I think Blair will talk a little bit more about that. But just to say that, let's see, DAVD tethered system is, as you know, operational. So, I think if last year, in terms of DAVD, we did around $1.5 million in revenues. This year, we're targeting $4.5 million in revenues for DAVD, so a huge jump in DAVD revenues. So, I would expect and what I'm excited about on the DAVD revenue side on the tethered systems, that we have that are operational, we're seeing new commands putting in for acquisition budgets, and therefore, the product is moving forward. The biggest barrier to, adoption at scale is really when the technology falls into disuse. But what we're really seeing is an expanding footprint for the tethered system. And as I said, last year, we did $1.5 million in DAVD sales. This year, we're targeting and feel pretty good about $4 million to $4.5 million for DAVD sales. And a large part of that will be made up of the tethered system, for example. And just to talk a little bit more about that also, Brian, what I'm excited about is, we're seeing consistently pull-through sales for the Echoscope, so when we get a requisition for DAVD, we're seeing automatically a bundle of Echoscope sales. So that's the sort of programs we've been targeting, and I feel we're seeing that now maturing. So, for this year then, as I said, we expect to see for the DAVD system, for the tethered variant, we expect to see new orders, for new commands. For the untethered system where we've just received $800,000 for 16 systems, that's a pre-adoption that is really crucial for the full-scale adoption. So, I think, really, these systems will be fielded, and it will be performance-related. But I feel we've reached an critical milestones within that program. As Blair mentioned, delivering, the new generation of head-up display, which has 200% more resolution and a smaller form factor, which means for us, it opens the technology significantly. And on the back of that excitement with the user community, we've seen the first orders for these 16 systems free adoption. And I think in terms of Blair, can you talk a little bit about the road map for broader adoption following the delivery of the 16 systems?
