Sun Slip-On Wrist Compass

The compass works. It points in the right direction and it fits snugly in the strap of my watch and it also glows.

I'd just received this slip on compass, so can't properly report on any long term durability or reliability. What I can share is that, out of the box, the compass is functional and relatively accurate. Currently clear with no bubbles. It will slip on easily and perfectly onto a majority of 22mm NATO/G10 styled straps. Any smaller and there may be a bit of play. With a bit of effort, I can squeeze this compass onto a couple of my 24mm Zulu styled straps as well. It is a closed system, so slip on versus clip on to straps. Lume is okay. Hope this info helps.

幅20mmのマジックテープ式の結束バンドに通して、ハンドルに取り付ければ簡単に自転車にコンパスが取り付けられます。あまりにも重力方向に対して傾くと機能しませんが、大体傾きがなければ動きます。また、空気が入ってませんので、走行中にカタカタ言うこともありません。 精度コメントはほかの方に譲りますが、コンパスは磁石ですので、鉄ハンドルはやめたほうが。私はアルミのドロップハンドルに取り付けてます。

Great until it isn’t. Does not like the cold. Lasted one season. Bubble formed at -20C and just got bigger when it warmed up. Never cleared.

本格的なモノではない
