Overview
The SportDOG SDF-100C is a rechargeable in-ground fence system with a waterproof collar receiver offering tone, vibrate and static correction levels, sold with 1000 feet of boundary wire and 100 flags covering up to 1 1/3 acres out of the box.
The base kit is expandable to 100 acres with additional SDF-WF wire and flag kits, and to more than one dog with extra collar receivers, so it scales beyond the starting acreage rather than being fixed to one yard size.
- 1000 ft boundary wire plus 100 flags
- Covers up to 1 1/3 acres, expandable to 100
- Rechargeable Li-Ion waterproof collar
- 2 year manufacturer warranty
Who it's for
Owners wanting a permanent, buried in-ground containment system rather than a portable or GPS-based fence, for one or more dogs on a property up to 1 1/3 acres, or larger with add-on kits. Not a fit for anyone who cannot or does not want to bury wire.
Strengths and trade-offs
Drawn from this product's published specifications.
- Escalating tone, vibrate, static correction levels
- Rechargeable Li-Ion collar, no disposable batteries
- Expandable to unlimited dogs and up to 100 acres
- Requires burying 1000 feet of boundary wire to install
- Base kit covers only 1 1/3 acres before needing add-on wire kits
Performance notes
The system escalates correction in stages, tone first, then vibration, then static, as the dog approaches the buried boundary wire, and the rechargeable lithium-ion collar avoids the need for disposable batteries common on older in-ground systems.
