I recently was involved in a deer vs motorcycle confrontation. The deer lost and the bike was wrecked. I certainly want to avoid that event from ever happening again so I am searching for devices that repel deer and small animals which are mountable on motorcycles. The devices I've seen on-line so far range from low priced whistles to more expensive electronic units. Not sure what is hype and what is fact in the ads for these devices. Does anyone have any knowledge/experience with these devices and can recommend one that really works? Thanks.
