Behold! The "Brain" of the 1st Computerized Reel.

Post by David M »

I thought a few of you might be interested in examining the "brain" of the world's first successful computerized reel, the c.1985 Daiwa PT 10E/15E. I purchased this scratched up electronic marvel for the tidy sum of two bucks, so I wasn't too shocked to find that it was DOA. I dismantled the reelbot, which by the way is no picnic, to diagnose the problem. It's the first time I've ever had to deal with grease and chips without actually being in a fast food joint. Anyway, the glitch wasn't with the button cell batteries, or the two separate power controls. Turns out the previous technofisher didn't screw down the rubber gasketed battery cover well enough, which of course lead to a case of water on the brain, and that, as they say, was that. A CPU and H20 don't mix.

Without having a fourteen year old kid around to explain to me how a circuit board with 5.18:1 gears does what it does, I turned my attention to the net. Finally, I came across an article in a mid '80s Popular Mechanics magazine which gave a simplified explanation. Here's a snippet..."The microprocessor, designed by Seiko watch engineers, simply counts the number of revolutions the reel makes in feeding out and retrieving line. It compares the line footage to a clock in order to judge speeds, and it makes allowance for the increased diameter of the spool as the line wraps around it. In order for the reel to judge how quickly the diameter increases, you have to program in the thickness of the line you're using. In return, the computer also will tell you how much line was out when a fish was hooked and how much line you have left after the unexpected break off."

I won't bore you with the details of everything this reels diminutive LCD screen can show an angler. Suffice it to say, this beeping contraption can monitor just about anything you need to know while fishing, except!, what time your wife wanted you back home from the lake for dinner. That's always a handy little tidbit of knowledge to have right there!

In reality though, when it comes to tools such as reels, simpler is usually better. If a fisherman can't intuitively sense where, and what, their lure is doing under the water, they more than likely have larger problems than trying to figure out what button they did, or didn't, push on this gadget. The computer reel was invented by Haruomi Hirose, and Takashi Atobe, both of Japan. I would imagine if any of the old Vom Hofe clan could have been around in 1985, they would've had only one word to say to these fellows about this thing...Why!

I did however selfishly envision an arcade edition reel I wished they'd produced back in the day, just to pass the time, when the fishing was a little slow. Had they actually possessed the technology, I just might have purchased one at the Daiwa computer reels original lofty price of $150-200. Goodness knows I spent many, many times that in quarters at the local video game hangouts of my youth. I digitally whipped up an old favorite of mine "Space Invaders", just for fun. You're thinking, that's one of the craziest things I've ever seen!...yeah maybe, but I've got the high score.

Entertaining, informative post--thanks, David. I mentioned it to Richard and others here in Gatlinburg as something they'll want to look at when they get back home.

YES, great report, David! I haven't had the cojones to open up my PT10E since reporting in about it on the board a couple months back. Geezer was kind enough to send me that manual for that little sucker and when I saw it was 45 pages (!) long, I kinda decided to deal with other things on my plate! .and that was the first thing I thought...Reel News Article!

Great Piece David! Amazing what those little chips can do. Today...a similar reel could probably navigate the boat, watch the weather, give ya water temps and current, cook breakfast AND tell ya what time to head in...to make the little lady happy. I was thinkin' of John E. the whole time I was reading it...and Low & Behold...there he is!

Yer done with the Kovalovsky John...?. :)

Hey Brian,Robyn,John, and Rick

Thank you guys so much, for the encouraging and kind words. It never crossed my mind that this might be worthy of the Reel News. It's certainly no Dr. Todd masterpiece, but I suppose short stories have their place. I do have more info on this reel to share, it's just that the story was turning into quite the novel, so I cut it short. I'm still honored that my little "Fake reel" article, which by the way Richard did a fantastic job of, was included in the most recent Reel News, and would be totally thrilled if this gets accepted for a future issue. I'd probably leave the Arcade reel out though, that was just for grins. Maybe a wireless fish finder display would be more appropriate, Hmmm!

Thank you Dr. Todd, that means a lot to me. I'm eagerly awaiting your convention photo's. I wish I could have made it there for the comradeship and festivities...Oh! and the reels too.

David,

Next year for sure! It's in Oshkosh, WI which isn't more than 600 miles from you I bet. Beautiful part of the country and you'll get to see some incredible reels and some great people. Look forward to seeing you there!
