Waterproof Digital Scale with Ruler - The new digital scale with ruler is great for fishing, but great for other uses. Use it to weigh maximum grip before your next flight, or to check luggage weight. A handy retractable ruler is included so you can measure the size of the box and then verify the weight to save on shipping costs. ACCURACY AND HIGH CAPACITY - The new digital scale with ruler is extremely precise, accurate to 1/10 pound or full ounce increments. The scale will also measure in kilograms to two decimal places. You'll get accurate weight readings up to 110 lbs or 50 kg. Use the 38" retractable tape measure to measure fish length or package size. Memory Function - Quickly and accurately weigh fish or other items in pounds and ounces or kilograms. In addition, there is a memory function to store 9 different weights at any time and refer to them. Lightweight and Durable Handle - The handle is made of high strength ABS, very light yet very strong. The handle and sides of the scale are coated with a non-slip TPR coating, giving you a firm grip when lifting and weighing fish or other items. The wide handle opening is convenient for all hand sizes, making it easy to hold with or without gloves. SMALL SIZE, LARGE FUNCTIONALITY - The scale measures just 5.6 inches long x 3.8 inches wide x 1.2 inches thick and weighs just over 6 ounces (about 170.1 grams). Other great features include a backlit digital display, memory function, auto shut off after 4 minutes to save battery and 2 AAA batteries so it's always ready to use.
