Torpedo: impact of lure on depth

While working on adding Torpedo Deep Sea diver, an abandoned divers but that some of you could still have and use, I found this advice from the company:

Lures and dodgers/flasher/rotators all have drag. A 4-inch lure will cause your presentation to lose two feet of depth,  a magnum spoon will lose 5 feet of depth and dodgers/flasher/rotators will lose 7 feet of depth. This is important information when  making precise depth presentation.

As it is interesting for accurate presentation, I updated the interface for the Torpedos to add this new parameters:

  • 4″ lure
  • magnum spoon
  • dodger, flasher or rotator.

 

Magnum Dipsy : data for O’Ring

After having dowloaded the last version, Malcolm wrote to says that the data for the Magnum Dipsy with O’Ring was missing. It was true that the switch was enabled on the user interface but it was inactive. As Malcolm said it would be useful, I search in my library to find out if I had this chart and most of them was only showing the basic length for depth. I finally found a photo of the packaging with the full chart. It is already added and will be available in the next release.

Testing, Testing, Testing

Most of the calculations were 10 years old and even if we rewrote them quite a few times in different programming languages, they were fairly sure. BUT we finally discovered a few mistakes like the Dipsy Mini going down 40 feet 🙁 or the BigJon sizes mixed. So we decided to setup a full testing procedure. For each of the divers, this system tests each model for basic settings : low depth and the deeper, plate position or line strength, and speed. For each model, some specific testing are done like the many speeds of Torpedos or O-Ring and Fireline. 

The test is written by settings the parameters and the given length from the manufacturer documentation, and automatically comparing the result of the calculation function. IE if the manufacturer says that the Dipsy Driver #1 at 2.2MPH needs 16 feet of line to reach 10′ with the plate on center, we enter these parameters and check if the app gives the right length. Then we test with the plate on 3, and compare the result with the true value of 30, and do another test at 70′, plate on center and O’Ring to check the 150. 

Now before any release, these complete tests are run to ensure that we show the right trolling line length.

More new functions: memory

Most of the time, the app was keeping the current settings when you were switching to answer a call or check your mails. But sometimes, it was loosing the current length of line calculation. Another case where this could be useful, is the cas where you are fishing 2 different divers to get to different depths. 

At the end, it is more to remember where I intended to fish than the real length of line.

Anyway, now, the app keep track of your latest request and it’s cool.

 

 

Plate drag

The first and second versions used 2 simple arrows to set up the dive direction plate position. It was for simplicity and usefulness. Driving a boat on the Great Lakes is not an easy feat and if you use an app at the same time, it must be quick and simple. Ten years later, everybody has got time to train and get better with drags swipes. the new version adds this move to set up the directional plate. BTW to not have it would make the app an old and odd design.
