Transducer Installation Some of the models covered by this manual have a transom-mount transducer included. There two different transducers that could be packed with your unit. One is a 20° cone angle "Skimmer" transducer that can be mounted on the transom or epoxied inside certain boats to "shoot-thru" the hull. The other tran[...]

Shoot-thru-hull v.s. Transom Mounting (20° Transducer Only) Typically, shoot-thru-hull installations give excellent high speed opera- tion and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer. However, the shoot-thru-hull installation do[...]

2. Slide the tr ansducer between the two ratchets . T emporally slide the bolt though the transducer assemb ly and hold it against the transom. Looking at the transducer from the side , check to see if it will adjust so that its f ace is parallel to the ground. If it does , then the “A” position is correct f or your hull. If the transducer’ s[...]

SHOOT-THRU-HULL (20° Transducer Only) The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A success- ful transducer installation can be made on hulls with flotation materials (such as plywood, balsa w[...]

TRANSDUCER LOCATION (HIGH SPEED) TRANSDUCER LOCATION (TROLLING SPEED) 2. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, as it will cause bubbles to form in the epoxy. Apply a small amount on the face of the transducer as shown above, then spread a small amount onto the sanded area on the hull. Place the [...]

TRANSDUCER INSTALLATION - 8° Transducer Only The 8° transducer is designed for transom mount only. It can be installed on any outboard or stern-drive powered boat. Do not use this transduc- ers on an inboard powered boat. Please read these instructions carefully before installing your trans- ducer. The transducer mounting location is the most cri[...]

RATCHET TRANSDUCER BRACKET - o + o ANGLE OF ATTACK 14 DEGREES This is the way the transducer should look when it's mounted on the transom. TRANSDUCER RATCHET See the chart at the top of the next page for example transducer angles for letter "A" at 12, 14, and 16 degree transom angles.[...]

12 DEGREE TRANSOM ANGLE INDEX MARKS A-A A-B A-C A-D A-E ANGLE OF ATTACK PER RATCHET CLICK For example, with a 14 degree transom, placing the ratchet on the transducer bracket on "A" and the ratchet on the transducer on "C" will result in a +42.0 to -3.0 degree coarse angle adjustment range. +42.0 o -3.0 o +37.0 +31.0 +40.0 +35.0[...]

2. Once you've determined the proper ratchet placement, assemble the transducer and bracket as shown above. Don't tighten the nut at this time. INSTALLATION - Location 1. The transducer must be placed in a location that has a smooth flow of water at all times. Air bubbles created by the movement of the boat hull against the water interfer[...]

3. Don’t mount the transducer directly behind strakes or ribs on the bottom of the hull. Typically, a good location on aluminum boats is between the ribs closest to the engine. 4. Once you determine the best location for the transducer, hold the bracket against the transom. The transducer should be roughly paral- lel to the ground. The bottom of [...]

FLAT-BOTTOM HULL DEEP-"VEE" HULL 6. Route the transducer cable to the sonar unit. Keep the transducer cable away from other wiring on the boat, if possible. Electrical noise from engine wiring or bilge pumps can be picked up on the trans- ducer cable. This can show up as unwanted interference on the sonar display. NOTE: Some aluminum boat[...]

It may save you the trouble of returning your unit. Unit won’t turn on: 1. Check the power cable’s connection at the unit. Also check the wiring. 2. Make certain [...]

3. The water may be deeper than the sonar’s ability to find the bottom. If the sonar can’t find the bottom signal while it’s in the automatic mode, the digital will flash continuously. It may change the range to limits far greater than the water you are in. If this happens, place the unit in the manual mode, then change the range to a realist[...]

NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonar’s display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause the unit operate erratically, or not at all. To eliminate or minimize the effects of electrical noise, first try to determine the [...]
