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.













For sure a Garmin Fenix3 HR!!!
I would likely get PowerTap P1 pedals or a pair of shoes with a power meter, if any are released shortly!
The GoPro HERO5 would be amazing. It would be just for the fun of recording the crazy things we plan to do this coming year.
A GoPro Hero 5 to take great underwater pics during vacation.

I’d still love a mapping cycling GPS in the Garmin Edge family
I would buy the Garmin Index Smart Scale. Ya know…just to make sure I didn’t eat too many Christmas cookies.

Wait until he learns what a power meter is!!!
Maybe a polar v900 if that’s launched at ces 17, otherwise a forerunner 735/630

I’d pick up a pair of the PowerTap P1 pedals and finally start training with power.
