All the products (dual battery kit, SBI dual battery isolator and underground wire break locator) available through this site have been used by us personally and proven through application to be good products that truly do what they are suppose to do. You will find videos and directions for using these products as we have used them.
We are out of stock for DFNA 3048 until 4/27 I work with invisble type fencing for dogs and have found this "null" type locator to be extremely effective in locating wire breaks and faults in these underground systems. This simple system works well for tracking wires underground and behind walls.
A SBI is the ultra-simple and most technologically advanced method of automatic battery isolation system. These units can be installed between batteries with a common ground to automatically control the charging process to the batteries but continue to provide isolation of them when a charging source is unavailable.
This is the perfect kit to not only connect that second battery under the hood of your Truck or Jeep but it also includes the TRUE Smart Battery Isolator to automatically control the charging of the second battery while providing voltage triggered isolation of the primary battery to reserve it's charge for vehicle starting and primary operations.
