I have been really tired after work for the last 2 weeks, so I haven’t been too motivated to do a lot of video editing and I forgot to keep everyone updated on my adventures, so this is a dump of my last 2 weekends of shipwreck hunting.
I just placed an order for a DeepVision DE680D Side Scan towfish, so hopefully my underwater exploration capabilities will be exponentially increased in a few weeks. Right now I’m finding these shipwrecks just by scuba youtube videos, so it’s a very slow and unreliable process with very little information.
Edit: I forgot to mention that I now use the “Rainbow” custom gradient for the Ping360 made by @EliotBR. You can download it here: Ping Viewer - Custom Gradients - Blue Robotics Products / Ping Sonar Devices - Blue Robotics Community Forums
I recorded a quick demonstration video going through most/all of the gradients: Blue Robotics Ping360 Custom Color Gradients Testing/Demonstration - YouTube.
The GoPro had an SD card error so it’s not used. The ROV was accidentally in manual mode for the first part of the dive so that’s why it was so hard for me to control, and it took me a few minutes to figure out why it felt weird. I’m not sure about the the names of the wrecks and am basing my information on the video listed below.
3:19 Arrive at bottom
33:51 Tether almost snagged
35:37 Exploring back in the other direction to see if there’s any other wrecks
44:14 some frame object on the right side of the screen. I didn’t see when piloting
45:35 Water pump
47:25 Dock bumper strip
48:31 Avoiding the rope entanglement hazard
1:00:00 Section of steamboat? I didn’t explore it too closely since visibility wasn’t great and I didn’t want to get the tether snagged on it.
1:06:27 Playing with sonar while the excess tether gets spooled back in.
Found these wrecks from a dive video that someone made: Steamboat Graveyard, Lake Coeur d'Alene, ID - YouTube
Looking for the Georgie Oaks. There was a ton of deadheads floating around. There was one right under the boat when when I was pulling the anchor up.
5:55 Start to see what’s left of the Georgie Oaks
8:43 Group of bass
14:38 Looking at cable hull bracing
17:53 Steel plating
23:00 Exploring around to see what’s else is there
37:06 Big bass
Trying to find a wreck that was supposed to be here. We think it’s called the Cougar 2. I didn’t explore too much since the visibility was ‘bad’ and silt was getting stirred up very easy. I’m still paranoid about the tether or ROV getting snagged on something. This was the first time that the Ping360 could see a shipwreck before I could, probably because the other wrecks were sitting on a slope.
1:31 Big Fish
5:02 Bottom of cliff
8:59 First sonar contact from the wreck
11:00 Find the ship
17:22 Attempting to look in the hole
29:09 Surfacing to see the position and end the dive.
We knew about it from this video: Dive on Sunken boat Sandstar, Lake Coeur d'Alene ID - YouTube
We finally found it after 2 failed attempts. I think we were a little too far North East on our other attempts. I haven’t uploaded those videos since I was just driving around looking for a sonar return. I had the ping duration maxed on this attempt to put as much sonar energy into the water to get the best return, and it seemed to work since it picked it up around 120’ away.
0:00 Sonar contact bearing 246
1:57 Switching to Sector Scan
4:15 Visual confirmation
6:07 Lights off to test ambient light levels
8:37 Inspection sticker, looks like 1979
18:41 Name badge
28:04 Ending dive to check the real location of the wreck
28:33 external view of the ROV driving back to the boat
I put my tripod down to watch a group of little bass swim around. The ROV makes a few appearances in the first couple of minutes
There was supposed to be a shipwreck in the area, but I didn’t find it.
My boat location was roughly 47.664126, -116.771698
3:27 Group of fish
5:22 Tons of fish
9:24 Fish again
Seeing what was there. I kept getting confused on the ROV position so I surfaced a few times. It felt like I was going in circles.
0:47 Anchor on rock shelf near edge. It slid off and the boat started drifting.
2:51 North tip of Island
12:59 Big bass
17:02 Boiler that sits on the East side of the Island
Exploring somewhere around 47.613366, -116.684034 just to see what was there. I’m not sure what happened to the GoPro video files. I think I accidentally deleted them.
3:48 Concrete road barrier
5:49 Visible thermocline silt layer
9:37 Mud stirred up from catfish swimming away
12:42 Sonar contact (It’s a log)
13:15 Catfish running away again
14:19 Catfish sitting
19:40 Little Bass
25:00 Bass intercepts me
