i had the same problem in eastern ky when i first started nightstalking i tied a light to the front of my boat and one to the rear. but i tried something different and wala it works i drop my 1st light as deep as my chord will let me (about 12 to 15 ft) and then i drop another light right on top of the 1st one (only about 4 to 6 ft) i dont know why but when i changed it seems i can catch fish all night and all around the boat. oh yeah as per the experiment from eddiebhome. nice thinking ill have to try that in my home lake
EAT, SLEEP, FISH AND LOVE THY WIFE
