5 Easy Steps To The Site
In Depth Product Reviews
You probably stumbled upon here looking for a review of a sports gadget. If you’re trying to decide which unit to buy – check out my in-depth reviews section. Some reviews are over 60 pages long when printed out, with hundreds of photos! I aim to leave no stone unturned.
Read My Sports Gadget Recommendations.
Here’s my most recent GPS watch guide here, and cycling GPS computers here. Plus there are smart trainers here, all in these guides cover almost every category of sports gadgets out there. Looking for the equipment I use day-to-day? I also just put together my complete ‘Gear I Use’ equipment list, from swim to bike to run and everything in between (plus a few extra things). And to compliment that, here’s The Girl’s (my wife’s) list. Enjoy, and thanks for stopping by!
Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.
My Photography Gear: The Cameras/Drones/Action Cams I Use Daily
The most common question I receive outside of the “what’s the best GPS watch for me” variant, are photography-esq based. So in efforts to combat the amount of emails I need to sort through on a daily basis, I’ve complied this “My Photography Gear” post for your curious minds (including drones & action cams!)! It’s a nice break from the day-to-day sports-tech talk, and I hope you get something out of it!
The Swim/Bike/Run Gear I Use List
Many readers stumble into my website in search of information on the latest and greatest sports tech products. But at the end of the day, you might just be wondering “What does Ray use when not testing new products?”. So here is the most up to date list of products I like and fit the bill for me and my training needs best! DC Rainmaker 2024 swim, bike, run, and general gear list. But wait, are you a female and feel like these things might not apply to you? If that’s the case (but certainly not saying my choices aren’t good for women), and you just want to see a different gear junkies “picks”, check out The Girl’s Gear Guide too.
