and time of day.
