11justin22 Posted October 8, 2012 Posted October 8, 2012 I have a 12 foot v bottom boat that I use on two lakes that are five minutes from me. I load this boat in the back of my pickup and haul it to the lake. I need a graph that I can take on and off while moving the boat around. How would I go about mounting the transducer...I can build something as I'm pretty handy if there are some suggestions. Not looking at spending a ton so a lower end unit is what I want but it needs to be usable. Quote
Super User Wayne P. Posted October 9, 2012 Super User Posted October 9, 2012 If you use an electric trolling motor, put the transducer on the bottom of it. Mount the display to a piece of wood to keep it upright and use the trolling motor battery for power. Quote

I do not want put it on the bottom of the trolling motor as parts of the lake are shallow and I hit the motor ALOT. Quote
gramps50 Posted October 9, 2012 Posted October 9, 2012 They make units that are portable and have suction cups to how the transducer to the boat. I would think that almost any unit could be made to be portable by using a small gel cell battery or run it off the TM battery. There are several possibilities for mounting the transducer, a bracket with a couple of big suction cups, or a c-clamp with a piece on it for the transducer, maybe a spring clamp. Like someone else said mount the head unit on a board to hold it upright, I did this while I was trying to decide where I wanted to mount my front unit. For the graph itself I would get the best one my budget could afford. Look around and mayebe pick up a used one from someone upgranding. Quote

You are correct--I have a portable setup for a Humminbird 1198c SI so I can use it for demos and SAR. Quote

If you hit the bottom a lot with the trolling motor, don't have the motor so far below the hull bottom. You can use a transducer protector that will withstand bottom contact. Transducer Shield and Saver has a model for most brands and types of transducers. Quote
Jim_M Posted October 9, 2012 Posted October 9, 2012 The Humminbird Fishin Buddy 120 does the job for me. Self-contained... http://store.humminbird.com/products/271365/120_Fishin%27_Buddy Quote
moguy1973 Posted October 9, 2012 Posted October 9, 2012 I'd just get some c-channel or a piece of 1/4" stock and mount the transducer to it and then c-clamp or vice grip it to the transom. Lots of temporary mounting solutions really. Quote
Super User scaleface Posted October 9, 2012 Super User Posted October 9, 2012 I fish from a jon boat a lot and was in the same situation. I had an old bow mount trolling motor that no longer worked. I gutted it , shortened the shaft , ran the cables up the inside, mounted the unit on top. .It works great. Quote
Super User J Francho Posted October 9, 2012 Super User Posted October 9, 2012 Mount the TD to piece of wood, and c-clamp it to the transom. Put the graph and the 12v house alarm battery in a small "six pack" cooler from wally world. If you get the one with the plastic insert, you can even screw the base into it. I never bothered, worked perfect just sitting there. Quote
AndyTN Posted October 9, 2012 Posted October 9, 2012 The hole for the oar lock make a great quick release mounting point for a home made rig. Just find the right sized bolt. Negates the need for the C-clamp. Quote
Team_Dougherty Posted October 11, 2012 Posted October 11, 2012 I do not want put it on the bottom of the trolling motor as parts of the lake are shallow and I hit the motor ALOT. If the lake is that shallow I am not sure is a depth finder will work all that well for you. if you have a 20° cone angle you are only going to see a 1/3 of your depth in a diameter on the bottom. example: in 5' of water you will only see 1.5' diameter circle on the bottom. After saying that I have a bottom line 4200 that works great. Quote

Rest is fairly deep 20-30' maybe deeper by the dam? That 4200 unit is exactly what I need. To bad they don't make them anymore..... Quote

This shows 100' of bottom in less than 2' depth. Quote
