Well, look, I mean, this year we set out to do something like $2 million of DAVD revenues. And I think that we have met that actually, and we've exceeded that a little bit. What I see, as you've rightly said, the tethered version is now fielded. This is now an item that's open for purchase by any command in the U.S. So that's very good news for the business. In addition to that, what we're seeing is that, as I mentioned, is that we've got one European -- major European offshore service provider having conducted rigorous trials, have confirmed that this could be game-changing for their organization and their intention to adopt the DAVD. We also have pre-adoption discussions in Japan. And later this month, we will be running training with a major Japanese customer that we think will adopt the DAVD in this calendar year. So, I think we have a swirl of -- or swell of good activities around the DAVD and we do expect that, that will be a significant part of our revenues in 2024. On the untethered version, I would expect that to be more the backend of 2024, because, as I pointed out earlier, I think that program has moved forward. I'm very, very excited about that because for the first time, Brian, we have a foreign Navy jointly funding the program and having their own requirements in the U.S. work package. And we've always said that one of the paths to adoption will be the U.S. Navy itself working with foreign navies on adoption, and we're seeing that coming through. So, I am really, really excited about the progress. I mean, in this quarter, we were funded to the tune of $750,000 of $1.8 million contract, and part of that is for eight evaluation systems, and the other part is for some customization work for the Navy. So, I'm really excited about the DAVD, the prospects for the business for the DAVD. And I think we're making really, really good progress because a number of things happened in this quarter. As I said, we've got a European -- a major European offshore service provider being happy about the trials. We also are doing pre-trial training in Japan. Also at the same time, demonstrating the capability to a wide breadth of Japanese customers. So, I feel really, really excited about where we are with the DAVD. And I do believe that the biggest opportunity we have with the DAVD, as I've always said, is going to be the untethered version. And therefore, what we are seeing now with that variant is that it's moving into its second evaluation phase, which is that they've bought evaluation systems and we're doing some customization work for them.
