11/15/2015 9:27:00 PMyeah, a second thanks for the sonar. Help me out, what are the balls on the screen? How do you know? And why the split screen? My old hummingbird just shows fish images, which are generally bogus. If I were to see a ball like that, it would tell me it was suddenly 20 ft deep. Im sure I need some better electronics, but dont quite know why yet...

11/16/2015 6:36:00 AMThe masses on the screen are most likely stickelback. This is more of an educated guess than anything else. Whatever is making up the balls is not composed of things larger than a few inches in length or you'd see more individual arches in the masses. In lake Washington, stickleback, smelt and mysis shrimp are the main sources of these large groups of bait. During the daylight hours, the smelt and mysis shrimp are typically down much deeper, 100' or more, so eliminating those leaves the stickleback. I ran the split screen to show what the differences in frequency and cone angles has on your view under the boat. I'm trying to put together a presentation on fishing sonar and I needed to collect some more images.
I'm almost certain your sonar unit's fish ID mode can be turned off, just need to find it in the settings. I really don't know why manufacturers still offer it as an operational mode when all it does is provide false information.

11/16/2015 7:38:00 AMG-man, when you get around to your sonar presentation, I hope that you will announce it on here. Maybe it is via a Puget Sound Angler's meeting? or whatever the group is that you have presented with before?-- is it too early to request good schooling on SI ? (-:
Also, when looking at the image that you have in 150' of water, is that a thermocline at about 65'? I know you said 90-100', but I don't see anything in that image at 90-100'.
Thanks.

11/16/2015 11:49:00 AMQuad, I'd most likely present it at one of the PSA meetings. I'll give a heads up once I have a date set. I don't have a side imaging unit but did get the opportunity to use one about a month ago. Concepts are all the same but you are given a few more details to determine what is going on under your boat.
The image is showing what I believe is the top and bottom of the thermocline in that section of the lake. I was in about 117' of water and I suspect the thermocline was moved a bit by the Cedar pumping in a bunch of cold water. The lake is in the process of turning over so you'll see some strange things on the sonar. With another big storm on its way, I think the turnover will be complete by week's end.

11/17/2015 1:57:00 PMThanks for the thoughtful response! Yes I can turn off fish id mode on my old dx200, but I know less about what im looking at than the hummingbird does. Terms like side imaging and different frequencies dont mean much to me either, Im still along way off from buying a new unit, but need all the info I can get before trying to decide which one.
I went for the wireless bow mount and downriggers this year, maybe next year on the sonar. I think by then, my accessories will be worth 2-3 times more than the boat!
I would be very intrested in a sonar presentation.
I got to witness a very dramatic turn over this year on Lake Curlew, Didnt know what the term meant before that.

11/19/2015 12:03:00 PMIm just about done getting my boat re-rigged and set for fishing again. Lake Washington Cutthroat will be my first stop. Hows the fishery from say now until the first couple months of the year?

Chrome_chasin - It is tough this time of year and get's tougher through the winter months. At times it can be on fire with the sea-run fish migrating in to spawn, but once the fish head up into the rivers and streams, it slows down to a crawl.
