also the new ced 7000's have a built in "RO" mode that disables all the gadgets and makes it a basic timer, very nice to have for "club" timers. I have sent two of the yellow boxes back to get fixed, neither would work right, miss shots, etc. and adjusting them did not help.... we now have 4 ced 7000's at our club and have had only one issue and ced had a new timer in our hands in under 2 weeks from the date of mailing.
(issue with the 7000 we had was that the top start button stopped working, seemed the switch soldered onto the circut board broke off, everything else worked, just could not use the top start button)
(issue with the RU Readies was that they would miss shot's, they started to be finiky and both of our units would eat 9 volt batteries like they where going out of style, before sending them back they would drain a 9volt in one night., adjusting the sensitivity seemed to not do anything.... so we returned them to see if they could be refurb'ed, that was 3 months ago)
