I was told in my last post regarding hydrophobic coating on Pentax dcf sp binos compared to RAINGAURD on Bushnell Legends that the RAINGAURD had no merit and that the lenses on Bushnell legends will fog up and will shed water no better than any other bino or scope lens on any other brand of bino or scope. Is that true? Is it just a gimmik? Can anyone tell me if they own these binos and whether or not they could tell if it helped much having the RAINGAURD?

I posted this already in the thread where you were asking about comparing the Bushnell Legend against the Pentax DCF SP but, I will copy it here as it relates directly to this question as well.

  • temperatures ranging from over 100 degrees to well below freezing.
  • wind speeds from dead still to so strong I could barely stand up.
  • painfully bright sun to totally black overcast skies.
  • pouring rain, driving sleet, and near white-out snow.

During this time, both the Bushnell products performed wonderfully.  They provided bright, clear images and were an absolute joy to use. However, I also observed no advantage whatsoever to the supposed "hydrophobic" coatings. 

  • When other optics fogged, so did the Bushnells. 
  • The Bushnells required an equal amount of time for this fogging to clear.
  • When rained upon the Bushnells did not cause the water to form any larger size of drops, nor did these drops slide off the glass any easier/faster.  Thus the level of distortion caused by the rain was the same.

In short, while I really, really like these Bushnells, the RainGaurd portion of their design has proven to be nothing but an advertising gimick.

Quote In all honesty I cannot remember a situation where either fogged up to the point where I had an extremely difficult time using them. You can chalk that up to the hydrophobic coating if you like but I did not really notice a difference between those two and any of the other bins I have owned in this regard.

 

Same here as lucznik. That applies to both the Pentaxs and the Bushnells. In my opinion there was no noticeable difference between those two bins and any of the others I have owned in terms of their ability to function with fogged lenses.

I have the Bushnell elites 8X43 and a 8-9 elite 4200 and 3200 rifle scopes. I have done alot of testing and it does work very well. I have compared it to my zeiss conquest on a 20 degree day and breathed heavily into the scope lens. You could not see a thing through the zeiss and the elite had no change in clarity. Really hard to believe how well it works. It will look like it is fogged up but when you pull it up to look through it you don't see the fog.

I saw the fog.

 

I suppose that under ideal circumstances these coatings might work better than at other times.  (I can't think of why this would be but, I'm willing to keep an open mind to the possibility.)  They have not worked at all for me during this year's hunting so-far.

 

Which is not to say that I am dissapointed with the Bushnell products.  I am absolutely thrilled with my Elite binocular (and the riflescope is not slouch either though, I would like it to have more magnification.) They are as bright and clear (if not more so) than any other optic used and they performed wonderfully in all circumstances.  All I'm saying is that this particular feature (RainGaurd) did not work as advertised and certainly did not offer any advantage over the other optics in use at the same times.

I can't say that I recall exactly what Bushnell claimed the Rainguard coatings did, but if they stated that rain and fog were a thing of the past or that moisture would avoid these coatings like grim death then I would have to say that they were abit over zealous. I will say that I think that the Rainguard coatings did help, not eliminate all together. I say this after owning 6 4200 riflescopes and a pair of Discoverer 10x42's and an Elite 15-45 spotter.

It's a bunch of baloney.

I would be very cautious with opinions that sound like hunting magazine advertising.

These days there is a new advertising strategy: people are paid to advertise products and services through person to person conversations and web blogging, without the target audience knowing. 

It's physics: blow warm moist air on a cold surface and you get condensation; rain on a binocular and you get rain drops on lenses.

i will say, with my experience w/ the elite 4200's - they do seem to bead water better.

 

i have hunted in the pouring rain and still had a nice sharp view - kind of like "rain-x" for your windshield.

 

i think the coating adds to the clarity and brightness as well.

 

GREAT scope/bino for the money.  i replaced a zeiss conquest w/ one of these on my sako.

 

good luck.
