I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

An Engine Monitor is only as good as its probes. That’s why Electronics International (EI) has taken the development of its probes, connectors, and accessories very seriously. EI has been designing and manufacturing probes for over 30 years. All of our probes have been designed in-house by our engineering team. Our team has studied, tested and designed temperature probes since the 1970′s. They have written research documents such as The Pilots Manual – Leaning and Diagnosing Engine Problems and Accurate CHT Measurements. Just as an Engine Monitor is only as good as its probes, a probe is only as good as its connector. That’s why EI’s engineering team developed EI’s proprietary OLC-2 connector. The OLC-2 connector greatly increases reliability and reduces installation errors as compared to traditional type connectors. Whether you’re looking for a reliable and accurate CHT, EGT, TIT or various other probe types, EI has what you need. With more than a half million probes sold and tested you can count on EI’s reliability.

The layout and quality is impressive.
Nice product and fulfills the requirement.
Sharp-looking gauges. [I chose EI because of your] reputation.
Excellent customer service. Without a doubt the best aviation part I have purchased.
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
. . . looks really good! Friends have these installed and give very good reviews.
Fantastic customer support!
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
