Bike accessories – No. 5: Garmin E800 Case

There’s no denying that the Garmin Edge 800 is an attractive and intelligent piece of kit. However it has a design flaw.

During last month’s climbing challenge I noticed that when it rained, the Garmin’s altitude readings went haywire. Typically, it stopped registering any change in elevation which was quite frustrating.

Initially I thought the device was faulty, but some Googling around revealed that the Garmin has a small hole in the back which allows an internal sensor detect atmospheric pressure and temperature. However, a small droplet of water can clog the hole and block the sensor.

However, the hole in the centre of the shot has no protection from rain

After hunting around on the interwebs, I discovered that Garmin manufacture a silicone case for the E800 which covers the offending hole, but with a groove to still allow air movement.

The groove allows air movement but runs down the body of the Garmin so there should be no way water can find its way up

Product spec – this can be ordered from Amazon but be warned, they posted it in a parcel the size of a shoe box. The case could probably be rolled to fit in a matchbox

My verdict on this accessory is that it is essential if you own a Garmin E800 and cycle in the rain. But what irks is that you shouldn’t have to hand over more cash to Garmin to resolve their own design flaw.

If you really don’t want to pay extra to protect the device, there is always the sammidge bag solution. However I was consuming two sammidge bags a month which would have equated to the cost of one Garmin silicone case in less than a year. The price you pay for living in the rainiest part of the UK…
