i would like to purchase either a transit or a laser level, but don't know anything about them. i don't need a deluxe new model, probably try to buy one off ebay once i know what i need.
my intentions are to use the transit to shoot elevations around my land primarily to determine runoff drainage.
also, does anybody know any good books, internet sites, reference material, etc. to educate myself about the proper methods for shooting elevations?
