Pentax WG-1 GPS Optio WG-1 GPS’s. As a wetland ecologist this has been a back-up perfect camera used only 3 or 4 times. "It is waterproof, shockproof, crushproof, cold-proof and dust-proof design, along with its 14 megapixels, wide-angle 5X internal zoom lens. Practical feature is it is a rugged and compact, apparently designed to be crushproof against pressures of up to 100 kilograms (220 pounds), as well as being dustproof, waterproof up to 10 meters (33 ft), coldproof down to -10°C (14°F). Also, “shock-resistant for drops of up to 1.5 meters (5 ft).” The camera has been sitting for some time and consequently required me to purchase 2 new batteries ($24 ea. with charger + shipping)
