Product Description

Fishfinder, RF15, Smartcast Series


The Humminbird Smartcast RF15 is a fishfinder designed for the recreational angler ready for a step up from traditional fishing and offers an unmatched level of convenience. This fishfinder may be small, but it has plenty of built-in capabilities, and can provide you with the ultimate in portable sonar in a simple, rugged package.

The Smartcast RF15 utilizes a traditional, single-beam 90-degree sonar to deliver ultra-wide coverage equal to twice the water depth up to 100 feet deep. Vital information is displayed on a big, 3.875-inch display with 160x132 lines of resolution, in a true four-level grayscale that delivers clearly better images of the bottom, fish and structure. The large, easy-to-see digital readout includes a backlight for night fishing, and is powered by eight AA (not included) batteries. This system is designed to be waterproof, and has a 100-foot operating range allowing you to easily travel around without losing your signal.

The Smartcast RF15 comes with a waterproof, programmable Advanced RSS (remote sonar system) for either Channel A or B operation mode, as well as a rugged carrying case with a non-skid bottom and RSS storage. The new illuminated, advanced RSS includes water surface temperature, typically lasts for 500 hours of in-the-water usage, and allows you to purchase replacements that are available on the manufacturer's web site, as well as at your local tackle dealer and major outdoor retailers. The Smartcast RF15 features one-touch menu navigation that allows you to easily control FishID+, depth range, fish alarm, and sensitivity, as well as Wet Switch technology that maximizes battery life by automatically shutting down when the Advanced RSS is out of the water. For those who like to travel light and go fishing anywhere and everywhere, this system is the perfect companion.

What's in the Box
RF15 control head, advanced remote sonar sensor, portable carry case, and operation manual.

Got this as a gift for Christmas when I was shopping with the wife at BassPro here in Orlando. I had been researching these units for a few days after reading about one online. The fact that I could cast out from the shore appealed to me so I chose one of the smartcast models. BassPro had the RF10 on sale and the R15 was the price I had expected the R10 to be so I went with the R15. It includes grey scale and water temp as part of the upgrades from the R10 series.

Over the past two weeks I've taken the R15 out to 4-5 lakes around my area to test it out. Provided I do a nice steady retrive a smooth display of the bottom is presented. I have also seen a fair amount of fish on the display using the Fish ID function. From what I have read on various newgroup posts this feature should generaly be turned OFF. Instead one is supposed to learn how to identify fish using "raw" sonar returns. So far I have not seen any "fish arches". I have a feeling I might need to be in deeper water for this to occur.

Overall the detail is nice and there are four options for displaying the 4 gradations of grey in ordet to highlight either weak or strong returns. One of the limilations of using this near the shore is that is does not do well with shallow depths. It lists 2 feet as the minumum but even depths of 3 feet and a bit more seem to confuse it, giving false returns. I have not tested its actual ability to recognize a return as a fish yet. I say this becuase so far I have not taken my tackle out, just the fishfinder in order to concentrate on learning it. I think I will try adding some bait to a line and attaching this to the small hole provided on the bottom of the RSS to see if it will show any fishing coming up to check it out.

I'll tell you i did alot of research on this product before i finally decided to buy it, You know how you can always get caught up in the hype of good reviews and bad reviews. which in a lot of cases can sway your decision on buying a certain product. Well I bought it, ive taken it out on 3 fishing trips so far. all freshwater lakes. i dont have a boat so im always hoofing it along the shoreline carrying my 3 poles and backpack full of tackle. if this sounds like you, then i highly recommend you get yourself one of these. We all know when your at a lake and you cant just cruise around in the middle it can be hard to find that perfect spot where the fish are. this thing has helped me in that. no longer do i have to move around all over and still have nothin to show for it. this allows you to at least find those underwater ditches or deep cover that you can never normally see. you can fish everywhere on a lake all day and by the time you get to your new spot the fish have already moved.I got my package and there was nothing wrong with the RSS or the fishfinder unit. it mounts great to the fishing rod and ive had no problems with the unit dieng or rusting or screen cracks. nothing. i wanted to submit this review because i know what a negative affect negative reviews can cause. so please. if your interested in buying this. i suggest you do so. a must for the shore tracker. good fishing!

Have had this for about a week and took it out a couple of times.
As other reviewers have commented, it works quite well. After messing with it, I can't imagine fishing without one. Knowing where the fish are and are not is invaluable. Of course it can't tell if they're biting !

A few observations to add to the already good reviews of this product:

1) The RF45 "rubber ducky" unit that you cast into the water is smaller than I expected, but that's good. It is light and casts well.
2) The display you wear on your wrist is a somewhat large, and thick, watch. This is fine. The resolution was good enough to see what needs to be seen, and lack of greyscale does not seem to compromise the utility.
3) The user manual is very well written, but as you might expect for something with few buttons, it takes some study to understand what you've bought. The operation of the watch-unit took a while to learn initially, but is straighforward after you use it a couple times. (It has defaults, so you can probably just use it if you don't want to study the manual...)
4) The RF45 rubber-ducky seems faily durable. I actually dropped mine on the concrete and it bounced and survived. But I don't recommend repeating this experiment.
5) The display unit I got had a bit of a manufacturing quality-control issue. All the pixels were quite dark, requiring me to find the part of the manual that explains how to adjust the LCD contrast. After setting it on the lowest setting (1, rather than the default of 5) it seems to work fine - but I wish I could adjust it even lower.
6) While not needed, "programming" the RF45 rubber-ducky (if you want to switch channels, turn on the light, etc) is a bit cumbersome, and can't be done without the manual.

I've now had this little guy for a year and with the exception of the green transducer dying in the first week (replaced immediately by Humminbird), it works like a charm. It's been in both frest and salt water repeatedly without a hiccup. I've had it in as much as 60 feet with fairly good resolution, discerning between weeds, rocks and fish
well for the price. Great little unit for the money, for sure-especially if you have a kayak like me. You won't be disappointed.
