so THIS is the second best way to carry your GPS unit

The GPS will maintain tracking while moving and the velco makes it easy to remove and check out the GPS in a secure way

The most convenient way of course is to mount them on your handlebars, but I/we have had 3 different units quit working due to the vibration of the handlebars

I like my Garmin 650t and needed a better way to carry the GPS while backpacking

The VERY BEST way that I have found is to use an external antenna and attach it to the top side of your helmet, using Velcro with a sticky bottom

Perfect way to keep track of your Garmin

This tether kept my etrex out of the way, yet handy when I wanted to refer to it, all the way to the top of Kilimanjaro

This is a fantastic way to attach my Garmin InReach to my hiking pack's shoulder strap

If you are going through rough terrain / not on trails, then i recommend finding another way to secure as it may rip off and you could lose

I have friends that use the retactable key rings and they are not as happy, as those are either not strong enough to keep the GPS in place, or fatigues the hand / arm while holding it in an extended possition for longer periods of time
