that's interesting you do this with spoons? I was told to stick to the deep holes in August/Sept.
I have done it with the anchor mode on Baitbuckets boat and it is great! That said a sea anchor goes a long way to slowing down most drifts and for a lot less money...
has to be completely flat, no wind for me. my boats too tall and the cabin catches the wind. i do it late august into the fall near spawning grounds trying not to jig in more tha 50 foot of water. if your drifting about a half mile an hour or more ive done well hand line jigging with lead core and suttons, short leader and you can feel the tip of the lead core just touching the bottom, its kinda inbetween a troll and a jig and used to be done on lake willoughby in vt, killer sometimes on sebago spring and fall. this doesnt work as well with a rod and you pile leadcore on the boat floor and pay it out or bring it in as needed to get that light tap tap sensation in your hand of the lead just touching the sand and you want a sandy bottom to avoid snags. i have not seen another boat do this in 20 years
