First time poster here. I read this thread and decided I had to comment. As a long-time gardener I've learned how to deal with the deer. My main garden is surrounded with a 5 foot high welded wire fence. This keeps out the smaller animals and only mildly curious deer. Around the welded wire I run one strand of electric polywire fencing. It is anywhere from 3 to 5 feet high depending on the location. Deer do not like electric and after one exploratory shock they stay away. In addition I have a Contech motion activated scarecrow sprinkler
that will spray water if any deer would happen to jump into the garden. The scent-based and stationary motion objects only work for a short time until the deer figure them out. Around my orchard I have two strands of polywire electric fencing. That stops them there. My truck patch will also have electric fencing. I eventually plan to install high quality Electrobraid electric fencing. This stuff is used in Canada to keep moose off of highways and in the US southwest to stop elk. Deer should be no problem. For my wife's flowers I have found a spray that stops them cold. Tree Guard Deer Repellent contains the most bitter substance known to man, Bitrex. This is in a latex carrier so it doesn't wash off in the rain like the pepper-based sprays do. Spray this on and the deer will take one taste and leave it alone. You can't use it on edibles however. A neighbor bought some and accidently got some on his fingers and then touched his mouth. He was up all night vomiting. You can get it at this site.
Hope this information is of some help. As I've learned the hard way in gardening and farming, get your infrastructure built first and the rest will follow along.
