The brand

Deeper is a Lithuanian brand specialising in portable sounders that includes Deeper start, Deeper Chirp+, Deeper Pro and Deeper Pro+. Deeper Start is the easiest to use, smallest and lightest of these models.

Deeper Start

Deeper Start makes it easy to use a sounder to spot fish, map and save fishing spots, even when it's not usually possible.

Deeper StartLightweight (65g) and easy to carry, self-contained, with a minimal footprint, it fits in your pocket.

With the Fish Deeper app, you have access to information on depth, bottom type, fish presence and water temperature.

The Fish Deeper app is a great way to keep track of the depth of the water.


Who is it for?

Just because you're fishing from shore, a dock or a bridge, doesn't mean you can't take advantage of transducer technology and access reliable data to make your fishing more productive.

The Deeper Start is the perfect tool to help you get the most out of your fishing.

The Deeper Start is a sounder that can be used in basic display mode or in a more detailed mode for more accurate data.

This is a great way to introduce children to the natural world of fish and to teach them more about it.

For family outings

During fishing parties with friends or more sporty, casting/running, it locates the fish and gives you more time to fish without wasting time finding the best fishing spot.

 Deeper start in the water

Its particularity is that it only gives you the information you need without complex technical manipulation, often incomprehensible by the beginner.

It's a good idea to have a look at it.


The features


You simply need a rod with the Deeper on the end to know what’s going on under the water. Once in the water, it automatically deactivates and relays key information via your smartphone in a clear and user-friendly way. Deeper tells you instantly:

  • of what size (to target only large ones)

  • what is the total depth of the area

All with simple icons, displayed directly on the Deeper app, downloadable from Apple store and Google play.


Pocket Sounder

The size of an apple, it fits in your hand and is easy to handle due to its small size and light weight (65g).

Its small dimensions H 65 x W 60 mm, ergonomic shape, with a rounded base and a conical top make it easy to navigate.


Automatic commissioning

Once the app is loaded on your smartphone, attach your line with the supplied mounting clip and stopper.launch the Deeper and start fishing. Its orange colour makes it easy to spot from a distance.


Large scan area

The Deeper Start's single beam probes at a frequency of 120 kHz over a 40-degree angle. This provides the necessary accuracy. The result is a good compromise: repair of fish without bottom formation. 10 times per second, the area is scanned by the signal for a display that conforms to the real time reality.

It's easy to use.

Its range is 50 m distance and depth (i.e. 165 IP). Regardless of the depth of the area, it is effective because it detects fish from 0.5 m (1.6 ft)

The range is 50 m (165 ft).

Deeper Start with smartphone

Behaviour and ease of use

The display is correct and requires no interpretation or analysis, thanks to the simple icons, which is very convenient for beginners who don't have to worry about any settings.

No cellular data is required, the deeper features Wi-Fi Connection: powerful, large range up to 50m, which offers fast data transfer.

The Deeper Start automatically turns on when immersed in water, similarly it automatically turns off when removed.

The battery life is longer than that of the smartphone. To know if the battery is charged, the light should be on in fixed mode when the power cord is plugged in. If it flashes once, it is empty.

After approximately 2.5 hours of charging, with the help of its magnetic USB cable, connected to a phone charger or to a computer or car USB socket, it is ready for 6 hours of autonomy.


Do not leave your phone on the floor or in a pocket as you may lose the wifi signal. It would also work well with a tablet or laptop.

Conclusion and opinions 

The NOOTICA expert's opinion: "Easier to use, there is no depth gauge level. Without adjustment or analysis, 3 steps are enough: Pair the device, launch the app and see the fish!  Its record weight allows it to be used with a simple MH power rod, on a kayak, a float tube or even from the shore. If you want, you can know the weather, the phases of the moon, save your history and enjoy other features of the Fish Finder app."
