Dolpinger K-12 Dolphin Pinger

The DOLPINGER K-12 is specifically designed for Voli nets and professional fishing applications. It does not have a built-in battery. It works by feeding from an external 12VDC battery.

DOLPINGER K-12 is a domestic acoustic deterrent technology that helps protect your nets and reduce your catch losses.

It is a professional acoustic deterrent system developed to reduce net damage and catch losses caused by dolphins and seals in fishing activities. Developed and produced in Turkey, this innovative technology is activated as soon as it is energized and starts to provide protection.

The device generates random acoustic signals that continuously vary between 5 kHz and 400 kHz. Thanks to the adaptive frequency algorithm, the possibility of marine mammals getting used to the sounds emitted is reduced and long-term effectiveness is targeted.

Key benefits

• There is no runtime limit as it is powered by a boat battery
• Developed and manufactured in Turkey
• Specially designed for marine conditions
• Maintenance-free compact structure
• Corrosion-resistant epoxy body
• Automatic operation when energized
• Reduce Your Costs: It prevents network repair costs and loss of labor. It extends the life of your network.
• Improve Catch Efficiency: Prevents fish in the net from being consumed or startled by dolphins, ensuring maximum earnings per trip.
• Respectful to the Marine Ecosystem: It does not cause any physical harm to marine mammals. It simply creates an acoustic barrier, keeping them at a safe distance.
• Save Time: It offers plug-and-forget convenience thanks to its smart sensors. It does not create extra workload during operation.
• 1-year one-to-one product replacement warranty against production-related malfunctions

Operation

The device starts to work when the battery is connected and energized. It emits high-power acoustic signals at random frequencies that vary continuously from 5 kHz to 400 kHz. Marine mammals (dolphins and seals) get used to fixed frequency sounds over time and can get close to the device. The DOLPINGER K-12's advanced adaptive frequency algorithm continuously mixes the sound sequence. In this way, it becomes impossible for living beings to adapt or become immune to sound, ensuring long-term and definitive protection. As soon as it is removed from the water, it automatically shuts off to save energy.

Dolphins and seals can cause serious damage to the nets and loss of prey while trying to reach the fish in the nets. DOLPINGER helps marine mammals stay away from nets, contributing to reducing net damage and maintaining more efficient fishing activities.

The effective distance of the device; The salinity of the water can vary depending on environmental factors such as temperature, clarity, current condition and ambient noise.

In the field observations, the average impact distance

• An area of approximately 600 meters in diameter in the Aegean Sea and the Mediterranean
• An area with a diameter of approximately 250 meters in the Sea of Marmara
• An area of approximately 400 meters in diameter in the Black Sea

measured as.

Uses

Thanks to its compact structure and high compressive strength, the DOLPINGER K-12 can be used safely in all areas of maritime.

• Purse seine and Voli Nets: Used when collecting nets or hunting.
• Aquaculture (Fish Farms): It is hung around the cages at strategic angles to prevent predator attacks from outside.

• After purchasing the product, you should add cables according to your needs. The cable must be water resistant with a cross-section of 2x1.5mm.
  You must definitely cover the cable splice with a durable material such as epoxy.
  In case of damage caused by the joint, the product is not covered by the warranty.
• It is designed to operate at sea. Work on land for no more than 1-2 minutes. Otherwise, it may malfunction.
