Default replacing the vacuum gauges with.....

Hello everyone. I want to get rid of my vacuum system and associated gauges and to replace them, a friend has a uAvionix all-in-one AV30 that does the job nicely for $2,500 new but was wondering if anyone else has found a better alternative (I'm willing to go a bit higher if for example, the display is bigger etc. Would the Garmin G3 do the same?

I went with a 10 inch sky view system.

The choices are endless. I have a simple Dynon d10 as the center piece of my simple panel as a replacement for the standard old school six pack. Has been completely reliable for 12 years of flying, fully electric with battery backup.

The options go up from there. I suggest that this kind of very simple and reliable instrument, coupled with a really good tablet based GPS nav/info program (foreflight, ifly gps or similar) provides almost the same capabilities as a high end fully integrated glass panel at a fraction of the price with a very low learning curve.

Pick something and enter the world of enhanced situational awareness and reliability.

For that kind of money you can get an entry level GRT Sport EFIS plus an engine monitor (4 cylinder egt/cht, oil temp/pressure, volts, amps, automatic alarms, etc.). Similar from other manufacturers.

This.... https://www.michiganavionics.com/xtreme-efis-ems/ and a... https://www.bestbuy.com/site/samsung...?skuId=6429419 along with... https://www.iflygps.com/ will cover all VFR flight needs for about $2000.00 including a full EMS with all probes.

The only thing I would duplicate would be the oil pressure gauge. A failed sender with pressure going to "0" will cause some unnecessary stress.

Default Garmin G5

Another alternative to the AV-30 is the Garmin G5. It will do the job of all the six pack gauges for around $1500 including a backup battery and it fits in a standard 3.125 hole.

Default AV-30

I put the AV-30 in my RV-6, with an OAT and GPS inputs.
It's an impressive instrument with a lot of features. It was less than $2500

my friend Marcel replaced the vacuum stuff on his -4 with 2 Garmin G5, with battery back-up. Works perfect, looks good, and you can just reuse the existing holes on your panel.

My ship also sports a dual G5 and a GNX375, fits all my requirements, and my wallet

Default living in a non-vacuum

Thanks for all the advice. I've decided on a G5 six pack since I already have a Garmin GDL-50 ADS-B using a Samsung tablet for a display on a RAM mount. As for a new/improved EMS, I chose a used Dynon. Your input was invaluable. Stop by Boulder airport if ever in need of a tied down and endless tools during your x-country trips.
Cheers

You will be very happy.
I have similar simple panel: G5, Dynon EMS and a dock mounted 796
I couldn’t be happier.
