Fish Finder And Transducer

OVA Professional Fish Finder with 12-Inch Sunlight-Readable Vertical Display – 1500-3000W Output for Commercial Fishing Boats

For professional fishing boat captains who need to process sonar data at a glance, this OVA fish finder features a 12-inch vertical display readable in direct sunlight. The upright screen orientation shows more water column history than square displays, helping you spot fish school movement patterns. With 1500-3000W output power and flexible frequency support 50&200kHz), this system performs in both shallow and deep waters.

Designed for Professional Fishing Operations

12-inch vertical sunlight-readable display – The upright format displays more historical sonar data vertically, allowing you to see how fish schools moved through the water column over time. Sunlight-readable construction ensures visibility on open fishing bridges.

1000W output power – High transmit power penetrates deep water and maintains bottom lock in rough sea conditions. Suitable for offshore commercial fishing operations.

Dual-frequency display – View 50kHz and 200kHz returns simultaneously on the split screen. Identify fish schools more efficiently by comparing wide search beams with narrow detailed beams.

Multi-function knobs and dedicated buttons – Operate important functions without navigating menus. Tactile controls work with wet or gloved hands on a moving fishing boat.

Frequency Flexibility

Flexibly support 45-200KHz frequency range for use in different shallow and deep waters. Select the optimal frequency for your current fishing ground:

Low frequencies – Wide beam width for shallow water search and large school detection

High frequencies – Narrow beam for deep water bottom detail and individual fish arch separation

Technical Specifications

Display and Expansion Modes

Auto Expansion – Automatically adjusts display scale to keep bottom in view as depth changes. No manual range adjustments during normal operation.

Manual Zoom – Select any depth range to magnify. Examine bottom structure or mid-water fish schools in detail.

Bottom Lock – Locks the display to follow the bottom contour. Shows fish and structure immediately above the seafloor – critical for bottom fishing species.

Data Integration

Input data (IEC61162-1 NMEA0183 RMC) – Receives GPS position and speed data from your chart plotter for accurate sonar processing relative to vessel movement.

Output data (IEC61162-1 NMEA0183 DPT, DBT, GLL, MTW) – Feeds depth, water temperature, and position data to autopilots, radar systems, and network displays.

Serial port for printing (DPU-414 compatible) – Print sonar screenshots and bottom profiles for fishing logs or captain's reports.

Alarms for Professional Operations

Depth alarm – Set minimum and maximum depth limits. Alarm sounds when vessel enters unsafe shallow water or leaves productive depth range.

Voltage alarm – Monitors vessel electrical system. Warns of low voltage before fish finder performance degrades.

Temperature alarm – Alert when water temperature enters target species range (tuna, salmon, etc.).

Included Transducer

This professional package includes a matching transducer optimized for the 1000W output power. Contact our sales team to confirm transducer type (hull mounting style, beam width options) for your specific vessel and fishing depths.
