I recently purchased a 1993 Hunter 23.5. It has no depth sounder. I would like to install one, but since there are numerous choices out there, I was hoping someone could help me decide which is best. I know there are "through hull" and "transom" mount types, just not sure which is best. Thank you for your input. Bob

transome mount
I've used transom mount transducers, "gluing" them to the hull with silicone type sealant, with good results. Reduces the greatest depth reading a bit, but usually we are interested in the lower depths more.

Bad choice !!!!!!!!!!!
Use the money to buy more "Beer" !!! Who cares how deep the water is?????????????

it helps when...
...picking an anchorage site. Aside from the depth you get a good idea whether or not the bottom is sandy or rocky.

Already on board
You may already have one on board, assuming your keel swings up and down. When you run aground, simply crank up. Otherwise, get a good chart and trim it down to size for where you usually go. As you learn your water, you'll be able to "see" the shoals by virtue of learning the charts and occasionally grounding.

I installed a Horizon depth sounded this winter on my H260. It was easy to install and it works great. So nice to know how much room is under us. I got the transmiter that shoots a beam though the bottom of the boat, so no holes! and there's nothing to fowl the transmitter. The gage is a little black circle about the size of a silver dollar, but the display number's are 3/4" - the same size as the larger gages. Yes, you can buy bigger gages, but the display numbers are the same size. It was easy to drill a hole for installing. And it's fairly cheap. So, I'm happy to recommend it. Good Luck!

I just installed an Eagle Fish Finder on my
1993 Hunter23.5. My wife bought it for me years ago when I had a ppontoon boat. It was a transom mounted transducer. On the 23.5 I used epoxy to glue the transducer ( some of the newer units have a puck to shoot through the hull) to the inside of the hull (inside the starboard quarter locker under the birth, next to the water ballast tank). I first hooked up the unit. I used a zip lock baggie full of water. I placed it against the hull and put the transducer inside to be sure I could get a reading through the hull. Once I found the best spot I placed a piece (3" diameter) PCV pipe about 4" high on the bottom of the insdie of the hull. I put about 1 to 2 inches of clear marine epoxy into it and worked out all the bubbles. I then set the transducer into the epoxy, double checked to be sure I could get a reading, and then proped it up and let it to dry, glued to the hull. In about 90 minutes, it was ready. I then ran all the electric lines underneath to the battery. From the battery I ran the cable up through the locker cover under the starboard inside seat, behind the back of the seat and then used suction cups with small hooks on the indside of the hull to lead the wires out to the dispaly terminal. I mounted the disply on a piece of teak and sit it on the hatch cover glass when sailing. I can see it from anywhere in the cockpit, and didn't have to drill a hole in the decking or hull. I also get to lock it up when I leave the boat. There is an article on shooting through the hull in the April or May Sail Magazine. There have been a bunch of articles on this in the HOW forum. You'll feel better about drinking a beer when you have a depth finder to avoid going aground. Good luck. Hayden @ hayden_jones@renolan.com

Installing a Standard Horizon Depth Sounder
Afternoon Also have a 1993 23.5 and agree with Frank Sears regarding the Standard Horizon depth sounder. Have gotten as far as installing the display on the exterior cabin wall and wiring into the battery. They make a puck type transducer that requries no holes in the hull. The transducer snaps into a clylinder that is epoxied to your hull. The cylinder is calibrated for various hull angles so that the transducer when installed will shoot straight down. The cylinder is filled with mineral oil prior to inserting the transducer so you have a bubble free layer between the transducer and the hull. Have not finished the installation (still trying to see if I can mount forward of the centerboard vice aft of the rear berth (behind ballast tank.) Ron

Humminbird
I used the cheapest fishfinder Humminbird makes, about $100. Glued a shoot thru transducer to the hull under the aft berth behind the ballast tank. The readout is mounted on a stalk on the head bulkhead, so that it's visible from all points in the cockpit when tilted out, but enclosed in the cabin when the companionway is closed. Works great. My boat is a 26, but most of this would apply to the 23.5.

uno problema
unless you buy an expensive one they are not much good.By the time the depth is shown on the meter you are aground. The cheap ones don t read forward,just under the boat.

ST40 Bidata System
This spring I installed a Raymarine ST40 Bidata System which has depth, speed and temp all thru the hull. The installation took me about 2 hours. We love the system and we would not be comfortable sailing in unfamiliar waters without it. If you are interested in more info, e-mail me at r.bridge@att.net.
