Great fins. Good propulsion. I do find them a little long for wreck diving when frog kicking. Thinking an additional short fin version for wreck/cave.

I lost one after several years of them being my favorite fins and didn't hesitate to get another pair.

Negatively buoyant which is desirable wearing 7mm suits here in CA... Super strong, and durable... Leading dives you have to be careful you don't wear out your divers...lol

Decent fins for tech diving as they can be used with different style kicks. A bit heavy so don't lose one in the water. Good solid spring straps that will hold a sock, shoe or bootie. May have to size up for a boot as it was a bit tight on mine. The weight and function remind me of the original SP jet fins.

I needed a more negatively buoyant fin for drysuit diving. The Hollis F-1 all but eliminated the floaty feet I was experiencing. The spring strap with the large finger loop makes donning and doffing easy.

EXCELLENT FINS!! QA little on the heavy side but in open water they perform spectacularly. Vey happy with them!

I have the Hollis F1 for my drysuit, they are heavy but that's what I was looking for. Good power and control.

These fins are very comfortable, extremely powerful, and don’t require alot of force to move you around in the water. They are very slightly negatively bouyant, maybe 1lb. Plus the yellow tips have everyone on the beach asking what fins I have

Needed funds that were slightly negative buoyant. These fit the bill and have worked well. The yellow tips have an added benefit when visibility is less than optimal.

Fantastic for tech diving with double tanks, incl. frog kick.

Never had my dive buddies ask me to slow down till I got these! IMO they are the best tech fin made. Good for any kick style and you might even find a new one or two

Awesome fins and are super comfortable. Great power with little effort.

Heavy, BUT I will not go anywhere without them. Saved me numerous times in strong currents.I lowered travel weight on other gear so i can travel with these fins

Best fin you can expect for tech diving. Large pocket for even rock boot or drysuit boots. Good sturdy design and reliable spring straps. Best value from LeisurePro

The F1 is a fin that plays in the same league as the Scubapro Jetfin. I own a pair of each, and I like different aspects of both. Application: Like Jetfins, I find F1s too negative for single-tank wetsuit diving (which is clearly not the intended field of application!), but they trim me out just nicely for anything from double AL80s (3-mm wetsuit +2/5 mm hooded vest, aluminum backplate, no weights) up to heavier loadouts (drysuit, multiple stages, CCR). Comparison with Jetfins: The main differences compared with Jetfins are the foot pocket, length, and weight distribution. I find that the F1 foot pocket is a better ergomomic design that envelops a greater portion of my foot and gives me better leverage than I get with Scubapros. F1s are also longer by several inches – doesn't matter much in open water, but it's a slight disadvantage in confined spaces like wrecks and caves. The fin's weight distribution is heavily biased toward the foot pocket, which makes the F1 unexpectedly agile for its size and weight when it comes to precision finning techniques. Do not buy if: There are much better fins available for tropical wetsuit diving in a single tank (Mares Avanti Quattro, OMS Slipstream, Dive Rites). Also, do not buy this fin if your preferred method of propulsion is flutter kicking, or if you need to kick constantly to make up for deficiencies in your trim or buoyancy control. Or better, do buy these fins and let the leg cramps light your way to proper technique. Summary: The F1 is my favorite fin for OW technical diving and a close contender for wreck and cave. Love the foot pocket, and I only wish the blade was a little shorter and wider.

Wonderful alternative to jet fins, if you want the same power and durability without having to purchase spirit spring straps. Everyone I know uses jet fins but I personally can't because they cause me pain on the upper of the foot box. I really enjoy that these offer a deeper more stable fit in the foot box. Will likely buy again. Another plus is that they are slightly negative so they help for people who suffer from floaty feet!

A great technical fin from Hollis with solid construction, worth the price.

Excellent fins for any type of diving, but defintely my go-to fins particularly with the weight requirements of technical diving. Already had a larger size pair for drysuit diving, and had the Hollis F-2s for wetsuit technical, but the F-2s just didn't provide the required thrust to meet the needs odd a of technical diver bearing a heavy load. Purchased a smaller sized F-1 fin set for wetsuit technical and they did the trick! Love these fins! They are not overly heavy and have great thrust and agility for helicopter turns, etc. Highly recommended!

Starting with their look they are beatifully styled, easily the 'cutest' fin that I have ever seen. But more importantly is their functionality. I bought these a couple months ago, and have about 12 dives in them, boat dives, shore dives and heavy river current dives. I needed a versatile fin for these wide-ranging Ontario dives that I find myself doing. These fins fit the bill perfectly! They are heavy, but not crazy heavy like the jet fins, and I thought my legs might hurt using them, but I haven't gotten fatigued yet, and I have had some lengthy kickouts with them. My other pair of fins that I love are the mares avanti quattro plus in black, but these F1s have quickly replaced those as my fin of choice. Sizing is pretty right on, I would say, but if you are using a drysuit boot, go up a size more than you thought you would need. I bought the XL but still find it getting stuck on my boots, so I appy a little armor-all on the pocket interior before dive weekends to successfully make the boot easier to get out of the pocket.

Though I dive with multiple tanks and in a dry suit in California waters, I have been using Scubapro Twin Jet split fins for years as they are comfortable and gave fine control. But swimming upstream in a current seemed to need more power. I tried recent Atomic fins but found them to be too stiff and the spring strap buckles opened twice in kelp forests when kelp wrapped around the fasteners. This happened on two different pairs. When I saw these F1 bat fins, I tried them as they are more like traditional broader paddle fins. Result: While stiffer, they are easy to get used to and do indeed provide more power and quite good control for finning in reverse or rotating or station keeping or frog kicking. And the spring straps with the large loops as a handle make very easy donning and doffing. These look like excellent heavy duty fins. Yellow fin tips make it easier to be tracked by dive buddies in poor viz.

Unless you do a lot of diving 3 times a week stay away from these fins! I went from OMS to these and it took 15 dives to get use to them, I dive in a very strong current and need to move fast. Can fell the burn on the second dive.

I use the F1s for just about everything. When teaching I like that they are heavy so its easy to demonstrate skills with them without my feet floating. In the ocean I like that they are very powerful and that I can kick through currents when needed where as with other fins I would not be able to. They are very powerful and efficient, you seem to get every ounce of power you put into them back with each fin kick. I will warn that they may be a little too much for new divers. My first pair of fins were the F1s and I too was warned that they are extremely good fins but take a good amount of leg strength. So for about 8 weeks I used them every weekend and would get leg cramps every time I used them. So I bought a different pair of fins that were easy on the legs, which I thought I liked, until I was talked into giving my F1s another try. When I did I was shocked by how powerful they were and with repeated use my legs got strong enough to use them without issues. Not that diving is about going fast and speeding through the ocean, but if diving was a race, these are the fins that would win it. I love them now, and decided to buy a second set for my drysuit. Which I bought from LP a few months ago. Love the spring straps, and everything else about them, they are built like tanks too.

- It is heavy. This is not a bad thing but if you are not confortable with this you will take some time to adapt, after this adaptaion you will see that a good buyoancy ask some additional weight on you foot. - Great rubber quality, great design, great springs

As a divemaster these fins are perfect, the yellow tips can be spotted even in low vis dives.

I bought these fins for my boyfriend. They were the right fins and they were cheaper than I could find them elsewhere on the internet. However, despite being advertised as new, they were used when I received them. Because he was using them on a dive just a few days after I received them, I did not return them. Otherwise, they are good fins and he enjoyed them very much. I was just disappointed that they were used.

The disign looks very nice, but it is way too heavy and stiff, for a medium small person (150/170lbs) Be carefull and make shure you will be cofortable with this fins. I think this fins will fit perfect to a heavy diver with a dry suit or somebody with buoyant legs. I'm size 9 and allmost my entire foot fits in the fin.The space inside the fin is quite generous.

Powerful, fantastically manoeuvrable, beautifully made. These are for the Pros, if you are not used to stiff, powerful fins they may take some getting used to. Personally, I love them. Great for accurate manoeuvring in caves and wrecks; nothing else quite like them on the market. The yellow tips let everybody recognise me underwater. Heavy out of the water, perfectly balanced in the water. Worth every cent x2.

Easy to put on and take off. I only used them on 1 dive but they worked out fine for me. They are heavy but thats exactly what I wanted because they help me trim out better.

I'm a master diver and have been diving for well over 20 years. Been a die-hard fan of my old Dacor Turboflex fins that I've had forever. Recently, I started taking the Dive Master courses, and the skill testing includes timed exercises including diver tow and 800 yard swim. I have been training for a couple of weeks now, swimming the 800 yards daily, and had hit a wall in my time. I changed to these fins today (thanks Leisure Pro), and knocked 25% off my time right out of the gate on the first use of them. Can't say enough! More power… less energy. Got toward the end of the 800 yards (24 laps in my pool) and had enough left in me to sprint the last lap, which has never happened before.
