Generally about mounting All materials used for mounting and situated near the compass must be nonmagnetic or the function of the compass will be disturbed. You can check if something, e g a screw, is nonmagnetic by nearing it to the compass and also moving it sideways along the face of the cupola. If the reading of the compass doesn't change it is nonmagnetic. Compasses disturb each other if they are placed too close. The compass housing consists of two cupola which must be free to move with respect to each other, to compensate for temperature differences. Make sure you are not restricting this movement the way you mount the compass. Specific The 100P, 103P, 103PE compasses are intended for bulkhead mounting. With additions, see notes in table on price specifications and how to select page, they can become a quite nice free standing compasses.    The 1000 model  can be bulkhead mounted but also comes with a rear cover and therefore also makes a nice free standing compass.  They Ansar 2 and 4 compasses shall be mounted with the flange vertical.    All compasses has a screw, or a hole for a screw,  in each corner which can be used for mounting e.g. to a aluminum extrusion, with L-section, at the lower or upper edge.  The L-section can then be attached to e.g. the cabin roof permanently or in a way that it can be removed when not used.  Or it can be hung from the rear part of the cabin ceiling.  A piece of  L-section is available as an accessory, see price specifications and how to select. For, maybe less permanent use, the compass can be mounted on a piece of wooden plate which is strapped to the cabin roof. Put rubber strips under the plate as it musts not turn on its surface while in use, or you will get wrong indications. If the action around the compasses with movable makers may unintentionally move these markers you can mount a circular protective transparent strip a couple of centimeters, half inch, from the copula. For price see: price specifications and how to select.    Silva's has a mast bracket (see Silva's site) for Silva 100P, 103P, 103PE compasses. I guess, but don't know, that it can be used also for 1000 and 100B/H compasses with smaller modifications to the mounting holes in the compass bracket.
