Hi All,

I have the above fish finder but I think I only have a 50khz transducer as when I change over the frequency to 200KHZ on the unit I get no pinging or display from the transducer.
I assume this is because it is on 50khz unless anyone knows any different.

If that is the case, where would be the best place to get a 200khz transducer and how much would they approximately cost and is it worth the extra money.

If it is possible already a dual frequency unit, how do i tell, and what could be wrong with the unit.

Any feedback on this would be greatly appreciated
