(More customer reviews)My boat had an old pitot speed sensor hooked up to a speedometer that didn't show speed below 10mph which can be fast in no-wake zones.I purchased the Humminbird 525 fishfinder and added this speed sensor which works really well as low as 2mph.The fishfinder hooks up with a cable keyed to fit in the right spot (idiot proof) and the unit is plug and play.The instruction stated to use 5/8" drill bit on the transom, but you could use a 1/2" and save the trouble of looking for the larger bit.This product is great!
