“Now we have a mobile unit to find structure and fish”
Dave Kyle
Situation: Uses rented boats for bass fishing and needs a versatile, mobile depth finder
“On the rented boats you just couldn’t take a depth finder, you couldn’t see the structure you were floating over. Now we have a mobile unit to use and find that structure, target the fish we’re after and have a successful day out on the water. The mapping helps a lot. Maybe you might have missed something while you’re fishing, but you can study that later and be quicker to the structure.”
More ReviewsThe power to match traditional boat sonars, with added versatility
We asked Josh and George from Pocono Outdoors Guy to put the Deeper Smart Sonar PRO+ head to head with a Humminbird Helix 10 – a unit that costs over $1,000. George’s verdict? “We’ve seen the same things – bait balls, fish, weeds, they all show up perfectly on the Deeper, just as they did on the Humminbird.”
And compared to traditional boat sonars, Deeper units offer incredible mapping features free of charge, plus unmatched versatility.
