I'm sorry, we will not be answering any messages asking "Will this work with..." If you need to ask this question, this probably isn't for you.

We have recently acquired a limited supply of New-Old-Stock P79 transducers. These were originally intended to be used on Cobra depth sounders, but with the correct plug, this can be used on many of the major manufacturer's machines and sounder modules that use a 50/200 kHz transducer with an output power of 600 watts. Please read below for more information. Please note: this will not "Plug and Play" with anything but the Cobra units.

All P79 transducers are essentially the same, whether they're for Garmin, Furuno, Simrad, etc., however, the difference between, say, a P79 for a Furuno and one for a Garmin is the plug at the end.

In order to use this with any other manufacturer's product, you will need to splice an Airmar transducer pigtail (a word that describes a plug with loose wire ends) for the manufacturer you will be using this on. Some of these pigtails are available on ebay and online, some are not. Any pigtail we have will be listed on eBay, we don't have anything in stock that is not listed. Basically, before buying this, make sure you have an Airmar transducer plug for your sounder/module. If it does not say Airmar on the pigtail wire, it will have different colored wires and without knowledge of reading schematics and testing continuity, you will be lost.

Once you have the pigtail and this transducer, we recommend cutting about 3" of insulation back on each, and connecting color for color either by using waterproof/heat shrink butt connectors (red ones, available at any Auto Parts store), soldering and heat shrinking, or a terminal block. Please note: the orange wire in this transducer is the XID wire, this is not required to be connected to anything if your pigtail does not have an orange wire.

Some notes: Raymarine units have some quirks and we advise you to be cautious if connecting to a Raymarine unit. If you have a Raymarine plug pigtail from a 1000 watt transducer, you cannot use this as all 1000 watt Raymarine transducers have a resistor built into the plug that tell the sounder or sounder module that the transducer is 1000 watts. If you ignore this advice splice this into a Raymarine pigtail that was previously used on a 1000 watt transducer, this transducer won't last very long!

The P79 is what is known as a "in-hull" transducer. This is only for solid fiberglass boats, and will not work on metal or wooden boats, nor will it work on boats with any sort of core in the installation area. The flange is attached to an area on the inside of the hull out of they way of any pickups or protrusions that may cause interference. You can use epoxy (my favorite), Marine-Tex (a close second) or 5200 to bond the flange to a roughed up area of the hull. Then fluid (usually non-toxic pink antifreeze) is added to the flange to create a medium for the transducer to fire through and lastly, the transducer is added and adjusted to match the deadrise of the hull.
