Reinforced or flexible cables, such as braided or thickly insulated ones, prevent damage from bending or pulling. Weather-resistant designs protect internal components from dust, moisture, and harsh conditions. The construction should include clearly labeled buttons and a high-resolution display that resists scratches and impacts. Additionally, a compact, ergonomic design is essential for comfortable handling during extended use. Investing in a durable scanner ensures longevity and reliable performance, saving you money and frustration in the long run.
