## Questions & Answers

**Q: Can you see a small jig / lure when ice fishing for perch and walleye?**
A: I fish in the spring thru fall seasons and I can see a large crank bait.  I would doubt you can see small ice fishing lure.

**Q: How do you mount the110 on a kayak?**
A: I checked their site, Humminbird makes a mounting bracket - (from their website) 740095-1 Fishin' Buddy Mounting Bracket Fishin' Buddy 110, 120, 130, 140c    I found it in Amazon: B0012ITC6C

**Q: I want to make sure before I buy this, Does this unit have the side finder??**
A: Yes it does have the side finder option along with regular verticle viewing, for a small unit works real well.

**Q: Anyone use this with a molded Kayak?  I have a Native Watercraft 12ft yak and I'd like to try this fishfinder but I don't see how you'd mount it.**
A: I have a a couple of Kayaks also but I didn't buy it for them. I don't know how you could make it work on one. The mount is adjustable but you don't have anything to clamp it to. Short of bolting a short piece of angled metal to the hull so would have  something to clamp it to. Probably don't want to do that! Take care! -Jim

    It was great. The reservoir I fished ran deep (180 max) ...
  

*by S***Z on Reviewed in the United States on July 20, 2014*

I took the Humminbird Fishing Buddy to a NYC watershed this past week and used to for the first time.  It was great.  The reservoir I fished ran deep (180 max) with several sharp drop-offs, so I figured it would be a good test of the fish finder's ability.  Clamping it on to the canoe took 3/4 minutes and was simple.  The transducer and screen module slip right in and out of the clamp which was great for approaching shallow water (popped it out and tossed it in the canoe).  It took me an hour to learn how to use it correctly.  We were drift fishing and at first I tried to catch fish directly under the canoe, which didn't work because of the drift.  I then realized that I should have my bait drift trolling 30 feet behind the boat so I could adjust the depth of the line/bait to match the depth of the  fish as I saw them.  I used depth hunter color coded line (different color every 25 feet) tied onto a good leader so I knew exactly how deep my bait was.  It worked beautifully.  My buddy hauled in 2 gorgeous 20 and 22 inch brown trout and I got a 16 and 18 inch brown trout and a 18 inch smallmouth using this technique.  I just bought a drift anchor so I can drastically slow down the canoe in current/wind and fish directly beneath the boat using the fish finder (jigging for summer lake trout in the Adirondacks next week).  The readouts on the screen were crystal clear and marked small, medium and large fish at their exact depth.  Most importantly, I was able to see where in the water column the fish were holding, which is important as their depth changes day to day with the weather, barometric pressure and temperature.The only drawback was that when paddling at a moderate rate the fish finder (with the transduce rod in the water about a foot and 1/2) began shaking like crazy, so, any time the boat picked up speed I had no pop the transducer out and put it in the canoe.Suggestions:1. Use color coded depth line.  Without it, even though you know where the fish are, the depth your lure/bait is at might not be near the fish.  2. I bought a 25 dollar c-clamp Eagle Claw rod holder on amazon.  It's awesome to use with the fish finder for drifting/trolling.Overall, this thing is great.  Buy it!  For the price, it drastically enhances your fishing and is easy to use.

    Great Portable Fishfinder.
  

*by C***T on Reviewed in the United States on September 4, 2012*

This is a great, truly portable fishfinder.  It performs very well, the side-scanning feature works well and something typically found only in much more expensive fishfinders, and rarely in something portable.  The temperature reading is quick and seems to be accurate.  I like that it has its own power source (AA batteries -- just buy some rechargeables) rather than requiring a 12v source, the screen is decent resolution, the functions are fairly easy to figure out without consulting the manual all the time (you may need to glance through it the first time, especially if this is your first fishfinder), and the craftsmanship is excellent.All that being said, I purchased this fishfinder for my fishing canoe, and it doesn't work very well for that.  The canoe is just too shallow of a hull, so when you clip the fishfinder to the gunwale, the transceiver hangs down pretty far under the surface of the water, making the depth reading a little inaccurate.  I guess it might actually help the sidescanning feature.  I'm probably going to devise a higher mounting point for it (using the thwart on my canoe) so that just the transceiver is in the water.  I think that will also help with the wobbling that occurs in the cup mount when I'm trolling along at higher speeds.  If you're not feeling 100% confident in your mount location or if you encounter a lot of wobbling with your style/speed of boating, you may want to rig a leash on it.  I could easily see losing this to Davy Jones' Locker.I also purchased the carrying case for this.  It was a little on the pricey side, but it works very well to protect this device, and I'm glad I sprung for it.All in all, a very nice fishfinder -- not perfect (hence 4/5 stars), but it's probably the best portable one on the market today.

    Good Fish Finder
  

*by B***. on Reviewed in the United States on July 8, 2010*

I bought this fish finder late last year and put batteries in it when I got it so I can play with it a little.  Started using it this spring with the same batteries and it works great, used the unit about 4 times all day long and still did not change the batteries yet. This fish finder is great for a small boat "I have a 12 footer".  It is very easy to use but you need to take it out of the water when your moving.  The bracket that comes with it makes it easy to do that, you can tilt it out of the water or pull it right off the mount (pops off easily) out of the water to place inside the boat.  You cannot leave it hanging in the water at speed it will pop off the mount. The mount lets you rotate the unit around very easily and the unit itself is pretty rugged as well.  Again for a little boat this is perfect if I had a bigger boat I would opt for a fish finder with a permanent mount.Notes:Very PortableEasy to useRuggedGood battery life
