If one has a surveyed depth and radio located point on surface, but has to dig a horizontally inclined tunnel to the point underground, how does one stay on track to the point. Ie; xM distance and xM depth?
One could go over/under or to the sides of the surveyed point.
Is it just a question of using compass and declination or are there sophisticated items on the market, ie; Laser beams/theodolites etc?
Any help or pointers would be greatly appreciated. Have tried creg but no lick so far?
