Super clock is everything EI claims. I canât wait to install it and fly with it. Be sure to purchase the LED controller (enables dimming the bright LEDâs).

After the installation was complete, it works as advertised. The only issue we had during the installation was that the glare shield interfered with mounting due to the depth of the clock. If you are planning on using this as a replacement, make sure your old clock has the same depth measurements or that the glare shield wont interfere with the mounting process.

Installed this to replace the OEM clock in a Cessna 150. Works great and easy to see.

The clock has all of the features I need. I do think it is overpriced considering I can get an apple watch for less. And it is larger than I expected. Again, my apple watch can detect afib and is a 20th the size!

This is the second SC-5 clock I have used in my aircraft (Archer II of 20+ years). The first lasted well over 10 years, but began behaving oddly. I suspect the battery was giving out, and it cannot be replaced by the user. If this one lasts as long it will make it to the end of my flying career. As another reviewer mentioned there is no time change except by switching master off and on. A couple of minor changes could have made this a five star clock.

Q: Does the SC-5 use 0.3 amp when aircraft is not operated or is it only when aircraft is in use?

The SC-5 has a built in battery and does not draw any power while the aircraft master is off. Once the avionics bus is turned on it will draw 0.3 amps to run.

Q: Does the EI SC-5 clock display the time even with the master switch turned off?

It will keep time when the master switch is off but will not show time when the master switch is off so not to drain the aircraft battery.

Q: Will the EI SC-5 Super Clock show time in HR and Tenths when engine is off? Like a Hobbs?

No. The engine time will only display when power is supplied to the instrument.

This clock has to be sent back to EI for the battery swap. Please call EI to get an RMA number prior to sending it in.
