I got my new 705 the other day and took it out to a local park (pretty trashy). It drove me nuts. I'm not sure if I had it set up the right way. I'm going out today and try it again maybe using only 4 tones. I have to get used to all the settings. I have read the ebook and the manual several times but it's still a little confusing. I'm used to the Ace 250 which is turn on and go. I guess it will be practice, practice, practice.
