Garmin Venu 1, 2, or even one of the newer Vivoactives would be great. You can get a Venu 2 for probably about $100-$130 on Facebook Marketplace right now. You can also get one of the older Garmin Forerunners for about the same price as well, if not a little cheaper

Use forerunner for swimming and it works great. So happy I no longer have to count my laps and I can just swim.

if he is working a lot in the rain, get him something with more than 2 buttons so he would be able to use the watch using only the buttons (without the touchsreen) if he needs to, something like a forerunner, or instinct (doesnt have a touch screen) or a fenix (but a fenix is one of the more expensive ones)

r/GarminWatchesApple Watch vs Garmin: Which One Actually Helps Your Health and Fitness?
9 months ago

The same I was big on the Apple ecosystem and felt like it was a cool watch just because it integrated so well, but I never even downloaded any apps for it. All I ever used it for was timers and reminders and stuff like that and basic fitness tracking, and my forerunner does all the same stuffbut way better. Should’ve switched sooner

Dito. Venu will offer a tick “sexier” display due to oled, FR will most probably go longer. Might be a case for weekend hike ;)

r/GarminWatchesToo many watch models
5 months ago

All true except advanced metrics. They are also present in Fenix (it has even more features for hiking) and Instinct. Forerunner is not more advanced. The rugedness is mostly about the bezel. In fenix and instinct it has a rim which gives extra protection to the screen. But that means rugged watches are more bulky what can be a problem in the gym. The real question is lightness of forerunner vs battery life of fenix /instinct

r/GarminWhich Garmin watch is best for hiking, gym and general daily life?
26 days ago

I have a Fenix 7 Solar because I bought a 6 Pro Solar really cheap when they were discontinued but it broke and Garmin sent me a 7 as a replacement under warranty. However the Fenix models are generally more than I feel I’d want to pay unless they are end of line so if I needed another I’d get a Forerunner that has the functions I actually use (Fenix, for example, has gold stuff. I will never play golf)

r/XXRunningWhat fitness tracking watch do you use?
11 months ago

I’ve had and loved garmin forerunners and a coros pace. Slight preference for coros over garmin for battery life. Slight preference for garmin for multi-app interoperability.  I’m actually planning to buy an Apple Watch because it’s fine as a fitness tracker and has better health tracking capabilities on top of the fitness stuff.

Depends on what you need, if it’s mainly for running, I’d go with one of the cheaper Forerunner models. An AMOLED display is a nice upgrade though. Also, definitely check the battery life if that’s important to you. I recently switched to the 965 and can say it’s been a solid watch.
