Topic: 999 Problem

[tomjohn]

Seems I lost my DI and SI on my Humminbird 999. The screens come up but they are enpty. NEED HELP

Check the "Transducer Select" menu under the Sonar tab to make sure "Hi Def SideScan" is selected ...(altho I would think even the SI and DI views would not show using a different selection)..

Also make sure the SI Range setting is set to a value that is more than the actual water depth ...

If that doesn't help; try cross-testing it with someone else's Humminbird Si model unit (any model will work for the test).

I had the same thing happen last weekend kind of.  I hate to admit this, but after a while I realized I had somehow hit my switch to go to my thru hull ducer!!  Therefore you don't happen to have a switch to change between transducers do you?
