Scores are our editorial opinion of these models, based on features, suitability and ownership trade-offs—not hands-on test results. How we chose →
We’d pick the OSTC+.
We’d start with Heinrichs Weikamp OSTC+. We would shortlist OSTC+ for its 2.4-inch screen, recessed controls and choice of sport or technical firmware. Choose Sherwood Scuba Wisdom 5 instead if its strengths are a better match: our console-format choice when you want a hose-connected computer and compass together instead of another device on your wrist.

What the differences mean when you buy
Display and control format
Heinrichs Weikamp OSTC+
- Display
- 2.4-inch LCD-TFT
Sherwood Scuba Wisdom 5
- Format
- Hose-connected console with compass
Look at the main information at normal wrist or console distance, with your usual vision correction. Display technology and diagonal size are useful facts, but they do not predict your ability to read smaller secondary information. Try menu navigation and controls with gloves. A feature upgrade within one family may retain exactly the same screen size.
Pressure monitoring and compatible accessories
Heinrichs Weikamp OSTC+
Ask the brand about this detail before ordering.
Sherwood Scuba Wisdom 5
Ask the brand about this detail before ordering.
Identify whether pressure comes from a compatible wireless transmitter, a direct hose connection or a separate instrument. Optional support does not mean the accessory is included. Confirm the exact transmitter generation, number supported and installation requirements. A shared radio concept or brand family is not enough to assume cross-model compatibility.
Battery, modes and ownership
Heinrichs Weikamp OSTC+
Ask the brand about this detail before ordering.
Sherwood Scuba Wisdom 5
- Battery
- User replaceable
- Modes
- Air, nitrox and gauge
Check the current manual for supported modes and settings rather than relying on the computer’s price tier. Rechargeable and replaceable batteries create different travel routines. Confirm approved battery types, charging hardware and the supported logging workflow. An algorithm name is not a promise of identical behaviour across computers or firmware versions.
A closer look at both
OSTC+
The current OSTC+ pairs a 2.4-inch LCD-TFT display with two recessed sensor buttons. Heinrichs Weikamp offers hwOS sport and TECH firmware, wireless charging and Bluetooth connectivity. An optional Fischer or S8 socket is a separate configuration for compatible oxygen-monitoring applications.
What we like
We would shortlist OSTC+ for its 2.4-inch screen, recessed controls and choice of sport or technical firmware.
What would make us think twice
Check the firmware included in the price; an optional sensor socket is a separate configuration.
More about the OSTC+ →Wisdom 5
The Wisdom 5 is a hose-connected dive computer console with a liquid-filled compass and high-pressure quick-disconnect hose. It provides air, nitrox and gauge modes, two-button navigation, audible and visual alarms, and Bluetooth integration with DiveSync. Sherwood specifies storage for 60 dives and a user-replaceable battery.

Our console-format choice when you want a hose-connected computer and compass together instead of another device on your wrist.
What would make us think twice
A console changes how you route and read the equipment; Bluetooth here is for logs, not wireless tank pressure.
More about the Wisdom 5 →Four checks before you place an order
- Try the display and secondary information at the distance you will actually read it.
- Confirm required diving modes and the exact model or wired-system variant against the current manual.
- Identify compatible transmitters, chargers and any separately purchased installation parts.
- Review battery procedures, firmware support, logging compatibility and local servicing before paying.
Ask for a quote for the complete kit, including the accessories you need. That makes the price comparison much more useful.
Price, accessories and owning the equipment
Request a computer-only and complete-system price if pressure integration is part of the decision. Transmitters, charging accessories and installation can change the apparent upgrade cost substantially. The price of replacing accessories you already own belongs in the comparison as well; do not assume cross-brand or cross-generation compatibility.
Upgrade for a feature you will actually use: a clearer display, tank pressure on the wrist or a mode your diving calls for. We would rather have a readable everyday screen than a long menu of functions we never open.
How we scored these models & further reading
These are our subjective buying scores out of 100. We weigh the usefulness of the features, the intended diving or carrying job, and the compromises involved in owning the gear. They are not laboratory measurements, safety grades or customer averages. The verdict applies to the two named models, not everything either brand makes.
90–100: one of our first choices for the stated job. 80–89: a strong option with trade-offs. 70–79: a more specific fit. A different fit, camera, valve or dive plan can change which one you should buy.

Product details and further reading →Questions worth settling
Can I make the simpler model equivalent by adding a transmitter?
Only if that exact computer supports the compatible transmitter. Optional accessories cannot supply a capability the base computer does not have. Check the model-specific manual and the full compatible package before buying either component.
Which is the better buy for this particular comparison?
Heinrichs Weikamp OSTC+: Check the firmware included in the price; an optional sensor socket is a separate configuration. Sherwood Scuba Wisdom 5: A console changes how you route and read the equipment; Bluetooth here is for logs, not wireless tank pressure.
Our pick is where we would start. Choose the other model if its fit or features better match your setup—especially where a camera, valve, boot or exposure suit needs an exact match.
