New! Bellman's "Sonar Visual Aid Kit"

[Bill Nichols]

'Bellman' has sent me his Sonar Visual Aid Kit. It's posted now at my site in the 'Downloads' section. It's designed for Dangerous Waters, but should be equally useful for Sub Command (except for the sample mission, which is for DW only, of course).

Description :- Instructions and photos for making a simple and
effective pinboard to assist in learning manual sonar.
A practise Scenario and run through of the system.
A Progress Chart for logging contacts and frequencies, classifying,
and filtering targets.

Thanks, Bellman!
