The DF2200PX is the most versatile handheld depth sounder ever produced. Not only will this depth sounder give you instant dept readings from 2.5 to 199 feet (.7 to 60.1 Meters) in 1/10th precision, but at the press of a button the display will give real time temperature (water or air) and fish readings. Use it in the winter to shoot through ice before cutting your hole. Use it in the summer as a range finder and temperature meter while diving. Use it as a backup depth sounder on your pleasure boat or scan for channels in your dingy. No matter how you use it, the DF2200Px is the one piece of equipment you should never leave the dock without.
