Thanks John, I have those pics saved as a matter of fact. It's a slick system for running wire as you go.
Forgot to mention in my last post, Glenn, but pulling the pipe into the ground sounds like it could work as long as it went in and stayed in. I'm trying to do this without any help and am not sure how to keep feeding the pipe into the initial hole as I'm moving along.
Eric, I have a magnetic sensor from Dakota Alert. It is battery operated as opposed to "hardwired". At least the sending unit is. I used to have an infrared system but it was too hard to dial in. If it picked up a truck, it would not pick up a low car... I had it mounted all over the place and aimed across the drive at different angles, too. The unit I have now works on magnetic changes like when a car passes by and I like it better than the infrared, but it is sending me false alarms when there is thundertorm activity. I am told that by moving it into the center of my driveway I can turn down the sensitivity and get rid of a lot of these false alarms. Time will tell.
I like Dakota Alert because they have a 1000' range and a handheld receiving unit. It also doubles as a walkie-talkie and has a belt clip, too.
Doesn't fair too well with a brush hog, though, when it comes unclipped from a folded down ROPS and a low branch whacks it. /forums/images/graemlins/blush.gif
I'll try to post their website in another post. I don't want to lose what I've typed so far.
