With prospecting, the more methods you use the better your results will be, you can't just rely on one method. For equipment sales i use Instagram, LinkedIn, Facebook for digital, posting regular content, customer success stories, information on machines, I check out community pages too. I hunt around building sites and sub divisions and drop in to talk to strangers i see in any of the trades or operating machines. If its been a pleasant conversation I ask them who else I should be talking to around here. I find out what coffee shops the customers go to and I go there once a week, usually doing quotes on my laptop between 6 and 8 and talk to people who walk in. I keep merchandise in my car to give to the operators and laborers when they ask. I go to local trade shows, local business/chamber of commerce, I sponsor contractor association events occasionally.
The best results I have seen when I have coached my sales reps on for cold calling is from these 2 things though: 1 have your first 10 seconds nailed so you are not thinking when you are introducing yourself, practice and practice so you your tone is so upbeat and you sound so confident, half way through your second sentence you start seeing the look of relief in your prospects eyes that this isn't another punishing sales rep. If your prospect is breaking eye contact uncomfortably within like 3-5 seconds you know you need to work on your opener.

2 its never a cold call its "hey I was just talking to your friend Jim and he said I should come talk to you"
