[QUOTE="Ivan Beaver, post: 76115, member: 30"] Re: Danley SM80 and others shootout Monday January 14 at Danley in Gainesville, GA. Many people believe that if they get "a reading" it is accurate. Even on decent gear. Just look at the number of posts that have invalid Smaart curves. Just because it shows up on a screen they think it is "correct". There is a reason real gear costs real money. Now that being said-you can get some pretty decent data using phone apps and such. But it REALLY depends on the user and what they expect. Of course some people perfect results with a $2 app. So why does a real meter cost thousands of dollars to do the "same thing"? Once one starts to understand the real differences-then it should become apparent. It all comes down to what you are trying to do/accomplish at the moment. So yes they can be very useful/helpful/insightful etc. But would you be willing to sit in the witness chair against peer review of the measurements you took with your phone? Not me! As a wise man (Don Washburn) drilled into me years ago "What are you hear to do". Focus on that and what it takes to accomplish that. THere are all kinds of fun and interesting things you can do/measure-but are they really important for THE JOB AT HAND? Now I must admit that I don't always follow my own advice. When I run into an interesting situation-I often (time permitting) go a little bit further to investigate-and to use it as a learning tool. Just like at Mondays demo. When we heard a big difference with noise between the 650's, I just "had" to pull out a measurement rig-so get a better handle on what we were hearing. When used properly-various tools (even poor ones) can go a long way towards helping us to understand. But used poorly-and they mean pretty much nothing. [/QUOTE]
