How to tell the depth of your crank baits?

[Bassn Blvd]

I use a fine point Sharpe to write the depth on the bill or belly. But sometimes the ink comes off and I can't remember how deep they dive.  How do yall remember the depths of your cranks?

[Stasher1]

As soon as I take them out of the package I engrave the diving depth and sometimes the brand/model on the underside of the lip with one of these...

That's exactly what I do...since I have "old timers" disease.

I bought a set of German fine markers and they are better than Sharpie.  I print on the belly near the lip and it will not come off.  I think I found them at Target in pens and pencils.  Look for a small, clear, plastic case with 4 pens, red, blue, black and green.

I also engrave mine. used to sharpie them.  Sometimes the ink would wear off, so I would just find another crank in the box that was the same.  If I didn't have another crank of that brand I would find myself looking them up online.  Worst case you can just look at the lip size, it won't give exact depth but at least you can estimate.

I don't sharpie mine anymore... you can get a pretty good general idea at looking at the size of the bill

i can look at the bill and get a pretty good idea how deep it will go longer the bill the deeper she'll swim

The "look at the bill" trick works pretty good but in the interest of being excessively anal I use a permanent marker.

I cut up index cards and list the depth, brand, model # and color on it.  Put them in the tacklebox with the lure.

I write the depth on the lid or the bottom of the compartment on my okachobee flats storage box with a sharpie marker..  Working good so far!!

I also use a sharpie on the underside of the bill.

i know when i was buying the xraps i would take out the product info from its package and take it to my tackle box but of course i eventually took em out now i try the bill size but most of my are shallow runners from 0-1 to 3-6. so i can tell them apart. i dont think i have any 7-11 yet
