Features Enjoying up to 6 months of battery life between charges, a user will only have to charge their device twice a year With a waterproof rating of IP67, the Scout can be left in the rain, ridden in the rain, or get wet when washing your bike without affecting the functionality Multi-functional LED's allow the user to clearly see if their Scout is alarmed, paired and the status of the battery 25 grams, that's the equivalent weight of a single AA battery When charging Scout, there is no need to remove the unit from the bike; simply recharge via a USB C cable The alarm is impossible to ignore at 85 decibels, which is louder than a truck, but not quite as loud as a helicopter Scout attaches to your bike via the bottle cage mounts using tamper-proof security screws
