Dive Computer on Light Arm

Thought I would also chime in to this old zombie thread, especially since someone asked about one transmitter and two computers.  I run a single transmitter feeding info to a Shearwater Teric on my wrist and a Hollis DG 03(?) on a float arm.  The Hollis has the original buckle-type strap, and in order to allow it to cinch down enough to stay in place I have it over a section of inner tube.  Also, never noticed any interference from the strobes firing.
