My Sumlog didn't work and a new transucer is £187... So, pulled it out and took it to bits and the reed switch was busted. One new reed switch from Maplins for the aforementioned £1.57 and some fiddly soldering plus a bit of silicone sealer - and one fully working log! Oh the magnets were a bit weak so another £1 or so bought 2 new ones! Took the Fairey out and thrashed an indicated 26kts out of it. Brill! 
Anyone who needs advice on "how to" on this let me know.
