Looks like there has been no response to your question of a month ago & maybe you have already gotten your compass & no longer depend on your buddy to navigate.
I use two. One is a scubapro mounted on a slate that I keep in a BC pocket. That works pretty well for me & I use it more than the Suunto mounted on a console. Perhaps because I often pull out the slate to jot down notes during the dive & at the same time glance at the compass. However, both work equally well.
