We deal we both companies here.
We go way back with DS Dev.
As all have said it is top kit there for top price.
Bit like us
I went up and meet the guy's at Techstar/Starcom the other week.
They know their stuff.
They have put a lot of their kit into F1 boats and Honda FS.
Seems to do the job well and I understand is waterproof too.
Which ever way you go Dave both will interface with the M601.
