Description
24-month warranty.
Important note: The boats are fitted with a gyroscopic sensor, which helps maintain course and stability in the water. For this reason, they do not function correctly on land. If you attempt to test them out of the water, the motors may appear to rotate unevenly, stop or fail to respond to commands.
This is not a fault – it is how they are designed to work. On the water, the gyroscope receives the necessary feedback and the boat handles perfectly, ensuring a stable and controlled ride.
Fishing boats are designed exclusively for use in calm waters, such as lakes, marshes or other areas without strong currents.
Their use at sea is not recommended. Waves and wind can affect the boat’s stability, posing a risk of sinking and loss of connection with the remote control, which could result in its loss. Contact with salt water may damage their internal components and invalidate the warranty.

MAXIMISE YOUR FISHING SUCCESS
The iUni V803 PRO boat is the ideal tool for both amateur and professional anglers who want to place their bait and rigs with precision, speed and efficiency over long distances or in places are difficult to access from the shore.
The boat is equipped with a high-performance sonar, designed to provide you with a clear picture of the seabed and the presence of fish in the fishing area. The moment the sonar detects a fish, the remote control will emit an audible signal (a beep) to alert you immediately.
The built-in GPS positioning system offers a significant advantage in terms of accuracy and efficiency. It allows you to save up to 200 fishing spots, intelligently organised into 4 different zones. In this way, the boat remembers your favourite spots and navigates to them automatically at the touch of a button, after which it waits for your command to release the bait.
Equipped with a powerful 5200 mAh battery, it provides around 2 hours of operation. With a maximum range of 500 metres, this boat provides access to remote fishing spots.
BUILT-IN FISH FINDER
With this sonar, you’ll significantly increase your chances of catching fish by locating the areas with the highest fish activity.
The maximum scanning depth reaches 100 metres, with a scanning angle of 90 degrees.
On the screen, you’ll be able to see the location of the fish, their size, the depth at which they’re swimming, the water temperature, the battery level, as well as the shape of the seabed and underwater vegetation.
It allows you to configure the fish alarm mode according to your preferences and fishing conditions. The moment the sonar detects the presence of fish beneath the boat, the remote control will emit an audible signal (beep) to alert you immediately, thus ensuring you don’t miss a single catch.


PRECISE POSITIONING WITH GPS + BEIDOU
The V803 PRO model utilises two global satellite networks simultaneously: GPS and Beidou.
By combining the two networks, the boat connects to a much larger number of satellites. This reduces the positioning error to a few centimetres, even in areas with vegetation that could block the signal from a single system. If a GPS satellite loses its signal, the Beidou system automatically takes over, ensuring uninterrupted and reliable navigation.
Four fishing zones can be configured, and 50 waypoints (positioning points) can be set for each fishing zone, making a total of 200 fishing waypoints. The waypoints across different fishing zones do not interfere with one another. This feature is extremely useful for anglers who wish to return to spots where they have had success before, or to explore new areas with potential for a catch.
Once saved, you can send the boat to any of the 200 points at the touch of a button. The boat will sail autonomously, reach its destination and wait for the command to release the bait.
REMOTE CONTROL WITH ILLUMINATED BUTTONS
The boat is equipped with an advanced 2.4 GHz remote control, which ensures stable, interference-free communication.
The colour HD screen displays the boat’s direction, the GPS signal, the battery level (for both the boat and the remote control), the fishing area, waypoints, light controls and the bait-release system, where the icon for each tank flashes on the screen to provide immediate visual confirmation as soon as the bait has been released.
For night-time use, it features illuminated buttons that can be activated by briefly pressing the power button.
The remote control has a built-in 3.7V 2000mAh battery, which is recharged via a modern Type-C port.


RECHARGEABLE BATTERY – 5200MAH
With a 5200 mAh rechargeable battery (included in the set), the boat has a running time of approximately 2 hours (running time is affected by the weight of the lure and weather conditions).
The compartment allows two 5200 mAh or 12000 mAh batteries (not included) to be connected simultaneously, thereby doubling the operating time. It ensures a longer and more effective fishing experience.
500 M SAFETY ZONE
This feature acts as a virtual safety perimeter between you and the casting boat.
The GPS system constantly monitors the distance between the shore (the starting point) and the boat. If you attempt to move the boat beyond a radius of 500 metres, the system will detect that it has left the perimeter. In this way, this function ensures that the boat will never leave your area of control, thereby avoiding situations where the boat becomes stranded on the open sea without a signal.
The moment the boat reaches the maximum safety limit, it will automatically activate the Auto-Return function.


ONE-CLICK RETURN
No matter where it is in the water, the boat automatically returns to its starting point at the touch of a button (you must set the starting position in advance for this function to work). Furthermore, the boat is equipped with a smart safety system and will return to the starting point on its own in three critical situations:
- Low battery: when the battery level falls below a safe level.
- Lost signal: if the connection with the remote control is lost.
- Out of range: if the boat exceeds the maximum control distance.
BUILT-IN GYROSCOPE
The iUni V803 PRO boat has a built-in gyroscope that automatically corrects course deviations caused by wind, waves or uneven bait distribution.
This ensures the boat maintains a straight course, even in challenging conditions.


4 INDEPENDENTLY CONTROLLED TANKS – MAX. CAPACITY 3 KG
The four tanks have a combined capacity of 3 kg and can be controlled individually using the dedicated buttons on the remote control.
Press the tank button briefly to activate selection mode; by default, the front-right tank is selected first. The selected hopper lights up blue; to release the bait, press the OK button. During the release, the box lights up red, returning to white once the command is complete. The selection order follows the numerical sequence shown in the diagram.
The large 3 kg capacity allows you to carry a significant amount of bait, so you don’t have to reload too often.
This is a bait boat specifically designed to facilitate the process of placing and releasing bait in a precise and efficient manner.
AUTOMATIC CONSTANT-SPEED
CRUISING
A revolutionary feature of this boat is the autopilot function.
You can activate the navigation system, which keeps the boat travelling at a constant speed and in a straight line.


TWO POWERFUL ENGINES
Thanks to the two powerful 390 engines, the boat can reach speeds of up to 15 km/h.
The water-cooling system ensures effective cooling of the engines when operating at high speed, guaranteeing their longevity.
Each propeller is surrounded by a large guard to protect against various debris or objects in the water that could obstruct the propellers.
2 SPEED SETTINGS
The boat is equipped with a flexible propulsion system that allows you to adapt the speed to suit your needs:
- Low speed: ideal for precise manoeuvres close to the fishing spot.
- High speed: can reach up to 250 m/min, making it ideal for quickly reaching fishing spots located at long distances (up to 500 m), or for easier manoeuvring when it is windy and the water is choppy.


CONTROL RANGE – MAXIMUM 500 METRES
By using two aerials, the boat ensures a more stable signal transmission and strong resistance to interference. This helps to maintain a clear connection between the remote control and the boat.
It can be controlled from a distance of up to 500 metres, allowing you to explore larger bodies of water without losing control.
SMART LIGHTING
To enhance the night-time fishing experience, the boat is fitted with two front headlights and two red/blue signal lights at the rear.
The smart rear indicators give you full control even at long distances or at night:
- Direction indicators: when you turn, the boat alerts you visually – the left-hand brake light flashes red when turning left, and the right-hand one when turning right. You know exactly which way the boat is heading at a glance!
- Low battery warning: both rear brake lights flash red to warn you that the battery level is critically low. This is a clear signal that you need to bring the boat ashore to recharge it.
- No-signal indicator: if the boat is not connected to the remote control or the signal has been lost, the tail lights flash alternately in red and blue.
The lights can operate in either flashing or steady mode.


BATTERY LEVEL DISPLAY
It features a digital battery level display, so you are always informed of the remaining capacity.
When the boat’s battery is nearly flat, you are warned in three ways:
- Boat indicator: only one red line remains on the boat’s display.
- Visual signal: the rear indicators flash red.
- Audible alarm: the remote control emits a continuous audible signal (alternating long and short beeps).
RIG ATTACHMENT FUNCTION
The two bait reservoirs at the rear allow you to secure the rig by releasing it together with the bait.
This is also useful for preventing the fishing line from becoming tangled.
