I have a 2100 from just after they came out. Got it at Dayton Hamvention when Peet Bro still had a booth there at the old Hara Arena. So long ago i can't recall when I got it, pushing 15 years I'll bet.
I have had zero problems with their pro rain gauge (I think it is identical to the RainWise big one) and decided to go with the bigger one over the little egg shaped standard one.
Amazingly even the humidity and temp sensors are comparing closely to the other sensors I have in the same general area.
My only problem was with a lightning strike close to my house taking out lots of stuff, including the box and display. I found a 2100 on eBay that no one bought quickly and made an offer, got it and plugged in the new box and left the rest alone. Works like a champ.
I have a big display that I got for much less than their list price on eBay, also, and love it. You sure can see it across the room.
Being a hard wired unit, there is more than just slapping a instrument cluster up on the post outside and mounting the box and display inside. but it updates wind speed quickly and as I said, just keeps chugging along.
I understand that a year or so the company changed hands. I hope they will stay in business, understanding their basic design is older but does work well. And their technical support/sales have been terrific. When I had the issue with the lightning, the person on the phone was very gracious, answered questions, and won my loyalty by being so helpful.
Like anything else, times change. But things that don't change are temperature, humidity, wind values and rain. If you measure them with quality well designed components, it is the same no matter what.
The little box does have a backlight which you can leave on, and the visibility of the display seems superior to the Davis Vantage console to my eyes.
The nice thing, too, is that the Peet Console does have an output that my weather software, Weather Display, reads and is able to display and post to my web page, and hasn't been touched in maybe 5 or 7 years.
Like all stuff in the sun and weather, the plastic and cables do get nailed by radiation and over time may craze or crack, at least not seem as shiny as when I put them up. But they use UV resistant black cable and so far no failures or even appearance of having to be replaced.
The only thing I wish I had the ability to (easily) add would be solar values. I don't need UV for my personal needs, but with Davis and others there are a host of add on items from solar to leaf wetness and soil temps. I'm fascinated by the solar and inferrred clouds with my other stations that have this feature, but back when these basic stations were designed, that wasn't so much of a need, I guess.
I'd like to hear what you finally end up with as your station. If you are worried about the rain sensor, just get a Rainwise or similar bucket off eBay and wire a plug to it and set the console to accept 0.01" tips for input. By the way, I have an old original Rainwise green tipping bucket that came with my ID-5001 Heathkit which has to be 20+ years old and is still working. I did have to replace a reed switch (too bad the mercury wetted ones aren't easily available any more).
Good luck. Dale
