seems like things are a little different now that i've got the new update. i didnt have time today to make many adjustments but so far i not sure if i like the clarity that im getting with the new update. all the pictures are using the 455khz.i didnt have time to try the 800. some are with the si transducer and some are with the 360 pod.so far im having better luck with the si transducer.
