WESMAR award winning HD800 series sonar is designed for the two major fishing applications. The system features a split screen option for trawlers and a dual screen option for purse seiners, and offers both horizontal and vertical scanning. As an advanced tool for analysis of underwater conditions the HD800 is also used by some surface and bottom longliners.
Scan horizontally to locate fish schools and vertically to track them close to the bottom, under and to the sides of the boat, as the vessel moves forward. You can save all preset adjustments as the sonar switches back and forth between the two operations.
Advanced software in the dual screen mode allows for even further analysis of fishing conditions. It combines split screen and forward scanning screen capability while pulling up the overlay window. With this you can be scanning forward in search of fish and at the same time run a bottom profile. And as the soundbeam passes through the target you can activate a third screen. This vertical scanning (thickness mode) produces a window on the sonar that shows the density or size of the fish school you are monitoring, giving a side view of the target.
WESMAR has developed a new software mode for the HD800 sonar for easier detection of individual or dispersed fish such as a single tuna. This software will add a sparkle to targets that otherwise may go undetected.
