ok, ive been bass fishing for a while, but new to the whole boating scene.  I have a 14ft jon boat and im about to get a fish finder.  

here are the two im looking at.

Garmin Fishfinder 160C

and the

Humminbird 130 Fishin' Buddy Clamp Mount Fishfinder

heres my problem.  I dunno which one to get.   I like the color display of the garmin, but i like the mounting convince of the fishin buddy.  Any body got any advice one which one i should go with.  

Also if I get the garmin, should I mount it close to the stern where I will be steering my gas motor or close to the bow where my trolling motor is?  Where would it be the most useful? If i get the fishin buddy I can move it back and forth with no problem. any advice would be welcomed.  

On my Jon boats I would mount the finder in the bow & then kick the font size up so it could be easily read from the rear while running.

Just noticed post and Catt's response and I agree with the bow arrangement.

You want to see where you are going and what is under the boat.

Are the models removable?  I would think you would like to remove them and bring them inside so they will not get stolen or damaged when not in use.  

Have you looked at the Eagle Cuda series, they are made for what you are looking for, now they are black and white, at least mine was.  But, they detach easily swivel, and Eagle is made by Lowrance.  

Just something to stir the pot a little as far as options are concerned.

Assuming you have not already looked at them, the Eagle Cuda series is really reasonably priced and I have seen some good reviews on them. I plan on getting one for my jon.

As to how and where to mount it, I had a thread on mounting my tranducer, Team_Dougerty provided this link: http://www.cabelas.com/cabelas/en/templates/links/link.jsp?type=pod&id=0000844 which would help you in temporarily mounting it just about anywhere on your jon. Then you could try different spots until you got one that worked without drilling holes all over your boat.
