The MAQ Advantage
With no more blind areas to think about, the operator can focus on the tilt, range, and fishing area.
Universal Electronics Built for Longevity
Universal electronics, designed for all frequency transducers, are enclosed in rugged steel sealed cabinets to prevent corrosion and are cooled using heat pumps. Each unit has color coded plug-in components to facilitate easy installation and quick turn-around repairs when needed.
Each MAQ Sonar system includes:
Transducers designed to be rugged while at the same time sensitive enough to detect the hard-to-detect fish.
Captain’s chair joystick control.
Interface to popular navigation and net monitoring systems.
Free software updates via internet.

Difference Between Searchlight Sonar & Omni Sonar
The difference between Omni Sonar and Search Light (spotlight) or sector sonar can be explained through a quick example.
Searchlight and Sector Sonar
Searchlight sonar can only look in one direction at a time and must swing around to see what is in the other directions area by area.
To find fish, a set of elements move around a centre core and shows the fisherman the sea one slice at a time.
Since the vessel is not stationary, it is possible for a fisherman to sail by a school of fish without ever seeing it because the fish are out of sonar range by the time the “searchlight” moves to that side of the vessel.
Sector sonar is similar to the searchlight sonar while the slice which the sonar sees is larger, the system must still travel around to the 4 positions.
Omni Sonar
256 sonar elements on a cylindrical core sending out a continual signal in a full circle of 360 degrees constantly.
The cost difference between Omni, sector, and searchlight sonar is due in part to the number of elements and the complexity of the electronics and software.
The 5º Advantage
Bottom of Sand or Silt
In shallow water on sand or silt the MAQ, with its 5 ° beam, will outperform the competition in detection distance. It will see fish at a further distance close to the bottom. Remember 20 x depth for 5° beam and only 10 x depth for 10° beam.
MAQ 5° Vertical Beam Width = 20 meters detection for each meter of water depth
10° Vertical Beam Width = 10 meters detection for each meter of water depth.
In 30 meters of water MAQ sonar will achieve 600 meters detection distance.
MAQ 5° Vertical Beam Width = 20 meters detection for each meter of water depth
In 30 meters of water a 10° Vertical beam Width will achieve 300 meters detection.

Hard Bottom
In shallow water on rock bottoms the MAQ with its 5° beam will outperform the competition in detection distance. Remember 10 X depth for 5° beam and only 5 X depth for 10° beam.
In near surface fishing the 5° Omni Directional Vertical Beam Width means fish are detected closer to the surface before getting reflection back from the surface.
The result is improved detection distance. And finally in fishing near the bottom with the narrow beam we have better separation of the fish school from the bottom.
MAQ 5° Vertical Beam Width = 10 meters detection for each meter of water depth
10° Vertical Beam Width = 5 meters detection for each meter of water depth
In 30 meters of water MAQ Sonar will achieve 300 M detection distance
In 30 meters of water a 10° Vertical beam will achieve 150 M detection distance
Rotational Directional Transmit
The MAQ Sonar 22 KHz offers Rotational Directional Transmission (RDT), providing the largest verified detection distance of our products. Below is a comparison of RDT and standard Omni sonar features.
RDT
During transmission four 90° sectors of the transducer array (64 Elements) are phased to concentrate maximum acoustic energy into four directions (beams) in the horizontal direction.
By transmitting 8 discreet pulses at the beginning of each transmit/receive cycle each rotated 11.25° the RDT transmit cycle fully covers the area with the 6db increased transmitter pulse output and increases the detection distance in RDT mode.
Standard Omni
In a standard Omni system all elements (256) transmit a pulse at the same pulse phase to produce a transmit pulse in the all directions.
Phase adjustment is how an omni sonar can tilt the transmit and receive beams vertically in standard omni modes. From +10° to -45°.
