Depends on your budget? My thoughts would be either the Pro 78SE if you like the blue display or the 695SE if you like having a compass/volt meter/ and other features. Both very good models.
Stay away from Whisteler 68/78...I just returned TWO 68SE units to Amazon. They were BOTH defective right of the box. As a result, Amazon is not selling this product anymore.
From the Amazon web:
Item Under Review
While this item is available from other marketplace sellers on this page, it is not currently offered by Amazon.com because customers have told us there may be something wrong with our inventory of the item, the way we are shipping it, or the way it's described here. (Thanks for the tip!)
We're working to fix the problem as quickly as possible.
You can read my review on Amazon. Also, in that price range you will not get a decent rd. I stepped up and got Bel V995 for $199. It is money well spent as it performs as well as Escort 8500..
Welcome! Go to "Guys of Lidar" on the web and look at the radar RD test. That will change you mind I hope, do not go cheap.....
