Hello again and thanks for your replies in advance!I am in a position to purchase either an OTC or a Scanmaster.The OTC I can buy for a little less than the Scanmaster.I want a scanner of some sort to ck such things as blm,knock,tps,etc as well as read codes.I like the portable nature of the OTC.Does either have the advantage as far as what info that they will give us?All comments appreciated!
