Why yes, the MKIV is available in SAE, Metric, Whitworth, as well
as a
sub-miniature version in the very popular RCH measurement standard.
All except the latter at no additonal charge.

With no demand whatsoever, the MKIV
should be available for ADS-B any day now.

All well and nice, but the big question *this winter is whether it
will be compatible with PowerFlarm.
