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.
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.
