A hydraulic engine mount assembly includes a support bracket defining a passageway that communicates between a pair of fluid chambers formed in an elastomeric body. The first lens and the second lens are disposed in positions other than positions on an optical path of the laser light between a point of emission from the light source and a point of exit from the laser rangefinder. The battery is configured to be removable from and insertable into the battery-receiving portion while the insole is disposed within the shoe.
