could a good flasher be used at the same time in deep water(40 to 120 ft.) with a lowrance lcx19c. ??

I should have said I know you cant use ducers of the same freq. A question might be what do flashers have for ducer freq. and is anybody using a sonar at one end of the boat and a flasher at the other.

You can use two sonar/flasher units simultaneously as long as they operate on different transducer frequencies. Units on the same same frequency will cause interference, usually displayed as vertical lines on the screen, because they are receiveing each others signal return.

I don't know about a flasher and graf together the flasher is hard to reed when there is interferance. When I'm icefishing with my lowrance 520 and someone has a Vexilar near the Vex interferance hard to reed and lowrace just gets a few vertical lines. The bigger, (more power one) will over run other one. Friend has a 520 and his kid has 67 and 520 works fine but 67 gets interferance when icefishing. I run 2 520s on boat and they work fine together.

To eliminate interference issues, transducer frequencies should be at least 50 khz apart. If the flasher frequency is 200 khz as well, you might look at a dual frequency transducer for the LCX-19 and run it in 50khz mode. That will eliminate any interference issues. The LCX-19 will be easier to read when interference is present than any flasher.
