It also shows that Makita are savvy enough to notice that a lot of cordless SDS drills are used underground on cave/mine projects, which may at least trigger a consideration toward useful design mods, and possible weight-trimming on future models. To be honest, most modern drills are pretty good in that respect anyway, but it's a good move, IMO, even though the target market is small - the promotional benefits, especially when seen dangling beneath a bolter in exciting expedition shots, could potentially be huge.
