The RS 300 is a great machine. You should be very happy with it. I like it better than the other brands I have. The only thing better is the RS 500 and the RS 800. Once you use the RS 800, you won't be as happy with the RS 300. The reports just look so much better. My agents and even the radon radon mitigation companies like my reports and the machines accuracy. It has helped to get me both more radon tests and a couple of full home inspections. I have pretty much retired or sold everything but my Radstars and Femto-Techs.

Good luck from the Great NW

Thanks for the response.

Just to let you know, the RS500 is being discontinued (RS300 is taking its place). The only options is the RS300 and the RS800. The RS800 is $3,000 which is out of my price range at this time. I like the rental option for the RS800 of $75.00 a month with no extra cost per monitor use.

Radalink offers a great serivce but with things slowing down (I don't see home inspections picking up to where it was the past years), there is more time for record keeping.

It's too bad they are dropping the RS 500. It has a lot more features than the RS 300. The delay feature is a great plus and the tamper feature is really nice. It takes a minute to set up, but is well worth it. The RS 800 can't be beat, but the price is hard to take. I am renting the RS 800 and love it. The RS 300 is good, but very basic. I would lease the RS 800 or find a used RS 500 to buy.

Good luck

Ollie
