If you are in the U.S. I would think twice before spending $8k on something like this. ADS-B has been promised nationwide over the next couple of years; offers far more for free than just lightning strikes; and should be displayable on almost any EFIS.

See link here:

Avidyne hasn't done a particularly good job letting people know about it on the marketing front, but aside from that it seems to be popular for those who want them.

Thanks Stein,

been to the website but they don't say too much with whom they interface with and not. Is the Garmin G430 and 530 part of the list.

Lastly why is this one better than the strikefinder or L3 stormscope?

My panel will consist in basically a 10 inch skyview with GPS, engine monitor and AP, GPS 695 (no WX in Brazil), sl40 and gtx327.

Thanks for the inputs

Hi Moura,

would like to hear from you what you finally decided. Did you installed it or not? How does it work? I'm just in the same position like you, planing my panel for a RV 10 Flyer, tripple Garmin G3X and there is some panel-space left for eventually a Insight Strikefinder. VFR only, that means staying out of clouds to be legal aniway. But on the other hand, if someday you got trapped by wheather this device could safe ones life, if you are able to steer aroud the worst. So, the question is: does it really work, is it worth the money, in a VFR only RV 10 ???

Default stormscope

I put nearly 6000 hours in my Bonanza equipped with a Stormscope. Yes, it really works. If other technology was not available here, one would be in my RV. The biggest benefit by far is not avoiding thunderstorms, but the confidence in flying 99% of the time knowing there is not a thunderstorm, unseen, 5 miles ahead in the haze and rain.

The Strikefinder is a very useful tool if you have no other onboard weather available. If you have NEXRAD I wouldn't install a Strikefinder. I did however fly over 1200 hours in a Beech A36 with no weather avoidance equipment other than my eyeballs and the Strikefinder (onboard NEXRAD was in its infancy then and I did not have it). One word of caution though. The Strikefinder will give a very accurate depiction of the heading of lightning strikes. However because of varying storm intensities the distance shown on the Strikefinder can be off significantly. For example if there is a very intense storm outside the range of the Strikefinder, strikes from that storm may show on the display that are radially correct, but with inaccurate distance. Also, if there are numerous strikes going on you'll need to hit the clear button relatively often as the screen will otherwise light up like a Christmas tree.

One neat feature of the Strikefinder is that you can slave it to your gyro and as you turn the strikes on the display turn too.

All in all I found the Strikefinder very useful, but like every other instrument in the panel, I did not rely solely on it. For flying in the US, the Strikefinder in conjunction with Flight Service or ATC kept me safe.

Default Avidyne storm scope

The Avidyne unit sounds interesting. Will it interface with the G3X or the AFS efises? How much does it cost?

Hi Guys,

I am also in the market for a Stormscope/Strikefinder for our RV10 which is under construction and should fly Feb 2014.

I have a Stormscope in my RV7 and have a lot of faith in it.

The Stormscope unfortunately needs a Garmin 430 (or 530) screen which I am not installing in the 10.

The 10 will only have 2 Skyviews.

The Avidyne system looks very pricey and does not say if it will work with the Skyviews.

Any further recommendations or reviews on the Strikefinder?

Thanks in advance,

You can get a standalone stormscope that doesn't require a screen.. like WX-950 or WX-1000... or one of the older units, such as WX-10 (or -11).. .we just picked up a complete WX-11 system from Sarasota for $800.. The -1000 runs in the 3-3.5k range..
