This weeks video Captain Mark talks about how to use Torpedo Divers to solve potential tangle issues. Below is the video link http://www.torpedodivers.com/videos.asp

Here is the link, you could win an on the water Salmon Seminar Trip with Captain Mark Chmura, Ken Biemiller or Dan Keating! Or a Walleye trip with accommodations in Picton with Captain Scott Walcott. https://www.torpedodivers.com/contest.asp To show our appreciation to Anglers across the Great Lakes, there is no entry fee.

This year we will introduce Torpedo 7 strand trolling wire. It's not a new concept, it's not camo colored, in fact it's exactly the same diameter etc...as all the other 7 strand wire on the market. 30lb test, .015" diameter in 1000' spools. We will be introducing this to the Great Lakes at the MSRP of $25.00. Matthew torpedodivers.com Edit: Moved topic

I just heard the kings are turning on and water temp is 48 degrees

There is no problem with big fish using the fixed slider, we havn't lost any equipment yet, but like all fishing, equipment is lost from time to time. Once I lost a downrigger to a net but these are rare occurrences.

Cost: No Entry Fee When: From April 1st 2010 to December 31st 2010 Where: Any of the five Great Lakes including bays and rivers. Prizes: Salmon 1st 2nd and 3rd for the longest Salmon will choose a Teaching day on the water with Captain Dan Keating at Winthrop Harbor Illinois, Captain Mark Chmura at Manistee Michigan or Captain Ken Biemiller at Rochester New York. 1st place gets first choice and so on. Bring 3 friends. Walleye 1st and 2nd for the longest Walleye will choose a Teaching day on the water with Captain Bob Devine in Colchester, Ontario or one overnight accommodations plus a day on the water with Captain Scott Westcott Bay of Quinte, Ontario. 1st place gets first choice. Rules: EACH PARTICIPANT IN THE DERBY AGREES: Fish must be caught on the Great Lakes or a Great Lake river or bay. Each fish entered must be caught using a Torpedo Diver DNR and MNR Rules Apply One fish can be entered at a time. The picture must be clear and non-refutable, picture to be sent to [email protected] The picture must include a tape measure under the fish from head to tail and must include a Torpedo Diver on the tape measure for verification. Black salmon will not be eligible for entry in this Derby. You will be entitled to only one prize. No participant may win more than one prize, although contestants may enter more than one fish. If the latter fish is larger, the smaller of the fish with shorter length will be withdrawn. Your picture will be posted on the internet for others to see the Big Fish in contention. To hold the Derby officials, sponsors, their agents, servants and/or employees, harmless from any liability of any nature and kind for injuries and/or damages suffered by the entrant during the period that the Derby is held. Agrees to use good judgment in regard to existing and projected weather conditions. Listen to and heed the warnings of the U.S. Coast Guard and local weather reports, before and during each day’s fishing and, not to place in jeopardy themselves or others on the boat during the Derby. To have personal floatation devices aboard and to operate under Coast Guard regulations. A panel of two company members and two Pro-Staff will make all picture judgements and their decision will be final. In the event of a tie the first submission will be declared the winner.

We have completed a new look for 2010. The website needed to be updated as our mandate has changed to having a greater focus on educating anglers. Have a look. www.torpedodivers.com

Seems to be ok now

Appearently UTUBE is having site issues. Hopefully will be fixed soon.

We have started an educational program called Tip Of The Week. This week Captain Dan Keating shows the tip on video, next week it could be Captain Mark Chmura or Captain Ken Biemiller. I will post here when the tip has updated or you can get an email notification by registering on our site. Here is a link to this weeks Tip. http://www.torpedodivers.com/videos.asp Enjoy!

If you want to put a clip in the back you could always drill a hole in one of the fins. By clipping on the back you run the risk of wagging the weight and increasing blowback.

Here is a link to the Torpedo Diver Salmon 15 lb weight viewtopic.php?f=3&t=15571

I let the cat out of the bag at a recent seminar so figured a post was warrented. In March we will start production of a Torpedo Diver called a Salmon that has a minimum weight of 15lbs with our patent pending technology. Here is a comparison to a 10 lb fish type weight

I have seen the 83khz images and the clarity is some of the best I've ever seen.

I'll make an attempt at this. It sounds like there are 4 frequencies in question. 200khz, 132khz, 83khz and 50khz. Most sonar units do not have superhet transceivers so it is doubtful any mixing would happen. Frequencies do produce harmonics and generally the harmonics are double or half the frequency, for example 50khz would have a harmonic at 100khz and 25khz and the harmonic would cause interference. The frequencies in question look good as far as interference is concerned if the sonar element produces just one frequency. Most times a ceramic element will have more then one frequency as stray frequencies are present and this is where the crap shoot lays. The company that makes the transducer generally will use the strongest frequency for the sonar unit, for example a ceramic element has a weak frequency of 75khz, 112khz, 192khz but a very strong 132 frequency. In this case the sonar element would be used for the 132 frequency sonar units. The only way you are going to find out is to hook them all up and point the transducers at the same object from the same direction, for the purpose of testing harmonic interference this does not have to be completed in the water.

As was previously mentioned. A single beam is one beam created by a transducer element, a dual beam is two beams created by the same or separate elements. For example a 50/200khz transducer has one element that creates a cone width mode at 50khz and length mode at 200khz. The size of the beam depends on the frequency and size of the element, for example a 200khz transducer that has a 1" ceramic element has a 18 degree cone whereby a 200khz transducer that has a 2" ceramic element has a 9 degree cone. The formula to determine the cone angle is 3600/frequency/element size or 3600/200/2 = 9 degrees. It should be noted that the size of the ceramic element directly relates to the amount of power that can go through the element before cracking the element. For example a quality 1" ceramic element can handle up to 600 watts rms power before breakage occurs. A side note is the a 1" element @600 RMS would cause so much ringing that the surface clutter would be enormous and therefor large amounts of filtering would be needed, the downside to this is fish targets may also be filtered out. Once you get to 600 RMS a 2" element would be recommended. On this same thought, the larger the element the more sensitivity is available since the ringing of the element quiets at a faster pace and less filtering is required. To complicate things further a dual frequency transducer is far less sensitive then two single frequency transducers and this is simply due to the fact of the element being less efficient since the element has been charged with two frequencies. To finally answer your question. Dual frequency when producing two cones from a single ceramic element is less efficient, while Dual beams producing separate cones from two separate elements and is more efficient. Best thing to do is ask your manufacturer the configuration of each element to meet your boating requirements.

Current coated cable peels and this new one won't peel.

We make wire in the US

Would you pay $50 for a coated cable that doesn't have peeling issues?

The 2lb Torpedo is not available yet as we are still in test mode, charts are also not available as of yet. We are testing other weights also.

Tank these were test models not available to the public yet. In Michigan fishing depths of 150 to 250 down for kings is now common. I am trying to get an understanding of whether lake O fisherman are fishing these depths. As far as setup is concerned you simply clip them onto your fishing line and lower them down according to a chart.

The weight of that particular Torpedo Diver was 2lbs.

We recently tested a new Torpedo Diver that reached depths of 250'. Would reaching this depth be of interest to members of this board?
