Twelve years ago, before SkyVoice became an industry leader in height announcers, it was a "non-legal" experiment in my own Piper Cherokee.
As a student pilot, I struggled to correlate the sight picture with actual height during landings. I needed a co-pilot to tell me exactly where the ground was—so I built one. I developed the first SkyVoice prototype to help me pass my Private Pilot checkride. It worked.
Through that process, I realized every airplane is different. A "one-size-fits-all" radar doesn't work. That’s why SkyVoice features Triple Isolation—a level of precision and customization that the Garmin® GHA™ 15 simply doesn't offer.
My experiments in that Cherokee taught me one thing: focus is better than flood.
This is the SkyVoice Secret: You can program the device to ignore any reflections within a specific "Blind Zone" (e.g., the first 1–5 feet). Even if your sensor is mounted near a step, float strut, or gear leg, the device "blanks out" the interference and only listens to the runway.
With over 4 years in the certified market, our algorithms are tuned by hundreds of pilots. We solved the "false return" issues years ago - issues that new entries into the market are just now discovering.
Because I built this to help me learn, I added the reminders a pilot actually needs. Unlike the GHA™ 15, SkyVoice provides:
I didn't build this to be a "product"; I built it to be a solution. I spent two years flying my Cherokee with "non-legal" prototypes until I knew the math was perfect. I discovered that a Blind Zone was the only way to ensure 100% reliability across different aircraft types.
Garmin® wants you to buy their $850 wiring kit, their $500 leveling kit, and their $4,000 glass display. I want you to have a safer landing for $1,300.
Don't pay the "Brand Tax" for a less-focused product. Come talk to me at Booth B-27 & 28, Hangar B. I’ll show you the exact tech that helped me earn my wings - and how it can make your flying safer for $2,500 less than the competition; not to mention savings in installation labor.
