Splashproof, Rugged Casing.
The 320M Jr is a splashproof version of the proven 320M Marine echosounder. The rugged, compact casing of this single frequency sounder provides splashproof operation and waterproof transit that makes it ideal for open boat survey.

High Resolution, 32 Grayscale Printer.
Using the built-in thermal printer, the 320M Jr produces a high resolution record accurately showing sediment layers and bottom profiling. Data is be printed on plastic film using the 32 step Grayscale printer with 1600 pixels per line.

LCD Menu Display.
The KEL 320M Jr has an LCD display with simple 2-button control that provides access to parameters such as sound velocity, draft, TX blanking, serial port assignment, time and date setting, and others, as well as a variety of self-test, communication and configuration features. All settings are retained in non-volatile memory and recalled on power-up.

Connectability.
Three RS232 serial ports support communication with personal computers (and laptops), GPS receivers, NMEA input and output devices, sound velocity sensors, heave sensors, remote depth displays and survey data loggers.

Standard Features

Digital Signal Processing (DSP).
The 320 echosounders do all signal processing digitally. There are many advantages to an all-digital system, including the inherently higher performance and greater stability of digital filters. The processing is performed in software which can be programmed to accommodate any frequency, bandwidth, or pulse length, eliminating the need for multiple analogue hardware filters.

Field Programmable Software Upgrades.
KEL 320 Series Echosounders are unique in their use of in-circuit programmable flash program memory for storage of all firmware including signal processing algorithms and communications drivers. Echosounder firmware can be field upgraded with the latest revision provided via the internet or on a disk from KEL. This firmware can be downloaded into the echosounder using the survey computer. Users can thus benefit from the improvements and additions to the software which are continually being developed.

Easy Transducer Interface.
The Knudsen 320 Series Echosounders can be easily interfaced to most existing transducers, saving the expense of new transducers and dry dock installation.
