I've had both and prefer the EDM 700 for the download capability and extra
features such as voltage monitoring. Yes, you can monitor your gauge but
with the EDM alarms set at your less than ideal voltage, why add another
instrument to your scan when one will do.

Also, I do not believe you can get integral fuel flow w/ JPI.

The sales info about the probes seems like hype. But I have had good tech
support from both companies.

FWIW, {|;-)
