GSD 20 software version 2.30

as of July 30, 2003

Changes made from version 2.20 to 2.30:

• Unit will now reacquire the bottom faster when moving quickly over large changes in bottom depth greater than 200 ft (60 m).
• Sped up re-acquisition by not alternating frequency unless the user has chosen dual-frequency mode.
• Updated company name and copyright information.

Changes made from version 2.10 to 2.20:

• Corrected a minor production-related problem.

Changes made from version 2.02 to 2.10:

• Added the ability to set factory defaults via the head unit. For example, a GPSMAP 2006/2010 can now reset the GSD 20's settings to factory defaults.
• Fixed potential problems with the serial communication related to memory leaks and baud rate changes.

Changes made from version 2.01 to 2.02:

• Fixed potential problems if disconnected from unit.
• Improved sonar noise rejector some. Now less likely to reject weak signals when rejection isn't necessary.

Changes made from version 2.00 to 2.01:

• Changes to support production board level tests.
• Fixed a bug that potentially caused problems loading new software to remote units.
