Here are some links to gear and sites that I use a lot - gear, learning, reference, whatever...
Camera Trapping:
I use Cognisys gear almost exclusively for my camera trapping requirements. While I am close friends with the people in the company, and receive the odd prototype to test in the field, I insist on paying for all my gear. I stand by this company and its products 100%. Their website not only has their products, but tons of How-To video tutorials, articles, images and explanations. If you are remotely interested in camera-trapping, this site is a must-visit.
High Speed Imaging Solutions:
I am officially 'retired', though I do have a business - Roy Dunn Photography. Under that business name, I am a consultant to a number of companies, and by far the most fun I have is with Hadland Imaging. Hadland is a company that provides complete high speed imaging solutions: Video cameras that can achieve frame rates as high as 10 million frames per second, High Intensity light sources, Lasers, Flash X-Ray machines, Thermal imaging cameras, Data acquisition and Control environments, Flight Followers (Projectile Tracking) as well as software for simple to complex motion analysis. Oh, and 2D and 3D DIC (Digital Image Correlation), PIV (Particle image velocimetry). Apart from detailed product listings, the Hadland website has some of the coolest high speed video clips available on the internet. You can spend hours being mesmerized - don't say I didn't warn you...
Business Insurance:
Business insurance is important for photographers, and I get asked all the time. I use Hiscox. While I have never had to make a claim, their reputation and coverage is excellent.
I mentioned I use Sony gear for most of my work. In fact everything except stills image camera trapping (and even then, sometimes). Sony mirrorless cameras are incredibly powerful machines, and they sure do have a learning curve. In my many decades of photography, I have spent easily into the hundreds of thousands of dollars on gear. None of that money was better spent than on my subscription to the Patreon site of a Sony Ambassador, Mark Galer. He lives and works in my old home town of Melbourne in Australia. He knows the Sony system inside out, is a detail and fact-oriented teacher and is a phenomenal photographer. A perfect mix. If you have any inkling towards a Sony camera, look him up on Youtube, or even better subscribe to his Patreon site. I promise you, there will be more useful information that you can handle.
markgaler.com is his own website - you can access all he does from there.
