TIMi indicates blasting direction with the aiming unit. Aiming can be done to free selected reference point.
Hole depth measurement displays the drilled hole depth and penetration rate. Drilling stops when set depth is achieved. System has drilling memory which contains three sets of counters: one total counters and two reset counters. Total counter holds the cumulative data over the lifetime of the instrument. The reset counters hold the cumulative data since last reset.
Optionally TIMi for inclined holes can be equipped also with GPS which is reducing drilling errors and especially directional errors of inclined holes even more. System equipped with GPS saves time and guarantees parallel direction of the holes having direct affect to fragmentation result. The drilling direction will be given once in either compass direction only or by traditional aiming device. The direction is stored and used in every hole until new direction is given. GPS aiming reduces the need to find any reference target. It works in rain, fog or other poor visibility condi tions. Random and human errors are eliminated and the accuracy is approximately 0.5°.
