Oli don't listen to Budman he just doesn't know what works
Get yourself some fishing line and lighter line will do and then get yourself some flat back spray paint and some green in there also to give it that camouflage look
When you bring it out to your garden invert the fence meaning the part closer to the grow should be closer to the middle of the garden and the upper part should be worked outward in a inverted staircase if you will up to 7 to 8 feet for good measure and I would make a very complex web of fishing line surround the garden to keep them at bay up to 8 feet again to keep them from jumping your work
Good luck this has worked for me in the past just make sure you leave a way in and out if you will visiting the garden often
