I've used a Fishin Buddy for seven years on my toon. It's an older model. Very durable, marks structure and fish, however it is a 9 degree transducer so the cone is very small in shallow depths. It will mark your jig; but as with all transducers, you must be within that cone.
My buddy used his buddy on the ice this past Saturday at Antero. He uses his through the ice all the time. Worked fine, marked fish and his jig. Great for checking the depth through the ice and looking for weeds. Just a little water on the ice and shoot right through while standing up. Really quick for scouting out your area before drilling.
For what you're looking for...Ease of operation, easy to read...no real learning curve at all. I'm sure he'd love it.
On the ice...discard the mount. Just bring along a five gallon bucket with a hole cut in the bottom. Drill a hole in the ice for the Buddy....flip the bucket over and place it over the hole and put the buddy through the hole in the bottom of the bucket. Sets it up at eye level as you fish.
