Trolling with 40 jets and big boards

[dgf2250]

I've always felt the published dive curve for the trutrip 40 is incorrect. Graph it in excel and you'll see what I mean. Since the trutrip #40 is my go to diver for spoons and big boards, I just ordered a Fishhawk TD to develop my own dive curve. I'll determine the true dive curve and will post it back to this thread if it's significantly different than the one Capt Eric posted.

To test a running depth, you set the spoon and diver back the distance you want to test. You clip the FishHawk TD to the line and let it go. When you see it ‘thud’, it has reached the diver. Trip it and reel in. Max depth will be the depth the diver was running.

The manual for the TD says it goes to the foot for ‘max depth mode’. If that’s not true, this will be a bust. Nearest five feet is not adequate to develop a dive curve. I found discussion in another site where a guy doing the same thing I intend to do found it to be nearly neutrally buoyant when trolled. I think it dove to 5 feet 100 back. I’m counting on that being true. It is a 2.7 oz plastic device and is not as dense as a lead weight. I actually expect it’s drag to pull stuff higher, not deeper. We’ll see. If that manual is not correct about reading max depth to the nearest foot, I’m going to be upset
