Very easy to set up and use, and also seemed very accurate in giving altitude and range of nearby aircraft. I have TIS aboard my aircraft, and the Zaon was almost always in sync with the TIS readout.

Not having direction is a negative, but you can quickly figure out if the target is approaching or receding, and scan to find the target.

This product is well worth the money if you are concerned about traffic issues and do not have TIS or other traffic avoidance products in your aircraft. It pretty much works anywhere there is radar coverage and with any airplane with a transponder.

Alerts to transponder traffic and is pretty accurate.

Battery life is short and alert could be louder. MRX comes with an inline headset adapter but I think an intercom plug would be better.

I was skeptical in purchasing this and already on 1 flight it has spotted aircraft that I couldn't see and also was very close to ATC traffic reports. As a student pilot, I feel safer flying with it.

Small size and portability!

Cables and plugs clutter up the cockpit a bit

Grest value. System already healped resolve an impending traffic conflict that was developing

Increases situational awareness significantly. Easy to use. Well worth the cost. Includes an audio feed cable for your headset... but you don't need it. It's easy to hear without it even with ANR headsets. It comes with a power cord... but again, you don't need it. The battery life is plenty long enough for a normal days flying.

The plastic case seems very sturdy, but the halves don't fit well together over the front panel. It's not really even very noticeable... just nit picking. Also, getting the batteries out is a bit of a challenge. I use the corner of the battery compartment door to pry them out. It works well.

Flying with it is now a personal minimum.

Small and Light Weight - Easily portable from aircraft to Aircraft.

Easy to Use - even if you just scan the user manual, anyone with the slightest tech savvy can figure it out in minutes, it's very basic for the amount of tech it involves.

Battery powered - No dealing with cumbersome wires for cigarette adapters (though one is included)

No Bearing Information - Range and Altitude only, this makes it sort of a guessing game as to where to look.

Battery Powered - make sure you carry some good spare AA batteries with you in case you need them.

Not really a con, but due to understandable system limitations, it cant pick up aircraft that are non-transponder or transponder off, so dont expect it to show every single aircraft out there.

As a CFI at a small but busy airport, I'm in and out of various airplanes for several hours every single day. No traffic avoidance device out there from GA level to Airline level is a substitute for pilot's eyes and vigilance in scanning for traffic... but it is great to have a PCAS aboard to help with situational awareness. If the MRX device saves it's owner from ONE mid-air collision... it has paid for itself a million times over.

The first thing i learned from the MRX... is that its amazing how many airplanes out there you never see or never would have seen!

Unfortunately i have not had a chance to use it in an area of high traffic density like Dallas or Houston yet, but so far in only a few days of owning an MRX, it has pointed out about half a dozen aircraft that i would have likely NEVER seen.

Its easy to use, you dont have to constantly fidget with it, it is highly portable, and for someone like me who climbs into and out of a hand full of different planes every day... i would consider this an essential piece of equipment. it's like having a friend in the back seat with "spider sense" that every once in a while he says "hey... there is an airplane pretty close by, better increase your traffic scan."

some might think it would contribute to pilot complacency, to the contrary, it has made me MORE vigilant in my traffic scan because im actually a little excited to see traffic visually now and compare it to the indication on the MRX while trying to estimate how accurate the device is. - and let me assure you, for the money, it appears to be VERY accurate by my visual estimation of range and altitude of detected aircraft.

If you're thinking about buying an MRX... stop thinking, and click "Add to Cart" right this second... In the entire span of my aviation career i would rate this as one of the very best general aviation purchases i have ever made.

very easy to use.
I am a student pilot and when used it on my third lesson, my instructor told me that it could not detect aircrafts with no transponders. I replied that I knew that, but I wanted to have a pair of extra "eyeballs" anyway to help us with the traffic.
And while I have the responsibility to see and avoid, I feel more comfortable with it, because it helps to see aircrafts that we can see only later.
And my instructor liked it and told me that it was pretty accurate.
So now I always fly with it.
I would love to have buyed it at a lower price, but I think of it as an insurance and for the extra security that brings it is worth the money paid.

Limited benefit

It seem to work sometimes, other times it will miss an aircraft that I can actually see. The unrelible nature of this product make me nervious. That may be a good thing, but its not doing what I bought it for. This was my second one and it acted just like the first. I think it misses about half of the aircraft.

I really wish this was more reliable. I thought about buying the more expensive one but if it functions the same way I wouldn't feel good about it in the cockpit.

The first (and only) time I've used the PCAS, I was completing the my IFR training. The alerts were timely and accurate compared to the ATC alerts I was also receiving.

( No Cons Listed From Reviewer )

After using the PCAS one time for two hours, I'm not sure how to rate Durability and Reliability.

Used on a recent X-Ctry over 312 NM from Virginia to New Jersey and it worked as advertised. Can't beat the price for benefit.

Remember it cannot detect aircraft without a transponder and may not detect those with one based on certain attitudes or if they have a dirty Transponder antenna. Gave it 4/5 because it had some trouble detecting my Transponder code a few times but picked it up after a while. I understand Tech support can help with settings if this persists.

Works great! When sightseeing in Hawaii, hearing nearby traffic and trying to find them is nerve wracking. Some areas are heavily traveled such as the north shore of Molokai, which has no radar coverage, so it's all radios and looking. However, with the Zaon, it's so much better to know how far away traffic is. I had no idea so much traffic was around. I used to just fly along thinking I was the only one in an area. The altitude function did not seem accurate for some traffic.

I worried about the lack of ability to know the location of the traffic since the more expensive model would tell you the quadrant. However, as I used this product, I realized that all I needed to know was if it was closing on me, which means it was in front of me. If the distance remained constant, then I was following it or it was following me, certainly no threat. If the distance was increasing, then it was going away.

The headset function was not necessary as the flashing alert while on the top of the instrument brow will catch your attention easily.

My unit was okay in construction, unlike the other reviews I read. Battery door was fine.

Compact, rugged plastic case, light weight, simple operation - brilliant!

None that I'm aware of.

Took off for a cross country and during climb out a Skyhawk flew past at 500 feet horizontal without a word on the Comm! Caught my self and my instructor by surprise is an understatement. He's a 40 year pilot who then told me that is his greatest fear was a midair. That was after a previous flight when we had an inflight emergency and were about to land in a farmers field in Maine. Naturally, I ran out a bought this baby after reading the review in Pilot. Seems to be working well. now I just hope everyone turns on the transponder to Alt!

Creates a heightened awareness when it begins indicating. You can quickly determine if threat is moving away from you just by noting the distance from the target.

Altitude indications seem accurate for the target.

If plugged in to the intercom, the audible allert will definately get your attention when the target is an imminent threat.

Worth the cost, and I think a better value than the more high priced unit. I sent the big brother unit back.

12 Volt wiring is cheap.

compact size, ease of use right out of the box

price is little hefty for this plastic unit, brand new out of the box noticed Battery compartment leads and Battery compartment cover was broken, Thank God sporty's replaced broken unit with out asking a single question.

Initially was debating weather to buy or not cause of the price, but once getting used to this felt life is worth than price.

Didn't expect the device to save my life the first flight out of the box...but it likely did...(I was just curious to see if the thing worked)
Flying above the mouth of a canyon triangulated between three airports at 11,000 ft I was headed south-bound and climbing monitoring two of the three local frequencies. The MRX picked up inbound traffic at 5 nm 20+ and descending, which quickly came within 2 nm and 10+. A quick scan of the horizon revealed a Cessna 421 coming from our 3 o'clock out of a setting sun descending into the unmonitored airfield at our 9 o'clock. We quickly arrested our climb just in time to see him slip 500 ft. overhead at 200 + kts. The MRX gave us the precious seconds that we needed to make sure a possible catastrophe was merely a close call. (Did I mention I had my mother in the airplane?)
