Just what the title says, I'm looking for a digital temp gauge. Which is the best?

 

I use the new Defi-d Gauge and it is very accurate. very sensitive as well. if your cruising around at around 2 grand
and u bring the revs up to like 3-4 for like 5 10-seconds
it will raise the temp, and the defi gauge reports it instantly. so I think its perrrty accurate.

 

I have the one from summit that has a temp set point that can turn on a relay. It also records highest temp for that period run time.

 

So how good is the cyberdyne digital gauge?
