ADMIN – Hi Krystal,

Flag only containment works with trained dogs but is of course not as reliable because eventually the dogs figure out there is no correction associated with these flags. I would only use it when the dogs are under supervision and would not use it where there is a serious safety hazard nearby, because the consequences of a slip-up are too great. All that said, lots of people use the flags when they are say camping to keep the dogs nearby. So when you finish training your dogs and pull up the flags be sure to save a few.

You can get more dog fence boundary flags in our store here: http://dogfencediy.com/store/wire/boundary-flags.html.

You can also pop down to your local hardware store and get boundary flags in the gardening of plumbing section. They use similar flags to mark pesticide application or to mark utility lines respectively. These flags look very similar to the ones used for dog fence training.

Does the Innotek SD-3000 “trainer” work without the rest of the system? For example can I take the collar and the correction device outside of the in groung fence and use it?

Several of the fences advertised on your website indicate that they cover several acres yet they only come with 1000 feet of wire. One square acre takes over 800 feet of wire so I’m not getting the relationship of wire supplied with area covered. I am assuming that the coverage is a function of wire length not area? What is the maximum length of wire that the units can handle? This is particular interest to me for the Innotek SD- 3000 if the correction device can be used outside of the fenced perimeter.

I don’t understand the “wire twisting” issue with the fences. It appears that there are 2 antennas and as long as the 2 antenna wires are not twisted it shouldn’t matter what kind of wire is used. The signal should see a stranded wire as one conductor as long as it’s not wrapped around a different antenna. My point is that stranded wire should work the same as solid wire as long as the two antennas (or +/-) are not wrapped together. Is this correct?

Thanks for taking my questions

ADMIN – Hi Karl,

1) Yes, the remote trainer works separately from the fence transmitter. You can take it and use it when you walk the dog for example.

2) Most systems come with 500 feet of wire which will cover up to 1/3 of an acre. The SD 3000 has a capacity of 5 acres. Our comparison chart shows all the yard capacities of all the in-ground fences: http://www.dogfencediy.com/reviews/. Also, here’s a chart on deciding how much extra wire you’ll need: http://www.dogfencediy.com/faqs/how-much-wire/.

3) All the 20 gauge wire we sell is solid copper core wire. The 18 gauge wire we sell is stranded. No real difference in terms of functionality. Twisted wire is simply the boundary wire twisted together. When twisted together, one twist per inch, it cancels the radio signal coming transmitting on that section of twisted wire. There is no +/- with the wire. Our twisted wire page may be useful for understanding it’s function and the only places you can use it: http://www.dogfencediy.com/installation/plan/twisted-wire/

ADMIN – Hi Gareth,

You can go down to about a foot deep (depending on your system and the amount of land you are fencing in). You turn up the boundary width, and you can also adjust the field size button to a higher setting to make the unit send out a stronger signal. Keep in mind that if you are not consistent in how deep you bury the wire, the boundary width will end up being much wider in some segments (e.g. where you have the wire running above ground) than where you have it buried deeply.
