CH-250 Color LCD Searchlight Sonar

The CH-250 is a revolutionary new, high-performance searchlight sonar designed for a wide range of commercial fishing vessels. Fish and underwater objects are displayed on a compact active matrix color LCD screen. Target echoes are presented in 8 or 16 colors depending on the received echo strengths. The highest echo level is painted in red and next strongest echo in orange, and other colors follow with reducing echo levels. One of the echo strengths can be displayed in white to enhance that specific echo level. The background color may be customized for optimum viewing at day or night. An operating frequency can be selected from 60, 88 or 150 kHz.

The CH-250 is provided with eight operational modes including Sector or Full circle scan, Vertical scan, Combination display of Full circle and Vertical scan, Historical or VideoPlotter. The combination of Full-circle and Vertical scan mode helps evaluate the distribution of fish school in horizontal and vertical planes simultaneously.

The CH-250 provides three modes to track a targeted echo: manual mode, target lock mode and L/L mode. The target lock mode permits automatic tracking of a target fish school within a predetermined search zone after it has been acquired in manual operation. In the L/L mode, the beam is locked to the position (such as a fish shelter or reef) specified by the target marker. This mode can be enhanced with DGPS position input.

The compact display design allows a flexible and space-saving installation at your navigation station. With an optional interface unit, a conventional CRT or LCD monitor can be connected as a substitute, backup or remote display of the standard display unit. The low-profile hull unit requires only a limited space for installation. There is a choice of hull units, either 250 mm or 400 mm travel.
