PetSafe Wireless Fence Extra Base Unit, Stay & Play Compact Transmitter, 3/4 Acre

PetSafe Stay & Play Compact Wireless Fence Extra Base Unit is an add-on transmitter for extending a compatible wireless fence with a circular boundary covering up to 3/4 acre (0.30 hectare), or 22–105 ft (6.7–32 m) in diameter.

• Additional circular coverage up to 3/4 acre — expands the play area of a compatible PetSafe fence.
• LCD boundary display and warning indicators — check the area’s diameter and see when the system reports an error.
• PetSafe’s smallest, most compact transmitter — sits on a tabletop or countertop indoors.
• Portable design with an outlet required — bring the transmitter along for camping, RV trips, or vacation stays.
• No digging or wire to bury; setup takes a few hours — create a boundary without installing buried wire.

This extra base unit is made for dog owners who want to extend an existing compatible PetSafe wireless fence or use a familiar system while away from home. The transmitter creates a circular play boundary, while its display makes it easier to adjust the boundary area and monitor system warnings. For travel use, it needs to be placed indoors near an electrical outlet, and dogs need their own compatible receiver collar to use the fence.

How much extra play area does the transmitter create?

The extra transmitter adds a circular wireless boundary of up to 3/4 acre, with a diameter ranging from 22 to 105 ft. Its LCD display shows the boundary diameter, so you can adjust the area to suit the space where your dog will play. PetSafe’s proprietary circular boundary is designed to gently guide your dog back toward the play area.

• The added boundary is circular in shape.
• The display includes warning indicators for wireless fence system errors.

Which PetSafe wireless fences work with this extra base?

This transmitter works with four compatible PetSafe wireless fence systems. It is an add-on for use with an existing system, not a standalone receiver collar; each pet needs a compatible collar of their own.

• Stay & Play Compact Wireless Fence
• Stay & Play Wireless Fence for Stubborn Dogs
• Stay & Play Wireless Fence with Replaceable Battery Collar
• Wireless Pet Containment System

Can I use the transmitter when traveling with my dog?

Yes. Its compact, portable design makes it suitable to pack for camping, RV trips, or a vacation rental. At your destination, place the transmitter indoors and near an outlet so it can operate. Bring training flags to help your dog learn the boundary in a new setting.

• The transmitter is intended to sit on an indoor tabletop or countertop.
• An electrical outlet must be nearby at the travel location.
• Each dog using the fence needs a compatible receiver collar.

Does setting up the extra transmitter require buried wire?

No. The wireless fence setup needs no digging and no wire to bury, and setup takes a few hours. The boundary is created wirelessly by the transmitter, so the additional coverage does not depend on installing a buried boundary wire.

• Use it as an additional transmitter with a compatible existing PetSafe fence.
• Bring training flags when introducing your dog to the boundary away from home.

This extra base unit is best suited to dog owners who already use one of the compatible PetSafe wireless fence systems and want more circular play coverage at home or while traveling. It is an add-on transmitter rather than an extra receiver collar, and it requires an indoor location with an outlet nearby. For compatible systems, it adds a portable wireless boundary without buried-wire installation.
