Subsite Electronics, a Charles Machine Works Company, is rolling out TSR mobile software, giving drillers an opportunity to download horizontal directional drilling (HDD) bore information from the Subsite TK Series HDD Guidance System directly to smartphones and tablets.

“The TSR mobile software speeds production by replacing the manual bore log, which is time-consuming and creates the opportunity for error,” says John Bieberdorf, product manager, HDD guidance systems, Subsite Electronics. “From the business aspect, sending reports directly from the field can improve cash flow because many customers will not pay for a project until as-builts are provided.”

With TSR mobile software, drillers can generate as-built reports as soon as the pilot bore is completed. Information can be sent to and viewed on Android mobile phones and tablets, as well as Windows-based computers and Mac OSX. 

TSR mobile software is shipped with each TK HDD guidance system sold and can be downloaded at no cost from the Subsite Electronics website at for use with TK equipment already in service.

TSR mobile software profiles include a pitch-based graph of bore data. To log a data point, the operator simply pushes a button on the guidance system. The profile is calculated by rod distance as the downhole tool progresses, documenting tool location and pitch, as well as field terrain. Reports can be immediately e-mailed to the office or the customer via smartphone or tablet.

TK HDD guidance systems are available in three models to fit specific drilling needs. TK systems filter out signal interference present on many work sites to provide accurate tracking of the bore head. The TK Series is the only HDD guidance system with dual locating modes (“walkover” and “drill-to”). Easy-to-understand, high-contrast graphics are legible even in bright light, and the TSR remote display can be mounted on the drilling unit to suit the driller’s preferences.
