Garmin 010-10279-04 Water Speed Sensor 4-Pin

okay so we're going to take a quick look at how to change the battery on a gammon speed sensor now this is the sensor that you mount to the inside of the back hope and all you gonna need for this job is a small flat-head screwdriver and obviously new batteries know these take twenty thirty twos I want you battery lasts will obviously depend on how much time you spend out on your bike so the first thing you need to do is take the sensor of the rubber strap device that holds it to the hob now if you look on the back of the sensor you'll notice that there's this line that winds up with a lock and to the left of that lock is another lock that is in the unlocked position so basically all you need to do is get your screwdriver put it in that whine just pull it to the unlocked position and then on the bottom there's a little piece here that you can get your fingernail under and the battery cap
