I AGREE WITH KOMOS THAT ONIX HAS THE BEST DI AND THAT HB WITH A SLANTED DUCER WILL PRODUCER A GOOD PIC,I DID IT FOR A WHILE UNTIL I GOT THE 859 AND PUT IT ON CONSOLE WITH MY 998,DID NOT LIKE FLIPPING SWITCH BECAUSE I THEN WOULD NOT HAVE SI WHILE IT WAS ON WHEN I FLIP IT BACK TO SI, BUT SLANTED DUCER MATCH MY 859 OR MAYBE A LITTLE BETTER,THANKS RICKIE FOR THOSE NUMBERS,HAD FORGOTTEN THAT
