Ok..I've been running these dang Mega units around and around trying to rationalize why I need one so bad. One big question I have is this, I currently use a 1198 and use it on 455khz to utilize SI. Why then is the Mega frequency so much better when I don't use the 800Khz that my unit already has? Is it the higher screen resolution, faster processor, or just a combination of all that make the new Mega units worth the money? Most scanning I do is at 75 feet or less (150 feet total). Do those of you that have the Mega units actually use the high frequency that much while scanning?
