At its heart, the Garmin Forerunner 235 is a running watch. When you look deeper it has a wealth of features at a great price point. The forerunner 235 is also a standalone smartwatch so you don’t need to pair it with a phone to use a lot of features. On this page, I am going to cover some of the common problems and frequently asked questions. If you are considering buying one or you have a problem I hope to answer all the usual questions. If you have a question please contact me and I will endeavor to get an answer.
The Garmin Forerunner 235 was released in 2015 so its not a new device but when you consider it has built in GPS, up to 9 days of battery and a color screen that is still stands well in comparison to newer models.
Is The Garmin Forerunner 235 Waterproof
Yes the Garmin Forerunner is waterproof. The rating is 5ATM this is equivalent to 50 meters! so swimming, diving, showering and rain are no problem! Worth noting that the heart rate monitor doesn’t work when you swim with it on.
Can I Take It Swimming
So yes you can take it swimming what are the features that specifically support swimming there is no stroke meter nor can you track distance swam indoors. The Forerunner 235 does support outdoor swimming as it uses GPS to track distance. If you are looking for a Garmin device to track your swim consider these options.
Can I Use It For Golf?
Yes but it depends on what you need from a golf watch. Like with smartphones you can download apps from Garmin Connect IQ Store. Here is an example of a golf score app you can download. The options are limited to recording scores, it doesn’t record the distance between holes or how far to the pin. If you are looking for a Garmin watch for golf then consider the Garmin Approach series.

Garmin Forerunner 230 vs 235
The main notable difference between the 230 and the 235 is that the 235 heart rate monitor works on the wrist. The 230 heart rate monitor works via a chest strap that is ONLY included in the bundle edition. Given the slight price difference, I would recommend going for the Forerunner 235 if heart rate monitoring is important to you. If you find that the wrist heart rate monitor of the 235 isn’t as accurate as you would like you can still use a compatible chest monitor with both.
