One of my primary mission when I bough the ROV was long drift dives in the Columbia River. I definitely agree with you about the boat. I’m a builder and an engineer by nature, so i’m always thinking of ways to improve things. That would be affordable, and would allow you to get out further and not be crouching under a sun-hood on the rocky shoreline. There are several Youtube videos where people have built their own pontoon boats from lumber and plastic 55gal drums. But as i’ve said before, you could really do with a boat. It’s also nice to descend at full speed and then slow down when I get about 15’ above the bottom. I think the usefulness decreases as the visibility goes past 50’ because it’s faster and easier to just pivot the ROV and look at everything around you.Īlthough, The Ping1D echsounder is always useful because it lets me know if I’m landing on something when going down a slope. The downsides are that it was useless on my Lake Chelan dives because the dive site is just a straight steep slope down to 250’ with great visibility, so there isn’t any reason to use an imaging sonar at that environment. Soda Lake, Washington “Zero Visibility Zero Problems” - Dive Log - Blue Robotics Community Forums I couldn’t see anything, but I was able to do some “IFR flying” by using the Ping1D to keep me 2-3’ above the bottom and the Ping360 told me my distance and angle relative to the shoreline so I knew where I was. It’s usually pretty easy to go parallel with the shore.Ī great example is when I went to Soda Lake. One of the very useful applications is that I can explore on the mud plane and see the bottom of the slope on the Ping360, so I know my distance from the slope and my angle to the slope. Most of the lakes around here have reasonably steep slopes to a mud plane. It’s extremely useful and I partly rely on it at most of my dive sites here where the visibility is usually 5-8 feet. I can’t tell you if it would be useful for you because that depends on your budget and the environment you dive in. I really like having it, and I also love the fact that it’s a fraction of the price of almost every other imaging sonar I have seen. So, what is your overall impression of the Ping360? Is it something i should consider buying? I’m going back to that spot anyways because I want to do a reconnaissance of the depths and temperatures before I scuba dive it this summer. That would probably be a great place to re-test it with different settings. I found a big rock wall at Lake Chelan the last time I was there. I haven’t uploaded the video yet.īlue Robotics basically makes no product demonstration videos outside of the initial product announcement videos, so I try to make some of these testing videos to help other people see how the products work in real life situations/environments and determine if it will work for them. I actually did play with the advanced settings at the end of my first dive this weekend. This ROV is my very first experience with sonar, so right now I only know the top level stuff of how it interacts with the environments. I tried to leave the testing videos as unedited as I can so the viewer can see my whole testing process and determine if my results are valid or not. I set the Ping Viewers settings about 1:00 in the video. I believe it’s 750 KHz and 32 microseconds. Out of interest, were you testing on high gain, or did you leave it on normal? It might be worth doing some testing to map out the maximum achievable distance across different water types and transmission frequencies - perhaps a project for the bluerobotics engineers, or an interested third party Out of interest, were you testing on high gain, or did you leave it on normal? It’s also worth noting that while the receiver is tuned to 750kHz, lower frequencies attenuate less so you may be able to get a little more distance by reducing the transmission frequency a bit (I’m not sure what drops off faster between the receiver sensitivity and the water transmittance). Theoretical maximum is 50m/165’, as per the technical details, but that depends on target size (a single ping would need to hit a 22x1.75m/73x5.75’ target to be fully reflected at that distance), and gets reduced by bubbles and other floaties in the water scattering and absorbing the sound, along with the composition of the water and the frequency of the sound. I did a … range test of the Ping360 … the max range was about 100-120’
