Computech or altronicrs perform air?
 

Which one to buy and why?

Re: Computech or altronicrs perform air?
 

If you are talking trailer based, I asked the same questions 2 months ago to Don Higgins. If you are using Crewchief Pro software, they have to do something different to the Computech or it does not send updated weather info. I replaced my Altronics Performaire Pc with the Performaire Pro. Based on Don’s recommendation.

How about some more comments or recommendations for handheld units from Racers, the people that have them and use them. Thanks.

I like my Kestral 5100...graphs, takes readings as often as you program it ..wind meter so you can measure wind at track level...very nice unit....if you get link option it will transmit to phone within bluetooth range...

i have the Altronics PC system. If you already have a lap top computer the price is real reasonable. If I had to do it over again I would have gotten the paging option. its cheaper when you get it with the system when you first purchase it. Customer service is good and they respond on the weekends if you are at the track and have issues. I use their Raceworks software and it is pretty user friendly. Crew Cheif pro is also available

This is me, I had the trailer based Altronics PC program for years. I upgraded to the new hardware and a pager. I also use the Crew Chief Pro. Still learning the software.

Previously I was just looking to document the conditions. Now I can spend 45 minutes in the lanes waiting to run. Have seen some big changes while waiting.

Fred and Don at both companies have been great at answering my stupid questions.

If anyone wants to learn the science and intricacies behind ET correction and prediction based on weather, you need to get Patrick Hale's book titled: "Motorsports Standard Atmosphere and Weather Correction Methods".

I highly recommend the Kestrel 5100 weather station. It is highly accurate, portable, and has a link option. My employer supplies Kestrel equipment to various branches of the military and is used by snipers in the field for correcting their scopes based on temperature and wind.

Great luck with my Computech Race Air Pro. It gets updated every few years also.
