Hello all I am new to this buisness and I know my limits on what not to take on,I have cut trees for about 10 years but from the ground and I purchased a double d saddle buckingham gaffs and a wire core flip line and I am extremely wanting to learn to climb and top trees.and I watched all the videos on the site and it is something that I want to learn,I have been soaking up as much info as possible before I get into it,I have tried to climb and went fairley well but I don't know anything about the rope climbing or the knots used to do this.but after watching the videos it looks to me that this is something that I need to learn,are there any videos online that explains and shows you how to tie and use this system,because I know safety is first and formost,and I would like to get started right not wrong.
