key to catching fish on in-line spinners is to not to reel too fast.
you reel, the less effective a spinner becomes as it comes too high in
the water column and it loses it's flash.This is not a fast search
bait. Most of the time
summer, the absolute slowest speed will work best. Sometimes you can
even stop reeling for a split second and the hickup seems to
draw strikes. Try not to think of "retrieving" a spinner but rather
just getting it to "swing".
If the fish are in shallow, you can throw a BP Beadswing at them and because its just beads and blade, it comes in even slower and doesn't snag. BP spinners use a lighter, thinner wire than most and that is why they spin so easy. There is less friction between the clevis and the wire. This is key as to why they spin at such slow speeds. Smallmouth Bass in particular can not resist a slow retrieved spinner with this type of swing blade, it's almost in their genes to strike!
If its summer or fall and you need to get down deeper, try rigging a BP Spinner on a 30" flourocarbon or mono leader with just a tiny black snap( not a snap swivel) to the lure and then to a tiny black #0 or #1 crane swivel (barrel swivels will also work), add 1 small bead on the main line side( this prevents the sinker from banging on the knot and weakening it) and then a 1/8 to 1/2 oz. barrel sinker (similar to a Carolina rig). Cast it out and count it down to the desired depth (1/4 oz sinks about 1 foot per second) then start your retrieve slowly.You can't reel too slow with these BP Spinners. You can easily fish 20-30 feet deep with the right sinker. This deep method is a killer on Walleye, Smallmouth Bass, and Trout that are near bottom or suspended.
You can also use the above mentioned rigging method without a sinker but just the tiny crane swivel and a snap at the lure. Black snaps and swivels blend in best and are least likely to spook fish in clear water.This will greatly reduce line twist. Also after 10 casts or so, it is best to let the spinner unwind by holding it up high and letting it unwind. This will prevent any line problems. You can also use a very small ball bearing snap swivel if you prefer, its easier to rig but will spook the fish just a little more except in off colored water where it wont matter.
Best line options include light mono or flourocarbon in the 4lb. - 10 lb. range depending on what you are fishing for. If the line is too heavy, it just wont get down right. Another line option is superlines because they do not twist. Best to use a mono or flourocarbon leader in the rigging mention above with the superline.You can get away with a heavier pound test with the superlines because the diameters are much less than the equivalent mono
Here's a tip in general....watch the barometer. There is no more important weather factor than this. Usually a 29.8 - 30.2 reading will produce fish especially if it is moving in 1 direction or the other. A steady barometer is not the best, it makes for a pleasant day but not the best fishing. Clear bluebird skies and a high barometer ( 30.2 or higher) usually indicates post cold front conditions and fishing will be tough. Fish can still be caught but you need to alter your methods by avoiding a fast moving bait. Its best to fish very slow or with a vertical presentation (jigs) under those conditions.
Watch the moon phase. There is definitely something to this. Studies have shown that many of the world records and trophys have been caught within 3 days before and 3 days after of the full moon and 3 days before and 3 days after of the new moon. This may help with trip planning. See what phase it's in now below.
