New in Echoview 4.10 for all users
Welcome to Echoview 4.10!
We are pleased to announce the release of Echoview version 4.10. In this release, we continue our development of Echoview by improving the automation of tasks in our scripting module and with Echoview virtual variables; providing new visualization tools such as the on screen Integration line and a Threshold response graph, and supporting new instruments.
New features are presented in two categories:
New features for all users
New features for users of specific echosounders
New features for all users

Benefit |
Virtual variable enhancements |
The following enhancements extend the usefulness of virtual variables when doing complex analyses of your data.
|
User interface enhancements |
These enhancements give you better control over Echoview's workspace. They make your work easier by giving you easily accessible information about your data.
|
New Threshold Response graph |
The Threshold Response graph is a tool that can help you probe the composition of regions or selections in Sv echograms. The graph plots Sv threshold values against NASC for a selection. One of the potential uses of this graph is when a school is composed of two different species. A graph of the school region will show a visual jump in NASC as the Sv threshold changes. A value can be chosen from the graph to use as minimum threshold in order to allow school detection of only one of the two species. |
New scripting commands |
These new settings enhance the scripting module (deprecated scripting model for Echoview 5.0) and makes scripting with Echoview more powerful.
|
New scripting automation model | We are pleased to introduce support for scripting using COM object automation. The key advantage of this automation model is that Echoview can pass information back to the script. It is now possible for scripts to make informed decisions, request decisions from the user, and pass information from Echoview to the user. If you are interested to know more about COM automation, please contact us for further information. It is important to note that COM automation is in a highly developmental state and that we cannot guarantee backwards compatibility in future versions. |
Support for new file formats and file format enhancements |
This release introduces support for a number of new file formats. Echoview becomes more versatile by handling data from an even wider range of echosounders.
|
Data generator operator enhancement |
New algorithms and settings for the Data generator operator now offer the options of creating a TVG curve with or without a user defined TVG_override value and/or sample offset value. This may benefit the noise analysis of and noise mitigation strategies for your data. In addition, references on the topic of Background noise removal have been added to the Echoview help file. |
Resample operator enhancement |
A new setting to use the start and stop ranges from operand 1 for the Resampled virtual variable. This offers a simple way to match ping geometries. |
Fish length operator examples of species specific constants |
A table of species specific constants and references are tabled on the Fish length algorithm page. This information may provide some guidance in the use and applicability of the fish length operator to your data. |
Integration algorithm enhancement |
Expanded the availability of the integration algorithm for Multibeam cruise scanning. The H-mode beam type is now supported. |
Enhancement to TS variable calibration settings. |
Single target detection operators use the Transmitted pulse length in their calculations to produce a virtual variable containing detected single targets. Echoview now supports this setting on the Calibration page of the Variable properties dialog box for all TS variables. File formats with this new support are:
