Mag for sale.

Charles,


They must all be wired "in phase" so that the transducers all operate or push at the same time.


You begin by cutting the plug off the transducer leaving approximately 7" of cable coming off the end of the transducer. Once cut, you will notice a center wire, which is covered by insulation and an outer stranded wire covered with the outer insulation ... it looks like cable tv wire (only much thinner in diameter). Basically, you connect two of the transducers together ... having two pairs. You then connect the two pair of tranducers together making it into the final array. All connections are soldered, coated with liquid electrical tape, and finished off with shrink tubing.


You then have to test it to ensure that all of the transucers are in sync. Dan has a procedure for perfroming this test. A friend of mine, Garrett Reeve, took the transucers to work and was able to test them dry (Dan's test requires you to perform it in the water) using an o-scope. If you do not have access to an o-scope (most don't, and if I did I would not know how to use it) Dan's procedure would work (and has) fine. We are under a time crunch with such a short boating season that we had to come up with a testing procedure that was quicker. We are two hours away from the boat. The boating season is short here due to the cold weather. Quite often boats are sunk here due to ice build-up on the top of the boat ... not to stable ... new wreck dives.


At some point, Garrett will post his testing procdure as he promied. In the meantime, Dan put together a manual that on putting his fish together. You might want to send him a private e-mail on this subject. It has much more information in it than you will get from my posts. But I have nicer pictures. :)


Hope that helps.


Can you send me the names (and e-mails) of your friends that have Dan's clones? Maybe you could e-mail them, copying me, and introduce us.


Thanks,


Patrick
