This will be my 4th year with the FS10 and I love it!!! I fish big lakes,small ponds and rivers and hav had no issues.My fish finder isn't attached right now because I have it rigged for ice fishing but when I set it up again I'll take pics,for a transducer mount I cut a 1 inch wide 12 inch long arm from a milkcrate attached it with a wing nut and bolt on side of kayak,works great I can easily turn it in out of the water,its a very simple cheap money fish finder Hummingbird 160. Last spring I was overweight I was up to 224 lbs and the FS10 handled me no problem,I dunno about 260 you may want to go with the 12 footer.
