Mojo said it better and with fewer words than I can and I really don't mean to pile on. But, for what it's worth.
The term “ Most “ anything always bothers me.
So when someone say's that most float tubing takes place in shallow water? Maybe where you’re at, but that is certainly not the case here, never has been.
The assumption that sonar isn’t effective in shallow water? I think we need to define the words shallow and ineffective.
Think of all the money that could be saved by glitter boat jockey’s if they knew going in, that those side finders and wide beam transducers weren’t effective. Seems there’s an entire industry built up around the use of sonar in shallow waters.
No one will ever convince me that moving a sonar beam slower, will somehow provide a less accurate portrait of objects, than it would be if that the transducer was moving at forty miles per hours.
There are countless western anglers who safely fish enormous lakes and reservoirs that would take issue with these statements along with some well known anglers who made their mark and their living doing both.
As for the use of sonar, ask a guy like Dan Blanton if he’s ever called his shots ( casting to and hooking a specific target ) with a side finder, even one as simple as a fishin’ buddy.
I’ve done it and demonstrated it numerous times in land-locked striper and black bass clinics, from float tubes, pontoon boats, prams and skiffs. Not drawing a strike doesn’t mean the sonar’s not working, it means your presentation isn’t working. I’ll put my money on the sonar’s ability to locate large gamefish
over some anglers
ability to catch fish, almost every time.
Look around this site, you’ll find old photo’s of Del Canty a pioneer in float tubing on large deep western reserviors with fish that’ll simply blow your mind. Run a search on-line for the float tubing practices and successes of Lee Haskins on large and deep, San Luis reservoir.
The usefulness of sonar as an adjunct to a fly fishers arsenal is well documented.
Those two black objects leaning on the float tubes are fishin' buddies. While they're very good at locating structure, they're also very good at finding schools of baitfish. They've accounted for thousands of Stripers and other gamefish and many of those were from calling my shot, with a single large target on my side finder in waters from 8 to well over 100 feet deep.
All the best, TT
