Does it make sense to switch to a Derbys Pet Fence if I already have an Invisible Fence® system?
It depends. Because of the expensive battery requirements of most other systems and our generous buy-back program, it actually makes sense to switch in most cases. The one-time cost for switching over is soon paid back to you because you no longer have to buy expensive batteries (at $16 each – every 3 or 4 months). The more dogs you have, the more quickly this payback occurs. Often, in less than 3 or 4 years, you will be ahead of the game financially by letting us upgrade your system to a Derby’s Pet Fence system. With four dogs or more, that payback time is less than 3 years! In addition to the cost savings – you will get several other features that will be a step-up from what you currently have. If you are adding a new dog to your pack – the payback is almost immediate because of the high price that Invisible Fence® charges for a new collar. It’s a “no-brainer” to switch from Invisible Fence® to a Derby’s Pet Fence in this situation.
