The supplied mounting bracket holds the SM-3 secure in the roughest of conditions but it is still readily accessible when needed in an emergency Additionally. while the SM-3 and its bracket are significantly smaller than the SM-2 counterparts. the SM-3 bracket conveniently maintains the same mounting hole pattern as the SM-2. allowing for easy retrofit with no additional adapter plate required
