Dedicated DI unit beam coverage

DI sonar coverage:
45 degrees at 800kHz, area covered = 0.83 X water depth
75 degrees at 455kHz, area covered = 1.53 X water depth
________________________________________________

DI from SI beam coverage (approx.)

Narrow around 20 Degrees or 1/3 Depth,
Medium around 60 Degrees or equal to depth,
Wide is approximately 90 Degrees or 1.5 times the depth.

Navionics year date codes...

East list as an example...:

E is a 2005
E2 is a 2006
E3 is a 2007
E4 is a 2008
E5 is a 2009
E6 is a 2010

E-6 is also on the newer cards since there are no more annual issues. Newer cards are updateable and can be yesterday or today's data

From Greg on another forum:

i]The unit has two tests that it runs to determine if a transducer is connected or not. The first is to check for the presence of the built-in temperature sensor. If one is there the unit should automatically go into the Normal operation mode. If it does not detect the built-in temperature sensor it “pings” the transducer and listens for a ringback. If it detects any it assumes a transducer is connected and automatically goes into the Normal operation mode. If it doesn’t detect any ringback it assumes no transducer is connected and automatically enters into the Point Of Sale Simulation mode. The ringback detection is not a 100% test though, so you could have a good transducer connected to the unit which it cannot detect. This is why the Demonstration menu was added. Set it to “Off” and the unit will go into the Normal operation mode regardless of whether it detects a transducer or not.[/i]
