Thanks Ed.

Have to be over the fish!!! Sorry couldn't resist. I have the HB180 which is similar. Try higher sensitivity settings. Also check to see if fish ID is turned on. Never had success using raw data.

Then test by finding the fish.

Yep Fish under the sending unit can prevent clear screens! ( my screen has been clear way to long!)

Best way I know how to set the sensitivity is to drop a jig down underneath the transducer and then turn Your sensitivity up until You can see Your jig moving up and down as You give it motion. Then dial back the sensitivity until it is gone. Then bring it back and stop. You are looking for that sweet spot that is good enough to show your jig but keep the clutter off. If Your finder can see Your jig, it can see fish.

I'm sure You know this already but sitting still, the fish will show up as lines on Your screen as will your jig. When you are moving, they will show up as arches. Hope this helps.CF

I caught some fish but could not see them on the monitor. I will play with the sensitivity and do the jig trick as suggested by crappiefarmer.
Thanks guys, I will let you know how it turns out soon.
