Cyberdyne Gauges??

[Frederick Smith]

Has anyone tried the Cyberdyne Digital Gauges? I have a 250 deg. VDO
water temp gauge that really is useless if you are trying to
read the temp between 180f and 220f. Some thing that reads more 
accurately center scale would be nice. 

When the gauge reads 190f an infrared temp "gun" reads 206f.
The rad fan comes on as per spec. if I use the infrared
device on the fan switch. Cut in and out is within a degree or
two of the temp spec on the switch. I have tried different
VDO senders to no avail.
