Beginner Bracket Equipment Advice

After many years and thousands of dollars I think I have a half way decent car to start bracket racing with. My main question is in regards to equipment; specifically a weather station. Did the information that it supplied you help you choose a good dial-in, or do you run more seat of the pants?

I guess the main idea is, are the racing weather devices worth the investment of $200+, or would that money be better allocated to more fuel, entry fees, and parts. I've been running the car at test and tunes for that last few years to get a feel for it, when my schedule allowed, so I have seat time in it. Thanks for the advice!

For the digits on the car its best is 11.6 @ 115. It's a 74 Dart Sport with a 383.
If you plan on running for points/track championship type thing i would make the investment,you will have for years to work with and as already stated notes and more notes,later you may look into a predictor to go with the weather stations as well,this comes in handy when you end up having to go into competition with no time trials, i know div 1 bracket finals you time trials on 2 different days but then go out into round 1 eliminations with no time runs on that day so that information can be handy,also if you make changes on the car you kinda want to know if the change you made affected the et or is it the air.You will find there are lots of ways to lose in bracket racing i probably have found most of them already.
On the other hand if you are just starting not really sure you want to do it i'd wait and get my other things worked out like stated above alot of races are won at lost right off the line so work that tree.Our ride 72 scamp 340 for now 11.21 best et 116 far from the fastest car in the class be we get it done
