This is exactly the same battery as the DigiTrak® SuperCell™ that retails for $175. Offered for sale at almost half the price. Compatible with most DigiTrak® and Ditch Witch® transmitters. Primarily used for tough boring conditions and long rocky bores. Save time by not having to pull back rods and change transmitter batteries during long, hard bores. Battery life depends on the transmitter being used. Refer to transmitter manufacturer's specifications for more information.
